Raw Blame History

List of significant changes and bug fixes going back to version 1.1.0
2. Changes in version 2.3.3
Improvements
* Equalization effect now split into two effects, Filter Curve and Graphic EQ.
* Presets (using manage button) now active/working.
* Can now have two points at same frequency for steep steps.
* 'What you hear is what you get' for exports. Formerly the solo button
preferences could lead to differences in which tracks were exported.
* Leading silence (blank space) not skipped over in exports.
* Quality setting on AAC/M4A exports.
* Some confusing functionality removed (better achieved in other ways)
* Removed Nyquist Workbench (use built-in nyquist features)

Bug Fixes
Over 90 bugs in 2.2.2 fixed, including:
* Windows: Queen Mary 1.7.1 Vamp plug-ins crash Audacity on opening
Plug-in Manager - bug #1244
* Inconsistent behavior when recording with a selection defined - bug #1839
* Ctrl + M does not open label for editing - bug #1852
* Vertical Zoom in by clicking in the vertical Scale, or context menu, in
waveform views is inconsistent - bug #1810

* Timer Record with a selection present can get a truncated recording with
data loss - bug #1851
* Duplicate shortcuts can be created - bug #1786
* Labels longer than 260 characters are now supported - bug #1905
* Using Spectrogram Settings in TCP or using Preferences causes Audacity
to reset Project Rate to default rate in Quality Preferences - bug #1977
* Cut Preview should play all selected/sync-locked tracks, respecting
Mute/Solo during preview - bug #231
Changes in version 2.2.2:
Improvements
* Dropout detection
Dropout detection is controlled from a setting in Recording Preferences
called "Detect dropouts".
When this setting is "on" (default setting) Audacity will detect dropouts
(brief gaps in the recording) and will insert zeroes into the recording
to keep the other good parts synchronized. These silent spans will make
the dropouts more obvious, but keep the duration of the recording correct.
When recording stops, a Warning message box alerts the user and a label track,
called "Dropouts", is added showing the lost parts, labeled with consecutive numbers.
* Improved horizontal zooming
For this release we have improved the way zooming using your mouse wheel
works and provided a new Zoom Toggle function.
* Improved vertical zooming
We have added a context menu to the vertical scale to control vertical zooming
Previous vertical zooming methods (left-click in the vertical ruler, left-drag
in the vertical ruler) remain available by selecting "Advanced Vertical Zooming"
in Track Behaviors Preferences.
* "Extra" menu
The "Ext-Bar" and "Ext-Command" menus have been consolidated into the "Extra" menu.
* Theme tweaks
The appearance and/or contrast of a few icons has been improved.
* Easier access to changing key bindings for shortcuts
For menu commands that are enabled (not grayed-out) if you hold the Shift key
and click on the sub-menu item, instead of executing the command the Keyboard
Preferences pop open at the chosen command. You can then change that (or any
other) shortcut binding.
* Language selection in Preferences
Interface Preferences has been upgraded so when selecting languages the proper
spelling of these languages is shown with accented and special characters.
Bug Fixes
* Multiple use of "Save As" to the existing open project can result in data
corruption/loss
* Crash undoing during record, using Discard button of History window
* Exporting audio in compressed formats to device with insufficient space produces
inconsistent/truncated results
* In Export Multiple, Cancel does not remove the file that is in progress when
Cancel is chosen
* Unicode page encodings fixed ( ͡° ͜ʖ ͡°)
* Crash using SBSMS pitch change at low sample rate
* (Mac) Equalization: "Telephone" curve displays a flat line, no sound on Preview
* Toolbars: open undocked if previously not shown, unless Reset Toolbars first
* Analysis effects that create labels should give focus to label track
* Control value may be out of range when using FloatingPointValidator
* Analysis effects produce false indication that a label is open for editing
* Import Uncompressed File Dialog Incorrect Reference to Menu Item
* Wave Color not grayed out in TCP dropdown menu when in Spectrogram view
* Hover indication on note track channel toggle appears on all tracks (when
they rerender)
* Installer has old logo for 2.2.1 and 2.2.0
* Un-muting with a single track unnecessarily activates the Solo button
* Applying chain to file should zoom-to-fit
Changes in version 2.2.1:
Improvements
* Waveform colorways
You can optionally change the colorway of the waveforms displayed in your project.
The setting is per track and not per project so you can have multiple colorways
in the same project.
* "Save Other" reverts to "Export" in the File menu
When we made the menu changes for 2.2.0 we introduced an entry into the File menu
called "Save Other" which led to a sub-menu for exporting various audio formats.
Many users were confused by this change and found it hard to find where they could
export audio from. So for 2.2.1 we have changed that menu entry to be File > Export.
Bug Fixes
* Release 2.2.1 was mainly a maintenance release.
Soon after the release of 2.2.0 we discovered some problematical bugs in Audacity:
Bug #1767 - Opening a second project from Mac's Finder produces a second
inaccessible instance of Audacity
Bug #1770 - Crash applying certain chain files
Bug #1783 - Preview fails when selection extends before zero
Bug #1787 - Auto-scroll stopped working in 2.2.0
Bug #1765 - Using File > Open to import audio gives wrong zoom level
and no scroll bar slider
Changes in version 2.2.0:
* Four Selectable themes provided, with new 'Light' theme as default,
plus option to customize
* Many menu changes:
* Menus Reorganized

streamlined text on landing pages for in-program help.
Other Changes
* Append-record is now the default (use Shift + Record for old behavior,
to record on a new track)
* The Esc key now cancels all click-and-drag actions. It also chooses among
overlapping mouse click targets, which is especially useful in the Multi-Tool.
* Sync-Lock button removed (use menu item or keyboard shortcut instead)
* New preferences and preference pages
* Overhaul of much code:
* Overhaul of envelope handling code to deal with some anomalies
* Overhaul of exception handling for greater safety

