I am trying to use the iLBC audio format when recording and playing voice on the iPhone. Core Audio documentation clearly shows this is supported on the iPhone, but the documentation is pretty vague for required parameters for this format. The audio format id is clear - kAudioFormatiLBC.
Also is is clear that there are no flags.
I can't find anything else in the Apple documentation.
I tried to derive the settings from the rfc 3952 which defines this and came up with:
audioFormat.mSampleRate = 50.00; audioFormat.mFormatID = kAudioFormatiLBC; audioFormat.mFormatFlags = 0; audioFormat.mFramesPerPacket = 1; audioFormat.mChannelsPerFrame = 1; audioFormat.mBitsPerChannel = 0; audioFormat.mBytesPerPacket = 38; audioFormat.mBytesPerFrame = 0;
