at this stage i know of no-one working on something. there's 3 parts of an audio
"engine" to look at. 1. loading of formats (eg, mp3, ogg, wav, etc.) in such a
way that its fairly abstract and the code doesn't care how its really encoded.
2. is the audio device output handler - feeding the audio device cleanly,
handling multiple audio devices, perhaps multiple opens for mixing etc. 3. is
the audio mixing and control engine. EG: you want to play a sample but have it
start fast and slow down in speed (and thus lower pitch) with a given envelope.
you may want to string a sequence of samples together. basically programmatic
sequencer or tracker (remember fasttracker2, protracker, soundtracker, etc.)
kind of solves these. it looks a it complex - that's because it can do a lot.
imho with a bit of wrapping into EFL it should solve it entirely. the problem is
no-one has done anything to do stuff with sound yet. so for now it's a DIY area
that we haven't covered :(
