I am unfamiliar with a planar audio
format. I had someone offline state audio is stored in an interleaved format.
I now understand how that works, as I did
not have this understanding before.
I thank you very much for helping my
understanding of how the data is presented.

I’ve been going through the documentation and
something is not clear to me. When using
ExtAudioFileRead to read from a file into a buffer, how do
you separate the left channel from the right?
I am working to read a stereo wav file into memory but as I
read it, I am reading the file into a single buffer.
I’ve been unable to see where you would read the left
and right channels. I looked at AudioFileReadPackets
also, since I wish to read the file into memory but may not
wish to read the entire file into memory. Unfortunately,
I seem to have encountered the same issue of not being able
to see how to separate the left from the right since
there is only one buffer.
Usually, audio is stored using an interleaved format.
If you want planar audio format, you have to tell it explicitly by
setting the client stream description property of your ExtAudioFile.
