A. 1. Ensure that you are not running other resource-intensive apps while recording, as this can cause lag. Close unnecessary apps. 2. Check your storage space. Go to Settings > General > iPhone Storage and ensure you have enough free space. Low storage can affect performance. 3. Try recording in a lower resolution or frame rate if the app allows it, as this can reduce the processing load and help keep audio in sync.

B. 4. If the problem continues, try recording shorter clips instead of long sessions to see if that helps maintain sync.