Bug Fixes
* Major work on bug fixing. 198 bugs that were in 2.1.3 were fixed for 2.2.0.
* The most serious bug fixed this time round was bug 437 which was
about what happens when Audacity is recording and runs out of storage.
* Most of the bugs fixed were more minor, such as bug 463 which was
about a case in which the numbering on the timeline could display
incorrect times.

ended.
* Contrast: "Move forward or backward through active windows" did not
refocus Contrast.
* LADSPA and LV2 generate plug-ins failed when white space selected.
* Mac OS X
* Confusing behaviour importing / exporting AU presets. In particular,
Apple Audio Units silently applied an imported preset.
Changes in version 2.1.0:
* Effects:
* LADSPA, VST and Audio Unit (OS X) effects now support real-time preview,
save/load of user presets and saving effect settings across sessions.
Note: Real-time preview does not yet support latency compensation.
* VST effects now support import/export of FXB preset banks.
* Shell VST effects that host multiple plugins are now supported.
* All Effect Menu items (built-in or plugin) can now be used in a Chain.
* Items in the Effect, Generate or Analyze Menus can be sorted or grouped
by name, publisher or class of effect.
* Noise Removal is improved and renamed to "Noise Reduction".
* Change Speed has new time controls for current and new length. You can
now enter the speed change as a multiplier e.g. "2" is twice as fast.
* New "Crossfade Tracks" effect can be used for crossfading two tracks.
This replaces Cross Fade In and Cross Fade Out.
* Nyquist Prompt and most shipped Nyquist effects now have Preview button.
* Interface:
* Redesigned Meter Toolbars: The default shows separate Record and Playback
Meters, half-height so they can be wider while docked, in gradient style.

to those frequencies) when in a spectrogram view. You can also create
or adjust frequency selections in a new "Spectral Selection Toolbar"
(available at View > Toolbars).
* Transcription Toolbar (Play-at-speed) can now loop play and cut-preview.
* Timer Record now saves recordings automatically into an existing project.
* New Armenian translation.
Bug fixes:
* Interface:
* Typing "j" or "k" in a label track activated the "move cursor" shortcut.
* Spectrogram log (f) view displayed incorrectly until vertically zoomed.
* Fixed crash after zooming out on vertical scale beyond +/-1.0.
* Selections made with Selection Toolbar were not restored after Undo.
* Undo could fail silently if a selection included/touched a clip boundary.
* Imports and Exports
* If there were invalid FFmpeg libs in system PATH this prevented Audacity
recognising the installed FFmpeg or the FFmpeg specified in audacity.cfg.
* Mac OS X:
* Fix uninitialized buffer - this should correct playback buzz or crackle
where the upper of multiple tracks started with or contained white space.
* Device names were corrupted when using system language other than English.
* Fixed crashes using (external program).
* Waves v9 Audio Units should now work correctly.
* GNU/Linux:

* Please report any issues with WASAPI recording/playback or Yosemite
to http://www.audacityteam.org/contact/#feedback .
* (Linux Ubuntu) Under Unity, keyboard shortcuts are not visible in the
Audacity menus. Keyboard shortcuts are visible if you install the classic
GNOME Flashback interface or under Unity if you open Audacity with the
UBUNTU_MENUPROXY=0 environment variable. Audacity compiled from source
will ship with src/audacity.desktop.in set to UBUNTU_MENUPROXY=0 but it
will remain up to distributions to use this desktop file.
Changes in version 2.0.6:
* Interface:
* Redesigned, searchable Keyboard Preferences with Tree, Name and Key views.
* Edit Menu: "Cut" and "Delete" are now in the top level of the menu.

Note: the previous "Snap To On" keyboard shortcut will no longer work.
* "Snap To" settings are now independent for each project.
* Effects:
* Truncate Silence: redesigned with simpler option "Truncate Detected
Silence" to shorten to the specified length without compressing silence.
* VST effects: New "Settings" dialog lets you specify buffer size (for
faster processing) and enable buffer delay compensation (to prevent
inserted silence). Compensation may cause a crash in a few plug-ins.
* VST effects now support standard FXP presets.
* LV2 effects are now supported on all platforms (textual interface only).
* Import or export using FFmpeg now requires FFmpeg 1.2 or later (or libav
0.8 or later). For recommended downloads of recent FFmpeg please visit:
http://manual.audacityteam.org/o/man/faq_installation_and_plug_ins.html#ffdown .
* New Tamil translation (largely complete).
* (Windows) FLAC exports can now exceed 2 GB in size.
* (OS X) Easier Audacity installation using the DMG: drag the Audacity folder
to the /Applications shortcut.
* (OS X) Audacity 2.0.6 will not officially support OS X 10.10 Yosemite when
released (in particular, Apple Audio Units may not open in Audacity).
* (Linux) Self-compiled builds of Audacity now search for system LADSPA
effects in /usr/lib/ladspa.
Bug fixes:

