My USB audio interface is a Behringer UMC-1820. I'm working on a 8 channel sound installation where I'm sending mono audio to a specific output of the AI. I've seen a post How to feed 8 speakers 8 different signals using a Raspberry Pi? here where you write to an eight channel audio file using ffmpeg and then play this multichannel audio file.
Due to memory constraints (the amount of mono-files) I would really like to target this mono file to one direct output of the AI. I was thinking to use Supercollider to first read a buffer, then send it to the relevant out. However I would like to do this from the terminal.
