Common questions
Can a text-and-image post become audio?
The source must actually play sound. TuneTrace does not read static text aloud.
Can I keep only the background music?
No. The recording keeps the video’s combined audio, including speech.
Only record audio you have permission to save. The source app or iOS may restrict recording.