* (OS X and Linux) Nyquist effects ran much more slowly than on Windows.
* Click or drag on the Timeline after Loop Play continued to loop.
* Transcription Toolbar did not play slower than 0.1x speed.
* (Linux) Audacity did not build if python 2 was not available.
* Projects did not reopen correctly if they contained tracks having
2^31 samples or greater of audio (just over 13.5 hours at 44100 Hz).
Changes in version 2.0.5:
* Tracks Menu:
* The separate commands that aligned track start or end with the cursor or
with selection start are combined into "Cursor/Selection Start" commands.
* "Align and Move Cursor" renamed to "Move Selection when Aligning".
* Label Tracks:
* Labels Editor now allows empty labels to be saved on closing the editor.
* TAB and SHIFT+TAB when the label track has focus now always move forwards
or backwards respectively to the nearest label.
* (Windows) On a very few machines, the Windows WDM-KS low latency audio host
introduced in Audacity 2.0.4 caused Audacity to hang or the computer to
crash. WDM-KS has been removed from 2.0.5 until it can be safely enabled.
* (Windows and OS X) Screen reader improvements for Install VST Effects dialog.
* (OS X) Audio Unit plug-ins detected by Audacity on launch are now not loaded
until chosen from the Effect menu. This should speed up launch and avoid
crashes at launch due to misbehaving Audio Units.
* (Linux) Update to PortAudio r1910 fixes memory and other bugs under ALSA.
* (Linux) Applied fix for wxGTK 2.8.12 bug which resulted in loss of Audacity's
menu bar (or visual corruption under Unity) on Debian-based systems.
Bug fixes:
* Shaped dither was corrupted and too loud on all stereo exports except FLAC.
* Keyboard Preferences: some Edit and Align commands for different sub-menus
showed the same name.
* Recordings stopped with "Stop and Set Cursor" shortcut could not be undone.
* In locales that use comma for decimal separator:
* Text boxes with slider in Nyquist effects only produced whole numbers
when using comma to enter a fractional number. Text boxes without
slider still have this problem.
* Built-in generators produced silence after running a Nyquist effect.
* (Windows) When first changing to Windows WASAPI host, the input volume slider
in Mixer Toolbar was enabled when it should have been permanently disabled.
* (Windows) On some machines, launching Audacity then recording from the current
Device Toolbar input would not record until the input was reselected.
* (OS X) Frequent crashes occurred on importing audio files on some machines.
* (OS X) Files did not open using Finder "Open with", double-clicking the
file or dragging the file to the Audacity icon.
* (Linux 64-bit) Fixed a crash when using Equalization.
* (Linux) It was not possible to open an effect or other dialog then navigate
through the dialog using TAB.
* (Linux) The Play shortcut did not play a read-directly WAV, AIFF or FLAC
import if the warning for importing uncompressed files appeared.
Changes in version 2.0.4:
* New "Reverb" effect to replace GVerb, based on the original "Freeverb".
* New View > Go to Selection Start and Go to Selection End commands.
* New "Align End to End" command to append existing tracks to each other.
* Change Tempo now supports fractional BPM.
* Plot Spectrum now supports FFT sizes up to 65536.
* WAV files now support "Album Title", "Track Number" and "Genre" LIST INFO
tags and also support ID3 tags.
* Handle a bug in older iPods or some OS X applications that cause them to
refuse AIFF files whose metadata contains an uneven number of characters,
* (Windows) Added support for "Windows WDM-KS" host which can provide very
low latencies if you reduce "Audio to Buffer" in Recording Preferences.
* (Windows Vista and later) You can now record computer playback by choosing
the new "Windows WASAPI" host in Device Toolbar then a "loopback" input.
* (Windows and Mac OS X): VST scanning dialog now replaced with a dialog
for choosing which VST effects to load.
* (Linux) CTRL + ALT can now be used to smooth samples in Draw Tool.
* Modules Preferences replaced with a dialog on launch of Audacity
enabling you to choose which modules to load.
Bug fixes:
* Keyboard Preferences: Shortcuts for Generators, Effects and Analyzers
were not exported. All imported shortcut changes were discarded.
* Equalization curves were corrupted in Graphic EQ mode after switching
to/from Draw Curves or after running the effect then reopening it.
* Change Pitch displayed corrupted values when reducing pitch or editing
"from" Frequency. Detection was very inaccurate at high sample rates.
* Bass Boost no longer clips if the track contains 32-bit audio.
* Auto Duck was excessively slow on older machines.
* (Windows) Exported MP3 comments tags were not seen by Windows programs.
* (Windows and OS X) Audacity crashed if you used system quit before
file import was complete.
* (Linux) Equalization crashed Audacity if the XML file was corrupted.
* (Linux) When configuring effect parameters in "Edit Chains", "Preview"
(not intended to be functional) caused a crash.
* (Linux) LICENSE.txt and README.txt were wrongly installed in
/usr/local/share/doc instead of /usr/local/share/doc/audacity/ .
* Accessibility: ENTER did not toggle selectedness of a label track unless
a label was selected.
* Numerous other interface fixes.
Changes in version 2.0.3:
* The SoX Resampler library (libsoxr) has replaced libresample in
Audacity releases, offering both higher quality and greater speed. .
* Time Tracks new features:
* "Set Range" now changes only the range of the Time Track,
