Hey @rohit_zoom

Thanks for your feedback.

We have been supporting the AEC (Acoustic Echo Cancellation) feature for a while now, and you can enable it in two ways:

1. Specify the `backgroundNoiseSuppression` option in the `stream.startAudio` method.  
[AudioOption | Zoom Video SDK for Web - 1.10.8](https://marketplacefront.zoom.us/sdk/custom/web/interfaces/AudioOption.html#backgroundNoiseSuppression)

2. Use the `stream.enableBackgroundNoiseSuppression` method to enable or disable AEC.  
[Stream | Zoom Video SDK for Web - 1.10.8](https://marketplacefront.zoom.us/sdk/custom/web/modules/Stream.html#enableBackgroundNoiseSuppression)

Please note that currently, AEC functionality is only available when `SharedArrayBuffer` is enabled. In the upcoming release, if you enable `audio_compatible_mode` in the JWT payload, `SharedArrayBuffer` will no longer be required.

Thanks
