Even though this is only a P2, I felt it would be
quite bothersome for the users and might cause some
confusion.
The problem was the the wxLocale was being deleted
before all usage of it was complete. The fix was
to explicitly delete the plugin and module managers.
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).
Audacity maintains a list of effects it has seen in the pluginregistry
to provide scanning for "new" effects during startup. It also uses
this list to determine if existing effects are still valid.
It was using the single "Enabled" setting to keep track of that, BUT
it also used the "Enabled" setting to determine if the user chose to
enable or disable the effect. That doesn't work since Audacity can
ignore the users choice if effects come and go.
So, this change fixes it by adding a "Valid" setting to separate the
two cases.
I added a few assertions just to be safe. Haven't hit
the particular situations yet, but I've only tested less
than 50 or so AUs.
We were missing a few Apple AUs like panners and mixers.
The plugin "installation" dialog sort is reversed on the Mac...weird
Made the effect windows float on top of the owning project window.
Looking for opinions on which method is best.
Needed to redo a bit of code so that effects would work
without the rack in the middle. I wanted to disconnect
it completely as I'm not sure it something that will be
kept around.
During realtime preview, effects will be applied in the
order their dialogs were opened...hmmm...what happens
if they don't have a dialog??? I look into that.
Fixed the focus target for windows when cycling among
active windows as suggested by David B.
Fixed plugin registration if the plugins were located
in the "Plug-ins" folder. I believe this problem may
have played a role in the duplicate menu items.
They now work on Yosemite.
AudioUnits with a custom Cocoa UI now display graphically
instead of reverting to the generic view
The Cocoa version of the generic view is now used when
needed...instead of the Carbon version.
The order of UI preference is Cocoa, Carbon, Generic,
unless force to Generic view user setting.
They now support realtime preview.
They also support dialog resizing as I found many that
scaled nicely (mostly Apple's).
Uses the new Effect format so now supports user and
factory presets.
NOTE: Be VERY critical when testing this as I've
never written Objective-C or Cocoa code
before!
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 characters were a problem on Linux since wxFileConfig was
intepreting them and creating extra (unwanted) groups.
This change will suffice until/if this is converted to XML.
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.
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.
This gets meter type VST effects working again by extending the
The master now maintains his own internal buffers and sums (mixes) all
playing tracks into those buffers. The buffers are then fed into the
VST effect that is presented to the user. This allows the effect to
provide feedback to the user if it support it. Such effects may display
meters or clipping indicators.
Several issues with treading have also been corrected (hopefully ;-)).
These showed up mostly on Linux, but could have happened on the others
as well.
The realtime support is no longer limited to 2 channels per logical
track. Once support for more channels is added, this should be ready
for it.
The rack dialog can now be toggled via the edit toolbar button. It
doesn't stay pressed because the closing of the dialog would have to
be communicated back to the toolbar.
As the rack is updated with new or removed effects or active state
changed, all effects in the active list were shutdown and all effects
in the updated list were initialized. This now shuts down only the
effects no longer in the list and initializes only new ones.
The rack now uses wxBitmapButton instead of Audacity's AButton. The
AButton has a timing issue that prevents it from being deleted while
processing the click event. I looked into it, but gave up and switched
to the wxBitmapButton. Unfortunately, there's a problem with the
wxBitmapButton as well...at least on my setup here. Either the bitmaps
are being scaled or antialiased. Will have to get feedback on this.
I finally figured out why some VSTs didn't seem to do anything in
realtime, at least in my case anyway. I've installed a lot of demo
VSTs and while they work in "batch/offline" mode, some of them will
not work in realtime since vendors tend to remove automation as one
of the demo limitations.
More changes coming shortly...
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. ;-))
