Screen record with app audio on iPhone — and your voice

Two sources, two levels

There are two things worth hearing in a screen recording: the app — a game's sound, a video's audio, a notification — and you. They arrive by different routes. App audio is handed to the recorder by the system; your voice comes from the microphone. A good recorder treats them as two levels, not one switch.

In Reel, Settings → Audio has both. Turn either down or off, before or during a recording. A demo with app sound and no voice, a voiceover with the app muted, or both together — each is a setting, not a compromise.

Why a recording comes out silent

Almost always one of these:

• The phone's ring/silent switch was on silent. Many apps respect it and play nothing to record.
• Microphone permission was denied on first launch. Check Settings → Privacy & Security → Microphone.
• The app you recorded uses a protected audio path — some streaming apps do — and the system withholds its sound from any recorder. That is by design and no app can override it.
• The mic level was at zero from a previous session. Reel remembers your last levels.

One track or two

Record audio in single track, on by default, mixes mic and app into one stereo track. That is what you want if the recording goes straight to a story or a message.

Turn it off if you will edit. Two tracks let you duck the app under your voice, cut a cough without touching the music, or replace the voiceover entirely. Every serious editor handles a second audio track without complaint.