preserving the pitch/speed set by any existing warp points.
* Vertical scale added with options for linear and logarithmic
display and interpolation.
* Upper and lower speed limits will now be remembered when saving
and reopening a project in 2.0.3. Warp points in projects saved
by previous Audacity versions will be correctly restored in 2.0.3.
* Warp points saved in a 2.0.3 project will be preserved if opened
in previous versions but playback and display will be incorrect.
* New effects:
* Studio Fade Out (uses a filtered "S" curve).
* Adjustable Fade (accessible effect for creating partial fades
and adjustable fade shapes).
* Bass and Treble (replaces Bass Boost).
* Real sample rates up to 384000 Hz are now supported for playback
and recording in high resolution devices (the maximum is up to
192000 Hz for Windows DirectSound host).
* Labeled Regions in Edit Menu is renamed to "Labeled Audio" and now
allows splits to be placed at point labels. Labeled audio regions
that touch without overlapping are treated as separate regions.
Overlapping labeled audio regions are treated as a single region.
* Compilation: cmake is required in order to build libsoxr.
* New Croatian translation of Audacity.
Bug fixes:
* Crash using Undo whilst time-shifting a track.
* Crash using Repair if the selection extended into an empty track.
* Export Multiple didn't prevent export if there was no audio or
all audio was muted. This allowed export of small invalid files.
* Time Track:
* Loop Play of a speeded-up track inserted silence.
* Playback and rendering was significantly inaccurate, creating
audible and visual glitches.
* Accessibility:
* The mnemonics character "&" was read out by screen readers in
most of the Preferences choices.
* NVDA did not read static text in most dialogs. Text can now be
read by using INSERT + B.
* JAWS and Window-eyes misread the "Duration" control in Silence
Generator.
* Toolbar buttons could not be pressed by ENTER
* Other interface bug fixes.
Changes in version 2.0.2:
* Duration controls when generating at a point now default to
hh:mm:ss + milliseconds format. Selection Toolbar also defaults
to that format on first installation or resetting preferences.
* Toolbars visual improvements:
* "Snap To" in Selection Toolbar now has an explanatory tooltip.
* Device Toolbar tooltips now display the selected device.
* Increased default width of Device Toolbar and Meter Toolbar.
* Improvements and some bug fixes to Nyquist effects, including:
* Delay (new option to prevent duration change)
* Sample Data Export (new "L-R on Same Line" layout option)
* Risset Drum (new "Amplitude" slider).
* Importing a labels file writes the file name to the name of the
Label Track, and exporting a labels file offers the name of the
last Label Track in the project.
* Removed the "Audio cache" option from Directories Preferences
due to frequent crash reports. All data operations will now
be written to disk and not to RAM.
* Removed the FFmpeg "On-Demand" option from Libraries Preferences
(this fixes Audacity not building if configured --without-ffmpeg).
* Compilation: Progress on making the Modules feature mainstream.
Modules can now be individually enabled and disabled in Preferences.
Bug fixes:
* Interface:
* "Retain labels" Interface Preference did not retain labels for
a region that snapped exactly to both label edges.
* Projects did not save the track selected state.
* (OS X, Linux) Timer Record: Interlinking of the Start, End and
Duration controls was broken.
* (Windows) JAWS screen-reader did not read the "Draw curves" and
"Graphic EQ" radio buttons in Equalization correctly.
* Envelopes and Clips:
* Exporting (or any render operation) on a track containing
split lines could create clicks at the split lines.
* Dragging a clip into another track caused a crash if Sync-Lock
Tracks was enabled and there was also a label track.
* Effects and Analysis:
* Normalize could crash if the track name contained "%".
Changes in version 2.0.1:
* Shortcuts can now be added in Keyboard Preferences to items in the
Generate, Effect or Analyze menus, including user-added plug-ins.
* Nyquist Effect plug-ins can now be added to Chains.
* New "Paulstretch" effect for extreme slowdown without pitch change.
* New "Sample Data Export" Analyze effect for exporting a file
containing amplitude values for each sample in the selection.
* New Preference (off by default) to import files On-Demand (without
seek ability) when using the optional FFmpeg library.
* New Preference (off by default) to retain labels when deleting a
selection that snaps to the label without extending past it.
* (Windows installer) New option to reset Preferences on next launch.
* (Mac) Audacity now has excellent compatibility with the VoiceOver
screen reader. For details, please see:
http://manual.audacityteam.org/help/manual/man/accessibility.html#mac .
* CleanSpeech Mode (no longer supported) will not now be enabled
even if it was enabled by an earlier version of Audacity.
* Added Serbian (Latin and Cyrillic) translations.
Bug fixes:
* Interface:
* Selection Toolbar: a value for the previous whole second
displayed if the value was close to a whole second.
* Finding zero crossings could cause the selection to expand into
white space at either side of the clip.
* Clips did not drag to another track if mouse was over a selection.
* Mixer Board: Rendering four tracks resulted in a redundant Track
Strip followed by a crash.
* Imports, Exports and Files:
* Exporting to WAV or AIFF led to a "Libsndfile says" error or
corrupted output due to order of metadata in imported files.
