Given a mono audio CMSampleBuffer with one channel, how do I create a new CMSampleBuffer which has two channels and whose other channel audio samples are duplicate of the other channel? In other words, I need to create stereo from mono audio.

do you want interleaved or non-interleaved stereo? – Rhythmic Fistman Mar 11 '21 at 14:43
