I can also confirm that it has an issue running on Firefox. I'm on version 120.0 on Mac Ventura. It's an issue on both the online demo and when running it locally, but it works perfectly fine on Chrome!

I'll try to post any updates I have.

I think this is related to FireFox publishing in stereo by default if the microphone attached supports stereo input. Our backend currently doesn't handle stereo downmix.
