OK. I have reworked my code to use AudioConverterFillBuffer. It does seem to be converting my data correctly.
Now another question: once my AudioConverterInputDataProc returns ioDataSize as zero to AudioConverterFillBuffer, my input proc never gets called again. Is this correct behaviour? Will AudioConverterReset get it going again or does it take a dispose-new cycle?
Thanks,
Harry

There's a limited utility to be gained by using the convert buffer calls
with sample rate converters...
The FillBuffer works fine - you call it with a destination buffer that you
want to convert, then it will call you until you've given enough data to
produce the samples you've requested.
See - /Developer/Examples/CoreAudio/CAServices/DefaultOutput I think is the
path
You can tweak the values that the sin wave calc uses to generate int, 8K
source if you want to validate that this works
