Description

Spatial audio volume of people within 10m is lower on WebRTC than on Vivox.

Reproduction steps

Repro:

  1. Log in 2 users about 10m from each other on a vivox region and converse in spatial chat. Note the volume
  2. Repeat on a WebRTC region and note the volume.

Observed: The other user sounds quieter on the WebRTC region.

Expected: Voice volumes for WebRTC should be close to that of Vivox so people do not need to adjust their volume levels.

Is this an issue in the viewer's mic volume or the server's mixing volume or the viewer's receiving volume?
