That is the function that computes the heights of dark and pale blue lines in
the waveform display.
It's not simple but now the flow of control is less strange and it is better
commented.
This doesn't fix or enhance anything, but it might find use later, such as in
a project to adapt the resolution of the display in reponse to slow scrolling
updates.
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
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. ;-))
Correct Sequence::ConvertToSampleFormat() errors resulting in wrong block file sizes, per offline discussions with Martyn and James.
In WaveClip::ConvertToSampleFormat(), distinguish between failure and no change.
Changed deprecated calls to wxArray::Count() to GetCount(),
In Sequence::Blockify(), no reason to call Alloc() if we know we have no samples, so rearranged that code.
