Mixing audio sources from n participant and sending n-1 sources as output to each participant

[sampleref]

Hi,

This is actually not an issue, but I was looking for ways to implement how with gstreamer( can be audiomixer) with audio sources mixed from n participants can be used and later from output each participant listens to only audio from other n-1, not the self voice

Its same as in one of the GStreamer issues at http://gstreamer-devel.966125.n4.nabble.com/audiomixer-implementation-for-audio-conference-cancel-user-1-contribution-when-streaming-to-user-1-td4659790.html#a4693565

I came across this https://github.com/matthew1000/gstreamer-cheat-sheet/blob/master/mixing.md#mixing-audio section where I was curious if this above issue can be asked in this forum

Any suggestions on this regard will really help

Thanks
