c++ - Hardware accelerated audio decoding with OpenAL -

-

is possible use iphone's hardware accelerated decoding of mp3s , aac when using openal library?

i suppose there 2 possible approaches if possible.
iphone specific openal extensions.
iphone apis decode audio raw bytes.

i have 2 specific use cases.

  • completely decode short sound bite.
  • piecewise decode larger sound file can streamed openal rather loaded @ once.

update

boy! no one's got answer this? apple's nda stiffle these kinds of questions? what's going on? surely else using openal has wanted better audio performance.

there @ least 1 hardware (or hardware assisted) decoder in iphone device models. can accessed convert mp3 , aac files raw pcm bytes using audio queue services api. thence can process bytes or send them openal.

(assuming mingw) i'm still trying handle on c++ stuff, after reading coun...
