They were, but if I change those 32's to SInt16's the whole thing breaks down. In the headers it looks like either would work:
typedef SInt16 AudioSampleType; typedef SInt32 AudioUnitSampleType;
So I changed them all to SInt16s and modified the ASBD:
_fileASBD.mSampleRate = 44100.00; _fileASBD.mFormatID = kAudioFormatLinearPCM; _fileASBD.mFormatFlags = kAudioFormatFlagIsSignedInteger | kAudioFormatFlagIsBigEndian | kAudioFormatFlagIsPacked;; _fileASBD.mBytesPerPacket = 2 * 2; _fileASBD.mBytesPerFrame = 2 * 2; _fileASBD.mFramesPerPacket = 1; _fileASBD.mChannelsPerFrame = 2; _fileASBD.mBitsPerChannel = 16; No errors, but awful sound.
