Audio Stream Modification in Zoom Video SDK

[AliHassan1249]

Hi, I'm exploring the capabilities of the Zoom Video SDK for a custom application. Is it possible to capture the raw audio stream of participants in real-time, process it externally, and then inject or play back a noise cancelled version of the audio in the session? Any guidance on how audio injection works in the SDK would be appreciated!

The SDK is not intended for this functionality since echo cancellation per participant is built in to the software's design. If you are having issues with individual participant audio noise you need to work with each participant to reduce noise acoustically and thru proper noise cancellation settings within Zoom. As an audio engineer just a reminder that you need to keep in mind that you can only ADD audio effects not subtract sound when using audio filters so noise reduction is limited for live audio. Post audio production using iZotope's RX has special functionality (spectral repair) to reduce noises in a recording where each participants audio is on a separate track.