* (Mac) Fixed crashes importing MP3 files on PPC machines.
* (Linux Ubuntu) .Aup files could not be associated with Audacity
(they opened in the web browser instead).
* Effects and Analysis:
* Normalize: Fixed issues where normalization could be to wrong
value if applied with DC offset correction, or if applied to
"read-directly" WAV and AIFF files before On-Demand completed.
* Sliding Time Scale: fixed an audible discontinuity at the
beginning of the processed selection; fixed a serious quality
problem on Linux 64-bit.
* Other miscellaneous bug fixes, including fix to prevent zooming
with mouse wheel or ball scrolling the content off-screen.
Changes between version 1.3.14 Beta and 2.0.0:
* New Interface preference to show the track name in the display (this
is off by default).
* Longer default Playback preference for effects preview and preview
before cut.
* Restored use of Page Up and Page Down to scroll horizontally.
Bug fixes:
* Interface:
* Fixed playback speed and synchronization problems when dragging
clips or tracks between tracks having different sample rates.
* (Windows) Removed a crash risk where shortcuts could be
used to record or import in one project while importing or
exporting in another.
* Imports and Exports:
* Fixed crashes when changing the sample format of read-directly WAV
or AIFF files using the Track Drop-Down Menu.
* Fixed a crash importing MP3 files that had duplicate metadata tags
(this is a bug in current libsndfile which has been patched in
Audacity; MP3 files mislabeled as WAV which have duplicate tags
will still crash Audacity on Linux if Audacity has been compiled
against an affected version of system libsndfile).
* Fixed an issue where excessively high or corrupted sample values in
the audio could corrupt exports from the start of the problem for
the rest of the file, and could corrupt the rest of the project.
* (Linux) Fixed Audacity could not be compiled against FFmpeg
0.7.x and 0.8.x.
* Effects and Analysis:
* Fixed crash on launch when using "Ambisonic Decoders (PC)" VST
plug-ins and other plug-ins that enable additional floating point
exceptions.
* Fixed Plot Spectrum background could be transparent on some machines.
* Bug fixes for Click Track, High Pass, Low Pass and Vocal Remover.
* Chirp, Tone and Silence generators now remember their settings.
* Other miscellaneous bug fixes.
Summary of bug fixes and new features between 1.2.6 and 2.0.0:
* New features: There are dozens of new features in 2.0.0, including:
* Many effects significantly improved, especially Equalization, Noise
Removal and Normalize. Vocal Remover now included plus GVerb on
Windows and Mac. VAMP analysis plug-ins now supported.
* Improved label tracks with Sync-Lock Tracks feature in the Tracks Menu.
Multiple clips per track. Tracks and selections can be fully
manipulated using the keyboard. Many more keyboard shortcuts.
* New Device Toolbar to manage inputs and outputs. Timer Record feature.
New Mixer Board view with per-track VU meters.
* Automatic Crash Recovery in the event of abnormal program termination.
* Fast "On-Demand" import of WAV/AIFF files if read directly from source.
FLAC now fully supported. Added support for optional FFmpeg library
for import/export of AC3/M4A/WMA and import of audio from video files.
Please visit http://www.audacityteam.org/about/features/ for a full
list of features in 2.0.0. You can click Help > Manual (in web browser)
in the program to read more.
* Bug Fixes:
* Labels now accept lower case "z".
* (Windows Vista/7) Pressing Stop after recording could cause a crash.
* (Mac OS X) Fixed shortcut keys activating when typing in file open or
save windows.
* (Mac OS X) Audacity 2.0.0 fully supports Unicode, which fixes an
issue where Audacity could not work with folders having non-English
characters in their name.
* (Linux) Playing existing tracks while recording in mono could cause
recordings to be distorted or low-pitched.
Changes in version 1.3.14 Beta:
* Normalize: Faster processing and improved interface. Left-right balance
in unsplit stereo tracks is now preserved by default, with a checkbox
option provided to process stereo channels independently.
* Spectrograms now allow window sizes up to 32768 and frequencies up to
half the sample rate (the maximum possible).
* Mix and Render now preserves clip length by not rendering white space
between time zero and first audio, and preserves audio before time zero.
To retain silence before the audio starts, generate silence after render.
* Grouped some Edit Menu items into "Remove Audio" and "Clip Boundaries".
* CleanSpeech Mode removed from Interface Preferences (it still runs if it
was enabled in a previous Audacity but can only be turned off there).
* (OS X) Added support for AudioUnit MusicEffects (but no MIDI support).
* (Linux) Set the per-user files directory per the program name set in
configure.
* (Linux) Changed the default location of the Audacity temporary directory
to be in /var/tmp not /tmp, so preserving the directory between reboots.
Bug fixes:
* Interface:
* Excessive delay occurred when typing into labels in long projects.
* Last digit of TimeText controls could not be manipulated in some formats.
* (Windows, OS X) Play and Record shortcuts did not work after clicking in
Device Toolbar.
* (OS X, Linux) Crash occurred if Toolbars were reset during playback or
recording.
* Imports and Exports:
* MP2 files were not importable without FFmpeg library or an import rule.
* Files that could only be imported using FFmpeg imported as noise with
no error message if FFmpeg was not available.
