Question - OPUS downmixing
I’m using the opus command line tools to process microphone array signals (mostly 8 channel). If I set a bit-rate such that the bit-rate per channel is less than 16kbps then opus begins to downmix. I would like to stop this happening if that's possible but I can’t find any information on why it’s doing this or how to stop it.
Any thoughts/advice? I figured I could process batches of wavfiles with fewer channels but it’s a bit of an awkward solution.
