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.
I say possible because I can't fully test it as my motherboard
audio device doesn't show up in Windows (don't know why yet).
So, because of that and because this "fix" needs a little discussion
amongst the troops, I've ifdef'd it with EXPERIMENTAL_HAVE_DEVICE_CHANGE
and have disabled it by default.
What is does is it sets up a device change listener and performs an
automatic rescan when a change is detected. (That's the part that
needs discussion.)
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.
In r13510 I had neglected to build with all local libraries and some of
them needed attention.
So, I also took the opportunity to work out the locale directory and
how to keep it unmolested as well. As a result, all locales are rebuilt
as expected, but into the "build" directory.
As a bonus you may now test Audacity from the "build" directory and have
Nyquist plugins and message catalogs available (so you can test other
languages again without havint to install).
So, again:
mkdir buildme
cd buildme
../configure
make
./audacity
You may now do:
mkdir build
cd build
../configure
./audacity
And all but one directory will remain unmolested...no more object files
in "src".
And if you look carefully, you'll see that the newly built "audacity" is
copied to the top of the build tree...no more having to use "src/audacity"
to run.
You can of course still do the configure from the top and get all of the
objects strewn about the tree.
I still haven't figured out how to keep the locale directory from getting
soiled. I'm not really sure there's a way around it really.
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. ;-))
