2. Changes in version 1.3.14 Beta:
|
||||
2.1 Changes since version 1.3.14 Beta
|
||||
|
||||
Bug fixes for:
|
||||
|
||||
* 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.
|
||||
* Interface: (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:
|
||||
* 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.
|
||||
* Fix 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:
|
||||
* 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.
|
||||
* 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.
|
||||
|
||||
|
||||
Changes and Improvements:
|
||||
|
||||
* 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.
|
||||
* 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.
|
||||
|
||||
|
||||
2.2 Summary of bug fixes and new features between 1.2.6 and 2.0.0
|
||||
|
||||
* 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.
|
||||
|
||||
* 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.
