Your question

I want to add a 2 second audio delay to the recorded video on iOS.

I built a prototype using AudioCaptureSource.Manual and Unity's Microphone class, but Unity's Microphone.Start has a bug where you cannot listen to music in the background while using it.

Using AVProMovieCapture's AudioCaptureSource.Microphone does not have this bug.

I have submitted a bug report to Unity, but I'm not confident it will be addressed anytime soon.

I believe my only option is to reimplement Unity's Microphone class from scratch, and avoiding whatever they did that causes external audio to pause. Before I embark on that journey, I wanted to post a question here to see if there's any way of adding a manual, 0-2 second delay when using AudioCaptureSource.Microphone.

I have reimplemented Unity's Microphone class, but there is an additional Unity bug: UnitySetAudioSessionActive pauses externally-playing audio, and without calling it, Unity audio doesn't play.

I have opened bug report IN-77137 with Unity, but for now, I don't think there's anything AVProMovieCapture can do to work around this issue.
