Several other issues were also fixed (hopefully ;-)).
This is a major change to accelerator handling and keyboard
capturing. Menu shortcuts, non-menu commands, label editing,
navigation, and basically anything else were you might use
the keyboard should be thoroughly tested.
It had been causing problems in Unity for a while now and they
were missing on OSX as well in wx3. So, the old menu Open/Close
method of hiding has been removed and replaced with an event
filter/monitor which looks for wxEVT_CHAR_HOOK events to pass
key events to the handler that has the keyboard captured.
... miscellaneous direct uses of ZoomInfo::zoom to test and set zoom level.
This includes all the remaining assignments to it.
But moving TrackInfo::PositionToTime and TrackInfo::TimeToPosition into
ZoomInfo and using them is needed to eliminate many more uses.
Also #if'd out the unused AudacityProject::OnZoomToggle().
This changes the autosave XML file to a binary representation
during writing to speed up autosave processing. A lot of the
time used during autosave is a result of having to convert and
print all of the values to the XML file.
Writing the same information, but in binary format, reduces
all of that to just the bare essentials and the actual write
I/O.
During recovery, the binary file is read and converted to
the real xML representation and processing happens as it
did before.
It is a noticeable difference with very long or many tracks.
The included fix has to do with append recording.
Say you have 3 tracks and you want to append recorded audio
to the middle track. Sometime later Audacity crashes and
upon recovery, the recorded audio is actually appended to
the third track, not the second one.
This fixes that by adding an "autosaveid" to each track as
it is written to the autosave file. The same ID is written
to the recording recovery appends to the autosave file.
Then, during recovery, the IDs are matched up and the audio
gets appended to the proper track.
These autosaveid attributes are only present in the autosave
file and not in saved project files.
In particular, use an options structure for AudioIO::StartStream to simplify
calls
ControlToolBar::PlayPlayRegion also takes that structure as an argument, and a
SelectedRegion instead of two times
And other changes
This brings the builtin, LV2, and VAMP effects inline with the
Audio Units, LADSPA, and VST effects. All effects now share
a common UI.
This gives all effects (though not implemented for all):
User and factory preset capability
Preset import/export capability
Shared or private configuration options
Builtin effects can now be migrated to RTP, depending on algorithm.
LV2 effects now support graphical interfaces if the plugin supplies one.
Nyquist prompt enhanced to provide some features of the Nyquist Workbench.
It may not look like it, but this was a LOT of work, so trust me, there
WILL be problems and everything effect related should be suspect. Keep
a sharp eye (or two) open.
A 4hr track used to take about 20s to cut a few samples. This is now significantly improved, to around 3s. Leland did this by
(a) moving the size calculation to when we examine the undo history, so it isn't slowing down the edits.
(b) in size calculation, using sizes that are cached rather than going to disk to find the sizes.
(c) writing the autosave file which is to an FFIle to a string first, i.e. using XMLStringWriter as a buffer for XMLFileWriter.
Step (c) may also make autosave marginally safer, as the risk of a partially updated autosave file is reduced.
This should correct the crash and will also correct
the problem where one project's playback/capture was
being metered in another project if multiple projects
were open.
Warning...this required a small hack that allowed updating the
menus even if the toplevel frame is not the project window. This
is because with the active frame actually becomes the effect dialog
and UpdateMenus() bailed if it wasn't the project frame.
This should be removed when we get multiple effect support.
These are mostly under an EXPERIMENTAL_ #ifdef. Also has a change for the prompt string for preferences so the displayed keybinding is adjusted when in multitool mode.
Current options:
Publisher: name (the closest to what we have now)
Name (doesn't include the publisher, just a straigt up alpha sort
Publisher (creates submenus based on the publisher)
Type (creates submenus based on the type, VST, Nyquist, etc.)
And the Linux method of creating submenus based on number of items
is available to all and you can choose how menu you want per submenu.
I had to bring this back since I'd removed it when for the new effects
and I figured why limit it to only Linux...
Check it out in Preferences (effect page).
You'll also notice that the effects page is starting to talk about
plugins. That will progress further (baby steps) so bare with me
for just a bit more.
I've made it where you can enable and disable via experimentals:
EXPERIMENTAL_REALTIME_EFFECTS
EXPERIMENTAL_EFFECTS_RACK
You will notice that, as of now, the only effects currently set up for
realtime are VSTs. Now that this is in, I will start converting the
rest.
As I start to convert the effects, the astute of you may notice that
they no longer directly access tracks or any "internal" Audacity
objects. This isolates the effects from changes in Audacity and makes
it much easier to add new ones.
Anyway, all 3 platforms can now display VST effects in graphical mode.
Yes, that means Linux too. There are quite a few VSTs for Linux if
you search for them.
The so-called "rack" definitely needs some discussion, work, and attention
from someone much better at graphics than me. I'm not really sure it should
stay in as-is. I'd originally planned for it to be simply a utility window
where you can store your (preconfigured) favorite effects. It should probably
revert back to that idea.
You may notice that this DOES include the API work I did. The realtime effects
were too tied to it and I didn't want to redo the whole thing. As I mentioned
elsewhere, the API stuff may or may not be very future proof.
So, let the critter complaints commence. I absolute KNOW there will be some.
(I know I'll be hearing from the Linux peeps pretty darn quickly. ;-))
This relies on three new nyquist scripts to actually do the editing. The peak-snapping code in FrequencyWindow has been extracted into a new class, SpectrumAnalyst, to provide peak-snapping in spectrogram too.
This change is believed to be a direct refactoring that does not change functionality. It paves the way for more complex kinds of selection, such as selections involving frequency as well as time. It also reduces risk of left and right edges being swapped in future code using SelectedRegion, as the default is to swap on assignment if needed.
This is part 2...
Improve performance of selection via Selection bar
This provides a similar type of speed up when selecting with the keyboard via
the Selection toolbar.
This is part 1...
Provides some relief to the selection "hang"
This patch adds the ability for the keyboard based commands (like cursor left,
extend selection right, etc.) to know when the key has been released.
When the patch is applied the current state is saved only when the key is
released and not every time it repeats.
Here's an example of the difference it makes.
This video show the selection "hang", but also watch the CPU usage. All I'm
doing is pressing SHIFT+RIGHT ARROW.
http://youtu.be/tdMntDwGSkM
This one is the same thing bug with the patch applied. Notice that the
selection "hang" no longer occurs and look at the CPU usage!
http://youtu.be/EpXNsQ4Cky0
Make Snap To project specific
This makes the Snap To setting in the selection bar project specific. Changing
it will no longer affect other open projects.
The state is saved to audacity.cfg when the checkbox is changed. This means
that the next project window to open will start with the new value. (As it
should be).