* Files containing PCM audio but an incorrect extension (such as MP3)
caused a freeze.
* Effects and Analysis:
* An empty command could be added to a Chain which then displayed a
Nyquist error message when run.
* Plot Spectrum didn't preserve signal level if multiple tracks were
analyzed.
* Other bug fixes:
* Audacity has been provisionally fixed so that it can no longer create
block files longer than the sample format or project format allows,
and can no longer delete these, which led to data loss. Any overlong
blocks found are preserved but "orphaned", so will appear as silence.
* Orphan block files were wrongly reported if cutting or copying to
the clipboard then reopening the project in the same session.
* Fixed some crashes and incorrect movement of audio when dragging tracks.
* (Windows) Data loss is now prevented when encountering a corrupted
.aup file created in ANSI builds.
* (Linux) Restore building if USE_PORTMIXER is not defined.
Changes in version 1.3.13 Beta:
* Control Toolbar renamed to Transport Toolbar.
* Device Toolbar (on by default) now contains all input and output device
choices, including host and recording channels. Input/output choices are
no longer in Mixer Toolbar on Windows XP or some older operating systems.
New Transport > Rescan Audio Devices menu item to refresh the device list.
* New "Sync-Lock Tracks" feature (turned on in the Tracks menu) to allow
groups of audio and/or label tracks to retain synchronisation when the
track length changes.
* Equalization: New "Manage Curves" dialog for importing and exporting curves.
* Noise Removal: New "Sensitivity" slider to adjust the noise threshold, and
new option to isolate noise.
* New "Extended Import" Preferences for specifying different importers to
open specific file extensions.
* Improved Automatic Crash Recovery with all project changes autosaved.
* MIDI tracks can be vertically zoomed, time shifted and display bar lines.
Note: the channel selection buttons are not available in 1.3.13.
* (Windows and Linux) The window Close button and other system close or
shutdown commands now quit on closing the last window. File > Close now
always clears to a new, empty project.
* (OS X) Simpler installer with top-level "Audacity" folder.
Bug fixes:
* Interface:
* Cutting or copying from a track at a given sample rate into a track
at another rate resulted in speed-changed audio.
* Generating inside a clip could modify the clip length or create
spurious clips.
* Recorded stereo tracks were only half the height of imported or
generated stereo tracks. Imported stereo files had a "1" appended
to the track name.
* Edit > Region Save did not save the cursor position.
* (Windows) Projects crashed when clicking rapidly inside the interface
or when applying repeated effects towards the end of audio tracks.
* (Windows) Some Unicode characters could not be typed into labels,
or caused a freeze using some input methods.
* (OS X) Crash when quitting an empty project window, or when closing the
main project window while a progress dialog was on screen.
* Numerous other interface fixes including Dependencies dialog,
Keyboard Preferences and spurious lines drawn on waveform.
* Imports and Exports:
* Support added for later versions of the optional FFmpeg library up to
current FFmpeg HEAD. This should significantly improve FFmpeg support
on Linux. FFmpeg downloads for Windows and Mac updated to v0.6. This
fixes mono AAC files importing as stereo, though current 0.5 versions
of FFmpeg will still work.
* Both FFmpeg and LAME should now be properly detected even when other
versions of those libraries exist on the system.
* New warning (on by default) for importing uncompressed audio files.
Better error messages when read-directly uncompressed files are missing.
* Imported ID3v2 metadata tags were removed when exporting without the
Metadata Editor appearing (for example, when using an export command
in Chains). Note: As a result of this fix, ID3v1 tags must now be
written by exporting using (external program) and an installed LAME.
* U-Law/A-Law files with WAV headers now use the standard 18 byte fmt chunk,
so should now be recognised by most telephony applications.
* Variable bit rate MP3s exported using "MP3 Files" were larger than
necessary because using the bit reservoir was disabled.
* (OS X) Files imported from iTunes could create invalid characters in the
.aup project file, causing an error when re-opening the project. Note:
An error "reference to invalid character number" will still occur if
re-opening a project created in previous Betas that contains such
characters. To fix the issue, open a back-up copy of the .aup file in a
text editor, turn off word wrap, then in the line indicated in the error
message, remove the string of characters that starts with &# and ends
with a semi-colon (;).
* Other bug fixes:
* Nyquist effects: fixes for crashes, incorrect slider behaviour and better
support for backslashes, double quotes and Unicode characters.
* (Windows and OS X) Processing of VST effects was substantially slower than
in previous versions of Audacity.
* (OS X 10.5 PPC) A first-time installation of Audacity Beta would hang
on launch if VST effects were detected.
* (Linux) Recordings made with the pulse device crashed or stalled when
using overdub and/or software playthrough.
* (Linux) Play-at-Speed crashed at 0.08 speed or lower if Audacity was
configured with libsamplerate.
Changes in version 1.3.12 Beta:
* A hover tooltip is now provided if the Mixer Toolbar input selector
cannot control the system slider for the selected input.

