I'm using two connected V2 AudioUnits, a default output unit and a
stereo mixer. My input source is an AudioFile. I'm trying to use an
AudioConverter to convert the file data (interleaved 44KHz 16-bit
2-channel signed integer linear PCM) to the default input format of the
stereo mixer (non-interleaved 44KHz 32-bit 2-channel floating-point
linear PCM). I've managed to figure out how to stop a crash by actually
allocating the right buffer size, but AudioConverter is giving me back
'insz', kAudioConverterErr_InvalidInputSize. The comment in the header
says:
// e.g. byte size is not a multiple of the frame size
This makes no sense to me; my input buffer size is set as
mBytesPerFrame * framesRequested. My AudioStreamBasicDescription (both
the one for the file and the one for the default mixer input) is the
same one passed to AudioConverterNew(). Also, this only happens the
first time through my render proc; the second time through, I get an
access fault exception inside AudioConverterConvertBuffer(). Can anyone
help me?
