A small latency is better for reactiveness, less so for battery life and stability.
With WebAudio, spec mentions a small audio quantum so we tune the audio renderer accordingly.
For regular audio, we do a different set up but I can see some applications wanting to get low latency for incoming WebRTC audio.

We could look at implementing https://w3c.github.io/webrtc-extensions/#dom-rtcrtpreceiver-playoutdelay so that your application could provide a hint about this.

Can you provide more info on your usecase?
