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.)
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.
1. Put the new files at the proper level of the Solution Explorer tree.
2. Fix a tiny tiny inefficiency in RotateHistoryWindows().
3. Do not use leading zero-padded windows when gathering statistics.
4. Hamming windows are in the advanced menu of choices, following Federico Miyara's suggestion.
* Removed duplicate paragraph about instructions for Cygwin.
* Restored Leland's added hyphens for headings. :-)
* Reduced STEP 1 to be less redundant, and to only link to wxWidgets.org, rather than the places they are currently storing downloads, which also reduces their version numbers that we need to maintain.
* Step 2.2: Changed remaining ref to 3.0.2 back to 2.8.12.
* Step 2.3:
** reordered the first two paragraphs, so you get the warning about pht.h before getting instructions that say "Build" (and changed them to be about build configuration, not actually doing the build).
** Added information about "audacity-src\win\wxWidgets_additions\window.cpp" to avoid editing the file.
** Restored the paragraph about the 5 core wxWidgets libs we use. Saves build time, and without that paragraph the subsequent "Because of dependencies..." makes no sense -- the dependencies are specified by those 5.
* Step 4:
** Restored the steps 4.1 - 4.8. Good to have, for those who don't already know how to do it this way.
** Restored the instruction about how to alternatively set WXWIN via cmd.exe, and made it explicit that's what it referred to. For lot of devs, that's easier.
* Step 5.3: Removed refs to LAME and FFmpeg, per discussion on -devel.
* typos and rewordings
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.
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.
I've added another project to the Audacity solution called
wxWidgets-2.8.12. And updated the compile.txt file with
instructions on how to build everything.
It automatically copies our setup.h and the fixed window.h
to the proper locations in the wx build tree.
It uses NMAKE to build wxWidgets using the makefile in the
wx tree. (No, I did not try to duplicate the wx project
files. ;-))
Give it a try. I think you'll be surprised how easy it will
be for new users.
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. ;-))
