MeetingLocalAudioFrameEvent - STMLink Docs

MeetingLocalAudioFrameEvent receives explicitly subscribed local PCM frames and is registered through MeetingEngine.localAudioFrameEvent. You can extend MeetingLocalAudioFrameSimpleEvent and override only what you need.

Usage notes

This event follows the Engine’s local mic capture pipeline and doesn’t require having entered a meeting; assigning null stops forwarding frames to your app.
Callbacks stay on the SRTC audio capture thread; don’t perform time-consuming operations. Callbacks keep coming only while the ADM is recording.
