Yep, m4a.  QWERTY slip.

I've looked at scaudiocompress before. Good code. Useful stuff, but no usage of AudioConverterFillComplexBuffer.

If you just change SCAudioFillBuffer to AudioConverterFillComplexBuffer in scaudiocompress (and use AudioConverter rather than scaudio component), it should work, assuming no mix-down is involved. The SCAudio interface is exactly the same as AudioConverter, so the code is still useful for understanding how to use audio converter.

Do you mean m4a?  Yes, use AudioFile api to read it.  Look at the
scaudiocompress sample code (google it).

Is anyone successfully parsing an AAC/m4s audio file (no DRM) with
AudioConverterFillComplexBuffer?

Is there example code anywhere that demonstrates this - using
AudioConverterFillComplexBuffer?

Thank You
