Audio Units - interleaved vs deinterleaved


  • Subject: Audio Units - interleaved vs deinterleaved
  • From: GW Rodriguez <email@hidden>

Hi everyone, I've been working on developing audio units that have channel interaction.  I know that I can accomplish this by overriding the ProcessBufferLists() function and have done so successfully.

It's my understanding (according to the documentation) that audio units ONLY work with noninterleaved audio buffers as of version 2, yet in the AUEffectsBase.h the ProcessBufferLists() function has support for interleaved buffers.  Does this have to do with version 1 audio units that supported this type of stream format and this is a way of being backwards compatible?  If so, how likely is it that a host is using version 1?  Is there any way to ask the host what version it is using?

Any info on this subject would be greatly appreciated.

- GW
