## What is LagMeter?

LagMeter measures audio latency from output to mic.

Play a test sound through your selected audio output, capture it with your iPhone microphone, and see the latency in milliseconds.

Use it to compare speakers, soundbars, wired audio, Bluetooth, AirPlay, USB audio devices, and other playback routes.

LagMeter is designed for quick, practical latency checks in gaming setups, home theater systems, audio experiments, and everyday listening environments.

Note: Measurements include the full observed audio path, including output, device processing, speaker sound, air travel, microphone input, and iOS audio processing. Results are most useful for comparing setups under the same conditions.
