VoiceFocus is unusable in the demo due to low volume#1059

What happened and what did you expect to happen?

Install the browser demo.
Expected behavior: noise reduction doesn't affect the volume.
Actual behavior: Enabling VoiceFocus lowers the volume to uncomfortable levels.

Have you reviewed our existing documentation?

Reproduction steps

  1. Install and run the official amazon-chime-sdk-js demos/browser demo, unmodified.
  2. On the "Join a meeting" screen, open "Additional Options" and enable "Allow Voice Focus" and "Use Echo Reduction", then close the dialog.
  3. Enter a meeting title and your name, click "Continue", and allow microphone access.
  4. On the device-selection screen, leave "Add Voice Focus" off, pick your microphone, and join. Have a second attendee join the same meeting on another desktop browser.
  5. Speak at a steady level; the other attendee hears you at a normal volume.
  6. Turn on the "Add Voice Focus" toggle. This is the moment the volume drops: your audio input is switched to the Amazon Voice Focus device.
  7. Speak again at the same level; the other attendee now hears you at an uncomfortably low volume.
  8. Turn "Add Voice Focus" back off; the volume returns to normal.

Add any other context about the problem here.

  • This is an official demo. It is supposed to work well within the documented limitations of web browsers. The volume level problem is not documented anywhere yet.
  • The VoiceFocus manuals describe that VoiceFocus interacts poorly with built-in browser gain control, so the latter must be turned off through a flag. But the demo doesn't turn it off, which is a defect -- the demo is supposed to follow all the recommendations. We tried patching the React components (which don't expose the necessary AGC interfaces) to turn AGC off, but it didn't help with the low volume.
  • We liked how amazing VoiceFocus was in the Chime native apps. So this is unlikely to be an underlying VoiceFocus model deficiency. It's more likely either a browser/OS audio stack problem, a Chime SDK defect (it misconfigures the browser), or a demo defect (there is a correct way of turning AGC off, after which VoiceFocus starts working).
