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.
When building for wx3 on Linux, the backported number validators
and formatter conflicts with the wx3 version because I never
renamed them. Crashes during termination would occur because
the wx3 version and our version had different vtables.
I was thinking that we would just be able to delete the
backported version when upgrading to wx3, but since
we've made Audacity specific changes to them we can't
simply start using the real wx3 versions anymore.
Therefore, I needed to rename then to prevent the crashes.
1) Shell VSTs were completely unrecognized...that is no longer the case
2) All VSTs will now ALWAYS be initialized and cleaned up from the main
GUI thread. I found that some Waves VSTs would freeze Audacity when
initialized in the audio thread and closed in the GUI thread.
3) While realtime previewing, it was possible that the wrong slave
could be used to process new blocks of audio.
4) I found that the Waves AUs don't crash on a real Mac (instead of a
virtual machine), so I removed the "black list" I'd put in just for
them. (Something to do with needing full 3D support I think.)
Anyway, #2 and #3 were quite intrusive, so as much RTP testing as possible
would be a good thing.
This bit the textual mode plain old text based buttons
and retains the bitmap buttons for graphical mode.
It also allowed me to remove the manual accelerator table
building (no access keys in GUI mode) which was a good
thing as I really didn't know if the was gonna work for
non-English keyboards anyway.
If you can believe it, this whole big mess is
just to get localized effect labels back into
the menus.
I sure wish I'd had a little bit more time to
finish up all of the effects. It sure would
be a lot cleaner (code wise).
All:
Export/Import now disabled if the Effect (family) doesn't support it
Options disabled if the Effect (family) doesn't support it
Standarized on "Latency compensation" instead of "Buffer delay compensation"
Correct loading/saving of factory default settings
Fixed "Mannage" to be "Manage"
Removed conditional code since we're keeping the transport buttons
Play bases state on actual playback status
Play no longer monkeys with selection
Play will now start from where it left off IF:
The user stops the playback via the Effect Stop button
If the user wants to restart from the beginning of the selection
then the user can click Rewind while stopped.
Rewind will not go past start of selection (sorry Steve ;-))
If Rewind is clicked while not playing, playback will next
start at beginning of selection.
Fast Forward will stop at end of selection
However, if FFwd is clicked while not playing, it will
put playback at the end of selection and the next time
the user clicks the Effect play button, playback will
continue from the end of selection to the end of track.
Deleting a preset now prompts user to confirm
Button faces should now look a little better
Bypass (should we rename that???) button now grays when disabled
Audio Units:
Corrected all user visible "AudioUnit" strings to be "Audio Unit"
Removed unneeded "Buffer Size" in settings dialog
Only uses latency if user said it was okay
Ladspa:
Added settings dialog to allow control of latency usage
Removed unused "user selectable" buffer size
Only use latency if user wants it
Refresh controls when presets are loaded
VST:
Removed unused "Rescan at startup" setting
Propogate parameter loads to slave effects
Solves the problem of what the "Settings" button should say
by converting it to a bitmap button.
Adds the missing "bypass effect" button.
The Ok/Cancel buttons are now Apply/Close buttons and the
dialog stays open after the apply is done.
Record is no longer disabled when an RTP effect is open as
the RTP effect now monitors when recording starts and disables
its buttons as needed.
Added "Play", "Skip forward", and "Skip backward" buttons.
While the other stuff is required, this last one is in to
get a feel for its usefulness. We'll need to get feedback
on it pretty quickly so we can rip it out if need be.
I've added some of the new plugin stuff to LV2, Nyquist, and
Vamp so that they play better in the new system. They no
longer get bunched in with the Audacity effects when sorting
or grouping the menus. They have not been fully converted
but they should be good for 2.1.0.
Nyquist plugins now include ";author" and ";copyright"
statements.
Added the 4 new Nyquist plugins to the Windows build.
Audiounits are still coming...had to push them to the back
burner to get this other stuff out of the way.
Scanning for new plugins has been improved so that newly
discovered ones will be shown to the user when Audacity starts.
Effects menu sorting has been fixed and improved.
Disabling effect types in Preferences works again and you
no longer have to restart Audacity for them the change to work.
Effect usage in chains works again.
Plugin registration dialog code simplified a bit.
Group names in the pluginregistry are now base64 encoded. I
never really thought about it, but wxFileConfig group names
are case insensitive and since I was using the group name as
the plugin ID, I ran into a conflict on Linux where there
were two plugins with the same name, just different case. (And
they were different plugins.) Hoping all of this will change
when/if the config file gets converted to XML. (wx3 if finally
including XML support)
A fair amount of cleanup of this new code has been done and
will continue as more stuff is converted.
The big thing is the common efffects UI. Right now Ladspa and VST
have been converted to use it and Audiounits will be next. It makes
everything nice and consistent while reducing the clutter in the
dialog.
Other goodies are:
Ladspa effects now show output controls when supplied by the effect
Ladspa effects now work fine as Analyze type effects
Ladspa now has user presets
VST effects dialog is now less cluttered...leaving more room for the effect
Ladspa and VST effects now share a common UI
Ladspa and VST effects are now usable in chains
Ladspa and VST effects now handle user presets the same way
Currently active effects settings automatically saved and reloaded
Can now do numeric range checking on input fields.
And, as always, plenty of critter squashing.
"The dialogs LadspaEffectDialog, LV2EffectDialog and VampEffectDialog receive EVT_TEXT events before the dialog classes are properly initialized. To prevent this, a workaround was already in place, but was only active on Windows. This happens now on more platforms (including GTK). So activate it on the wxGTK with wx3.0, too."
Main effect host processing extended to support generate
effects and sync locked tracks.
Ladspa updated to utilize new generate support.
I'll address Analyze plugins when I get to the SBSMS ones.
Shared and private config changes are flushed immediately.
Cancel button restored to VST and Ladspa dialogs. This
also restores the ESC button functionality.
Current parameters saved with Apply or Ok clicked...not
when Audacity ends.
Ladspa and VST effects with that reports no input and
no outputs are now ignored.
Ladspa effects providing a latency value is now handled.
Ladspa generator effects now use the TimeTextCtrl for
specifying duration.
This also (hopefully) corrects some additional problems in general
realtime support. Particular focus should be given to the handling
of various combinations of stereo, left channel mono, right channel
mono, and true mono as this has been a particularly troublesome
area.
