Firstly, thanks for your work on what is really a great project. Can we set stereo=1 in the SDP and also the bandwidth constraint? That would make it ideal for this use case. For music quality webRTC you need 3 things: disable audio processing, stereo=1 in the SDP and a way to limit bandwidth usage so it doesn't saturate the available bandwidth and create errors. Disabling video is also really the best thing to do when recording for this reason (bandwidth saturation), and also Chromium will give you much superior experience. Safari and Firefox isn't quite there yet: Safari can't let you choose your output device and lacks some other useful features, and Firefox doesn't yet seem to allow stereo Opus, maybe that's changed since I tested. Microsoft Edge is now Chromium so you're good to go.

Firefox has supported stereo opus for a very long time (four years at least?). We know it works, it's used by medical professionals for their job and they wrote a message a few month thanking us for this feature, that doesn't seem to work on other browser (according to them, but I see tickets open on chromium). Of course all the chain has to be stereo, that goes without saying: input signal is stereo, negotiation has been done in stereo, having enough bandwidth is important (otherwise opus goes mono), and then playback has to be on stereo hardware (but that's the easy part).
