... Problem with static initialization order of ReservedCommandFlags, caused
wrong enablement of menu items (at least on Mac), such as Plot Spectrum or
Contrast enabled when there was no selection
... and Track::GetOwner() is publicized, so that now you can find the
the AudacityProject, if any, that owns a given Track; this will help eliminate
some uses of GetActiveProject
- There are two new commands: Scrub Backwards and Scrub Forwards.
- These commands appear on the Transport sub menu of the Extra menu.
- The commands have default shortcuts U and I, and are in the standard default set.
- After pressing one of the two keys, playback continues until the key is released. (Note that this means that the command on the Extra > Transport menu can't actually be used for scrubbing as it executes a KeyDown immediately followed by a KeyUp, but the menu items are needed so that the current keystrokes can be seen and changed.)
- Playback starts from the cursor position, or the start of a time selection if there is one.
- The speed of playback is determined by the zoom level. If the zoom level is normal, then the playback speed is one quarter of the normal playback speed. Zooming in (Ctrl + 1), halves the playback speed, and zooming out (Ctrl + 3) doubles the playback speed. There are minimum and maximum playback speeds of one sixteenth, and four respectively.
- You can scrub to the end of the audio, even if there is an initial selection. In other words, scrubbing forwards does not automatically stop at the end of the selection.
- Normally, when one of the keys is released, the position of the cursor is set to the time when the key was released.
- If during the time one of the keys is pressed the left bracket and or right bracket keys are pressed to set the start and/or end of the selection, then when the scrubbing key is released, the change to the selection made by pressing the bracket keys is preserved - the position of the cursor is not set to the time when the key was released.
This implementation is affected by two existing bugs:
1. Bug 1954 - Clicks may occur starting/pausing play-at-speed or Scrub. (See comment 19 and attached image).
2. Bug 1956 - Windows: MME and WDS playback cursor is buffer length ahead of actual audio playing. This means that on Windows, WASAPI is preferable if scrubbing is being used for the accurate positioning of the cursor.
Instead of only when recording (it broke monitoring), now Audacity
will prevent the system from sleeping while any audio I/O is active.
This might be a little strong-handed though and maybe should be a
preference option.
The distribution will be signed and notarized during an "install" build
and is handled by mac/scripts/build_dist.sh.
The wrapper scripts, mac/Audacity.sh, is no longer needed as it's function
has been integrated into AudacityApp.cpp/main().
Initially, all "hardened entitlements" have been enabled since we don't
know which ones plug-ins will need.
On Mac and Windows, system sleep will be disabled when recording starts
and re-enabled when it ends.
Problem: The previous fix (+ possibly later changes) meant that this was working for mono tracks but not stereo. When recording in a new stereo track, the first track in the project became the focus.
The existing code sets the second of the two new tracks to be the focus before the tracks have been grouped into a stereo pair.
Fix: Set the first of the new tracks to be the focus.
... which was redundant with what happens in the yield to idle events in
ProjectAudioManager::Stop.
This removes direct dependency of ProjectAudioManager on ControlToolBar.
And remove another #include we don't need
ControlToolBar, after we make a system to register functions that calculate
necessary minimum widths for status bar fields.
Also let Scrubbing.cpp register its own strings.
Also be sure to size the status field sufficiently for "Playing at Speed".
... Let the window respond to an undo manager event instead, whenever there
is a push or modify
Maybe this makes a few unnecessary redraws that did not happen before. If
that is important, then we should figure out how to put the logic for eliding
the redraw into ProjectWindow, and the extra information needed for the
decision into the events, but not make intrusions in other code all over the
place.
... This also causes a momentary push-down of the stop button, which happens
in ControlToolBar::StopPlaying, really to be visible, as was apparently the
intent.
For instance, when playing, then clicking in the quick-play ruler to restart
the play elsewhere.
... so most calls to ControlToolBar::SetPlay are removed. One remains in
TransportMenus, which will not be problematic for untangling dependencies,
and one remains where the toolbar remakes its own buttons.
But the routines that start and stop the streams, importantly, don't use it.
... not the best thing for the long term, but hidden dependencies on
TransportMenus.cpp are eliminated
Tying CommonCommandFlags again into the big component, which is now 26
... New files, but (almost) empty; don't use the global variable gAudioIO,
but use one of two accessor function names (which are the same function for
now).
AudioIOBase will have fewer dependencies than AudioIO -- in particular, no
dependency on tracks.
It won't include StartStream. It will contain functions to query the
present state of streams, and device capabilities.
