How to use audioConverterFillComplexBuffer and its callback?
I need a step by step walkthrough on how to use audioConverterFillComplexBuffer and its callback. No, don't tell me to read the Apple docs. I do everything they say and the conversion always fails. No, don't tell me to go look for examples of audioConverterFillComplexBuffer and its callback in use - I've duplicated about a dozen such examples both line for line and modified and the conversion always fails. No, there isn't any problem with the input data. No, it isn't an endian issue. No, the problem isn't my version of OS X.
The problem is that I don't understand how audioConverterFillComplexBuffer works, so I don't know what I'm doing wrong. And nothing out there is helping me understand, because it seems like nobody on Earth really understands how audioConverterFillComplexBuffer works, either. From the people who actually use it(I spy cargo cult programming in their code) to even the authors of Learning Core Audio and/or Apple itself(http://stackoverflow.com/questions/13604612/core-audio-how-can-one-packet-one-byte-when-clearly-one-packet-4-bytes).
This isn't just a problem for me, it's a problem for anybody who wants to program high-performance audio on the Mac platform. Threadbare documentation that's apparently wrong and examples that don't work are no fun.
Once again, to be clear: I NEED A STEP BY STEP WALKTHROUGH ON HOW TO USE audioConverterFillComplexBuffer plus its callback and so does the entire Mac developer community.
