Audio Mirror Support

Real-time audio from your Mac to your iPhone.

Quick start

Install Audio Mirror on both your Mac and your iPhone.
Make sure both devices are on the same Wi-Fi network.
On the iPhone, grant Local Network permission when prompted.
On the Mac, grant Screen Recording permission when prompted (used for system audio capture only — no video is recorded or sent).
Open Audio Mirror on both. Tap the other device from either side. Audio starts streaming.

Common questions

The devices don't see each other.

Most common causes:

Both must be on the same Wi-Fi network (not one on cellular and one on Wi-Fi).
iPhone needs Local Network permission: Settings → Privacy & Security → Local Network → Audio Mirror ON.
Mac needs Screen Recording permission: Settings → Privacy & Security → Screen & System Audio Recording → Audio Mirror ON.
Some Wi-Fi networks (guest networks, public hotspots) block peer-to-peer discovery. Try a private network.
If you switch networks while running, relaunch both apps.

The audio sounds choppy.

In iOS settings, switch to Low Latency mode for tighter sync, or Low Bandwidth if your Wi-Fi is congested. The latency indicator on the main screen shows the current end-to-end delay.

The latency number doesn't change when I switch profiles.

The latency display includes network round-trip and codec buffering. The biggest factor is codec frame size — Low Latency uses 5 ms frames vs 20 ms for High Quality. Disconnect and reconnect after switching profiles for the change to take effect immediately.

Audio stops when I unplug USB.

Known issue — the network listener doesn't yet migrate cleanly across interface changes. Relaunch both apps and they'll reconnect over Wi-Fi only. Fix planned for a future update.

Why does this app need Screen Recording permission?

macOS does not provide a dedicated system-audio-capture API to third-party apps. The only documented path is ScreenCaptureKit, which Apple categorizes under Screen Recording. Audio Mirror only reads the audio sample buffers; it does not record, transmit, store, or display any screen content.
