[Alephmodular-devel] Sound thoughts

[Alexander S. <ast...@it...>]

Because it's 1:30 AM, I'm not going to attempt paragraphs or even 
sentences.

* Upgrading from Carbon Sound to CoreAudio for the Mac OS X sound 
implementation gives us much greater flexibility; enough that we could 
expand the generic API
* CoreAudio supports n-channel sound, surround output (Dolby 5.1), 3D 
effects (see the sample AUMixer3DTest), and other effects like reverb. 
This lets us go far beyond active-panning stereo. It also lets us skip 
most of our sound code, so:
* Split *all* of the sound code up into classes. This is the stuff that 
is still in sound.cpp. For instance, a CSoundSoft3DSpatializer (with 
the current code) and a CSoundCoreAudio3DSpatializer (using examples 
from AUMixer3DTest).
* Also, get rid of the Quicktime code in CMusic_Carbon and restrict 
CMusic to AIFF only, and play it through CoreAudio (see the sample 
PlayAudioFile). This gets rid of the filetype problems.
