Audio ducking effect when two users speak at the same time

[imchamaratsl]

Description:
I’m working on an audio-only 1:1 meeting application using Chime SDK v3.

Scenario:
User1 = main speaker
User2 = listener (but can also talk)

Problem:
When both users speak at the same time, user2 stops hearing user1 clearly as user1's voice is getting ducked(can hear but at a low volume) and user2’s own mic input takes over at full volume.

Question:
I found out that we can work on something with using audio transformer but Im already using voice focus to reduce background noice.

Is there a recommended way to handle this scenario, so that user2 continues to hear user1 even while user2 is speaking loud?

Any lead would be highly appreciated !

I am not sure how you are setting up the application, but suggest taking a look at the https://github.com/aws/amazon-chime-sdk-js/tree/main/demos/browser and try to reproduce this issue.

If you are testing locally with two local users then that should be expected behavior or you can see audio running into echo. I tested the demo app locally on two tabs and speaking into the meeting without muting anyone kind of gives the same experience.

Have you tested deploying your application and doing the same tests where User1 is local (you) and the User 2 is someone who has joined as remote attendee into your application?
