👋 Hello, team! Hi LiveKit Team, I am working on an iOS app using the LiveKit Swift SDK (v2.10.1), and I want to implement a custom audio track that combines both: Microphone input (user voice) App audio (music, sound effects, etc.) I want to send this mixed audio as a single track to the LiveKit room so that remote participants receive both mic and app audio. I’ve looked at the AudioCustomProcessingDelegate and RoomOptions(audioProcessing:), but I am unclear on the best practice to: Capture the microphone using AVAudioEngine or LiveKit’s default audio Capture app audio (e.g., AVAudioPlayerNode output) Mix them correctly into one buffer Pass this mixed buffer to LiveKit for publishing Could you provide guidance, example code, or recommended approach for implementing mic + player audio mix in a custom audio track on iOS? Thank you for your support. Best regards, Sudhir

hi! sorry for the delay--i'll add it to the team backlog
