For anyone who is fatigued by web and telecomms audio quality, I highly recommend trying out JackTrip: https://ccrma.stanford.edu/groups/soundwire/software/jacktri...
If you've ever been in a recording studio with headphone monitoring / studio talkback, it's like that. Really intimate.
This project uses RTCDataChannel for audio, which is very neat, but it's a shame that once again audio on the web has to be hacked to perform well.
