​

​

​

​
supportsAudioProcessing
boolean

​
Supported browsers

All other browsers (including legacy Edge, Internet Explorer, and Opera) are not supported. Chromium-based Edge reports a Chrome user agent and is treated identically to Chrome.

​
supportsScreenShare

Screen share initiation requires desktop. Mobile users can view screen shares but cannot start one.

​
supportsVideoProcessing

Background blur and virtual backgrounds are powered by Banuba and require WebGL2. Mobile browsers are not currently supported. WebGL2 must be available — either hardware-accelerated or software-rendered. If only software WebGL2 is available, video effects will still work but may result in lower frame rates. Safari requires version 15.4 or later. Earlier versions (pre-15 and 15.0–15.3) are excluded due to WebGL compatibility issues with Banuba.

​
supportsAudioProcessing

Noise cancellation is powered by Krisp and requires AudioWorkletNode. Safari requires version 17.4 or later. Earlier versions lack AudioWorkletNode support.

​
Known limitations

​
Audio output device selection — Firefox 116–122

Audio output device selection is disabled on Firefox 116–122. These versions shipped setSinkId() with a bug that breaks echo cancellation when used. Fixed in Firefox 123.

​
Local audio level observers — Safari older than 14.1

startLocalAudioLevelObserver() relies on AudioWorkletNode, which is not available in Safari older than 14.1.
