| That's right - that's what noninterleaved means: Each channel is treated separately.
It can be a little confusing, because the AudioBufferList structure defines only a single AudioBuffer within it - you have to either allocate space for the buffer list + the extra buffer, or use a struct or something on the stack.
For example, to prepare an AudioBufferList on the stack, to receive kBufferSize floating-point, stereo, non-interleaved samples:
struct { AudioBufferList bufferList; AudioBuffer secondBuffer; } buffers; buffers.bufferList.mNumberBuffers = 2; for ( int i=0; i<buffers.bufferList.mNumberBuffers; i++ ) { buffers.bufferList.mBuffers[i].mNumberOfChannels = 1; buffers.bufferList.mBuffers[i].mDataByteSize = kBufferSize * sizeof(float); buffers.bufferList.mBuffers[i].mData = malloc(kBufferSize * sizeof(float)); }

Sure - I'll post it when I put together a more simple test app.
Curious: were you reading the noninterleaved audio into two different buffers in a bufferlist? That's the thing I can't seem to find any examples of online.
best,
