Conference Speaker Audio Test

How can I test speaker audio for multiple participants as separate instances in a single multi-tab browser session? Is this even possible?

Here's a screenshot of what I mean:

In this test case, the conference is joined by 3 different participants (3 tabs opened to `index.html` on local server in Chrome 95; incompatible with Firefox 91+ & Brave). Active tab is Marcia Brady. Ideally, only Marcia should be speaking, but the speaking statuses for all three participants return true cause audio input from a single mic source can't be isolated.

Same result when joining the conference from two different browsers, except in Firefox trying to turn on the camera throws a startVideoForPeer NotFoundError: https://challengepost-s3-challengepost.netdna-ssl.com/photos/production/software_photos/001/734/069/datas/gallery.jpg

Any way to test the app without multiple devices?

    Great question! Testing conference calls generally requires multiple users.
    TLDR: host the app or use something like ngrok to tunnel to your local server and invite teammates, friends and co-workers to join in on a call.

    The simple answer, is No; as you can't easily test and simulate a conference call on the same machine in the same browser or multiple browsers.
    This is not a limitation our our APIs, but of the way the operating system and the browsers works with audio input devices. You could create additional virtual devices (Search: software audio patch or virtual devices) and then implement our mediaDeviceService to enumerate all the devices on your system; then choose a different one for each - but it's still problematic because of the close proximity of the sound if you don't use headphones for example.
    See this doc:
    https://docs.dolby.io/communications-apis/docs/js-client-sdk-mediadeviceservice
    to enable the ability to choose which device to use for each browser
    (wear wired headphones without mics)

    Hm, that sounds interesting. I'll look into virtual devices.
    Thanks for your quick response ☺