other curves
* Timer Record now remembers last scheduled duration
* Meter Toolbar can now be made much narrower, and so more suitable for
vertical orientation
* New Preferences choice for "System" language which is used on first
run instead of asking user to choose language
* Warning now provided if WAV/AIFF exports are not successfully
completed
* (Linux) Improved icon set in compliance with freedesktop.org
Icon Theme Specification 0.6

folders to disappear from the list, and file filtering was broken
Changes in version 1.3.11 Beta:
* (Windows) Better icon file with higher resolution and transparency
* New SoundFinder plug-in to label regions of audio between silences, so
allowing silences between tracks to be excluded when exporting multiple

exported is fixed.
* Fix corrupt files exported through FFmpeg when metadata included,
(metadata is now exported correctly in M4A files)

Changes in 1.3.0:
New features
The new features in Audacity 1.3 have been grouped into the
following six major categories.
1. Collapse/Expand Tracks
In Audacity 1.3, every track has an upward-pointing triangle at
the bottom of the label area on the left side of the track.
2. Multiple clips per track
In Audacity 1.2, there is one audio 'clip' per track. There is
no easy way to time-shift part of a track without moving the
rest. In Audacity 1.3, you can split a single track into multiple
clips. You can move these clips around between different tracks,
making it easy to construct complex compositions out of hundreds
of smaller audio samples.
3. Selection Bar
In Audacity 1.2, the current selection is contained in a
status bar at the bottom of the window. In Audacity 1.3,
this is replaced by a fully functional Selection Bar, which
displays and controls the current selection (your choice of
Start and End, or Start and Length), and the current audio
position. The selection bar is fully editable - just click
in any field and type to change the current selection precisely.
In addition, many formatting options allow you to view times in
different units, such as samples, CD frames, or NTSC video frames.
4. Improved Label Tracks
Label Tracks are Audacity's way for you to create markings 3
and annotations within your project. In Audacity 1.3, Label
Tracks are much improved, with support for overlapping labels,
and support for modifying both the left and right edge of the
label region just by clicking and dragging.
5. QuickTime and Audio Units on Mac OS X
On Mac OS X, Audacity can now import and audio file supported
by Apple's QuickTime technology. This includes .MOV and .MP4
(AAC) files. Unfortunately encrypted audio files (such as
those from the iTunes Music Store) cannot be imported directly
into Audacity - Apple does not allow this to be done easily
because it would be too easy to circumvent the encryption this way.
Also on Mac OS X, Audacity now supports Audio Unit plug-ins.
Audacity searches for Audio Units in the usual location, in the
system or user's Library folder.
6. Other features
Better performance with large projects
Project integrity check on open
Transcription toolbar
Upload
Batch
Cut lines
CleanSpeech
Changes in 1.2.4:
* The File menu now includes a list of recent files.
* The "Generate Silence" effect now prompts for a length.
* Audacity is now built with Vorbis 1.1, which features better encoding
quality and file compression.
* Dragging sound files into the Audacity window now works on Mac OS X
and Linux, as well as Windows. (Before, it worked only on Windows.)
* The "View History" window can now discard old undo levels to save disk
space on Windows. (This previously worked only on Linux and Mac.)
* "Preferences" command is now in Edit menu.
* "Plot Spectrum" command is now in Analyze menu.
* Opening a project file saved by a later version of Audacity displays
an intelligent error message. Also, trying to import a project file
(instead of open it) displays an intelligent error message.
* Audacity now compiles in Visual C++ .NET 2003.
* Other minor bug fixes.
* New or updated translations: Arabic (ar), Czech (cs), Finnish (fi),
Hungarian (hu), Japanese (ja), Norwegian (nb), Slovenian (sl),
Simplified Chinese (zh_CN), Traditional Chinese (zh_TW).
Changes in 1.2.3:
* Fixed a bug that caused recording to stop or display incorrectly
after about 50 minutes on some Windows systems. (This was partly
fixed in Audacity 1.2.2, but still didn't work on some systems.)
* The Change Pitch and Change Tempo effects have been upgraded to
use a new version of the SoundTouch library by Olli Parviainen,
with better speed and higher quality.
* libsndfile has been upgraded to version 1.0.11.
* Fixed a bug that caused the program to run slowly when using the
Envelope tool.
* Shift-clicking on a mute or solo button now un-mutes (or un-solos)
all other tracks.
* Nyquist plug-ins can now accept strings as input. Also, a "Debug"
button has been added to Nyquist effect dialogs, which allows you
to see all of the output produced by Nyquist, for aid in debugging.
* When the audio file referenced ("aliased") by an Audacity project is
missing, Audacity will now always play silence. Before, Audacity
would sometimes repeat the most recent audio that was played previously.
* VU Meters will now always reset when audio I/O has stopped.
* Fixed a major Mac-only bug that was causing Audacity to crash at seemingly
random times, but especially during audio playback and recording.
* New or updated translations: Italian (it), Hungarian (hu),
Ukrainian (uk), Spanish (es). Polish (pl), Simplified Chinese (zh),
Norsk-Bokmal (nb), French (fr).
Changes in 1.2.2:
* VU Meters added for both playback and recording. Click on
the recording meter to monitor the input without recording.
* Export Multiple - new feature that lets you export multiple
files at once, either by track, or split based on labels.
* Attempt to automatically correct latency in full-duplex recordings.
(This does not work perfectly, and is not yet supported on all
systems. It will improve in future versions.)
* Fixed a serious bug that could cause data loss when you save and
then reload and re-edit an Audacity project containing repeated
or duplicate data.
* MP3 tags dialog will only pop up the first time you export as
MP3; after that it will not pop up again as long as you have
filled in at least one tag.
* You can now add a label at the current playback position - in
the Project menu, with a shortcut of Ctrl+M.
* Clicking on a label now selects all of the tracks, making it
easier to use the label track to recall selections.
* Windows: Fixed a crash in the Time Track "Set Rate" command.
