How can I optimize webcam audio and video sync on macOS?
To optimize webcam video and microphone audio desync, you can create an audio offset to resynchronize your video and audio. You can utilize OBS Studio (https://obsproject.com/ )
You can add an audio offset to your Audio Input Capture.
When you set up PW513 as a Video Capture Device and Audio Input Capture, click the gear next to your microphone source and click "Advanced Audio Properties".
In "Sync Offset" add any value to delay your microphone. The values are in milliseconds. About 200 ms for delay value, so you can start with that and add or subtract from there as you go.
