Audio channel manipulation

Good day I am expert working with ffmpeg and vlc libraries and have already extended experience developing streaming solutions. Let me know if we can have some chat about this project Thanks

I have experienced to interface audio ,video,graphics etc. , I will make your project within time period.

Hi. I am not familiar with ffmpeg, but I am developing a device that can perform manipulations with 4 audio inputs for 4 audio outputs. This is similar to your idea, but at the firmware level. I will be able to fulfill your task