* Fixed a bug that caused problems with recordings over 45 minutes
on some Windows systems.
* Mac OS X: Improved support for the Griffin iMic by fixing a bug
that was causing it to always record in mono instead of stereo.
* Added support for Software Playthrough (listen to what you're
recording while recording it, or while monitoring using a VU
meter) - this makes it possible, for example, to record using one
audio device while listening to it play through a separate device.
* Unix/Linux: Fixed freeze caused by captured mouse when audio
device hangs. (Audacity may not respond, but it will no longer
freeze all of X.)
* Fixed a cosmetic bug that caused improper waveform display if
you tried to open an Audacity project saved on a different
platform (e.g., copying a project from a Mac to a PC).
* Fixed bug that could cause instability when pasting, splitting,
or duplicating a label track.
* You can now change the font of a label track by choosing "Font..."
from the label track's pop-up menu.
* Basic printing support has been added. Currently it scales the
entire project to fit exactly on one page. Try printing in
landscape orientation for best results.
* Mac OS X and Windows: Audacity ships with a newer version (1.0.1)
of the Ogg Vorbis encoder. Vorbis compression will now have higher
quality and smaller file sizes.
* Fix a bug that occasionally caused crashes when applying effects
to split tracks.
* Zoom In / Zoom Out now properly disable when they're not available.
* Fixed disk memory leak in Preview
* Other minor bug fixes and performance improvements.
Changes in 1.2.1:
* The following translations have been added or updated: Finnish,
French, Hungarian, Italian, Japanese, Norwegian, Polish, Russian.
* Fix a bug that could cause data to be lost when pasting audio
from one project into another, after the first project has been
saved and closed.
* Fix a possible crash when opening or resizing the Equalization
window, especially when using large system fonts.
* Don't allow percentages less than -100% in Change Pitch/Speed/Tempo
effects (fixes a possible crash).
* Fix a crash when the temporary directory is not available on startup.
* Correctly load ID3 tags saved in Audacity project files.
* On Linux and OS X, store lockfiles in the temp directory instead of
the user's home directory. This fixes problems in lab environments
where users have restricted or network-mounted home directories.
* Fix a bug that prevented Nyquist effects from running when certain
regional settings were activated.
* Fix a bug in the Quick Mix command that could cause old temporary
files to not be deleted.
* Linux: Fix endianness problems in playback on PowerPC.
* Linux: Fix compilation problem in Nyquist on MIPS.
* Linux: Include a more recent PortAudio v19 snapshot (fixes compilation
problems when building with the --with-portaudio=v19 option).
* Two new Nyquist plug-ins: "Cross Fade In" and "Cross Fade Out."
* Other minor bug-fixes.
Changes in 1.2.0:
* New cross-fade effects.
* Fix problem where samples were drawn in the wrong position
when zoomed all the way in. This caused the drawing tool
to move a different sample than the one under the cursor.
* Don't use id3v2.4 tags, which are not yet supported by
most players. (This was fixed in 1.2.0-pre2, but appeared
again by accident in 1.2.0-pre3.)
* Correctly display translated messages in the status bar.
* When the cursor is on-screen, the Zoom In button now zooms
to the area around the cursor.
* Mac OS X: Fixed audio problems on the Apple PowerMac G5.
* Linux/ALSA: Work around a bug in ALSA's OSS emulation that
caused Audacity's playback cursor to move too quickly.
* Microsoft Windows: The Audacity source code should now
compile out of the box on Windows.
* Many new/updated translations.
Changes in 1.2.0-pre4:
* Fixed problems that could occur when importing certain
non-seekable PCM audio files, such as GSM610.
* Fixed bug that was causing the samples to shift off-screen
horizontally when zoomed in very far and the track had a
time-shift offset.
* Fixed bugs in the new resampler that added noise to resampled
audio on some systems. If you experienced noise when exporting
to a WAV, MP3 or OGG file you may have been bitten by this bug.
* Fixed bug that led to occasional crashes when using the
time-shift tool in conjunction with high zoom factors.
* Dithering is now only applied on export when it is really
necessary (e.g. when converting float samples to 16-bit).
* Files that only contain mono tracks are now automatically
exported to stereo files when they contain tracks which are
panned to the left or the right.
* The Delete key can now be used to delete the current selection,
in addition to the Backspace key.
* Fixed bug where Audacity didn't ask whether to save
changes if you close the project or exit while recording.
* Mac OS X: Supports Playthrough (listen to what you're recording
while recording it) if your hardware device supports it.
* Mac OS X: Audacity is now a package (you can right-click on
Audacity.app and select 'Show Package Contents'). Launch time
has improved significantly.
* MS Windows: Fixed problem that caused Windows XP to use
the short name of a file ("TESTFI~1.AUP"), which led to
problems when the file was later opened again using the
long file name.
* MS Windows: Fixed bug that caused file exports to fail
if the destination directory was the root folder of a
Windows drive.
* MS Windows: Audacity's application information which
is written to the Windows registry now always contains
the full path to the executable.
* MS Windows: Fixed problems in trying to set the Windows
registry as non-admin user, for file-type associations.
* Make sure the "Save" command is enabled after changing
gain and pan sliders.
* Updated translations. Added translator credits to the
"About" window in localized versions.

* Fixed bugs in Unix build system (DESTDIR in locale directory,
choosing libsamplerate instead of libresample)
* Support for LADSPA plug-ins on Windows added, and
three open source LADSPA plug-ins ported to Windows
(GVerb reverb, SC4 compressor, and Hard Limiter)
Changes in 1.2.0-pre2:
* Online help completed. The full manual is nearly complete
and will be posted to the web site for online browsing shortly.
* Audacity will no longer let you do unsafe editing operations
while playing or recording. This eliminates many potential
crashes.
* Fixed ability to cancel Quit button.
* New resampling library, with no restrictions on the maximum or
minimum rate of resampling.
* Audacity now supports LADSPA plug-ins on all platforms, and
supports VST plug-ins through an optional LADSPA plug-in
