- Thread-topic: AudioConverterFillBuffer failure
Hi Bill,
I was under the impression that I need to use a converter because I'm
also resampling and remapping channels. Can I do all this without a
converter?
I've realized that I need to use AudioConverterFillComplexBuffer, since
AudioConverterFillBuffer is deprecated. I have the callbacks working
now, but it crashes after a few rounds.
Thanks,
Curtis

You should let the output unit do the conversion for you... just tell
it what format you are going to give it and it will take care of the
details - no need or benefit to adding your own converter here.
