Sound direction

Direction helps you find where a sound is louder. Calibration maps levels as you turn; then the meter can follow the loudest live heading. It is approximate and depends on your phone's microphones.

Calibration and live tracking

Calibration is a turn that builds a heading map. Afterward the arrow follows the loudest direction that still has a fresh level. Headings expire. With only the direction you are facing, a stationary mono mic cannot place a brand-new sound — the fix is marked stale.

Hot/Cold mode needs no full sweep: it shows Warmer/Colder relative to a recent average, with a heat bar and Radar Ring meter.

Stereo left / right

On phones that expose two distinct microphone channels, Stereo can show a rough left / center / right indication. Many phones mix mics into one channel; when that happens, DecibelDock says so and points you back to Calibration or Hot/Cold. Stereo is not a reliable 360 degree bearing.

Mic info

A Mic info screen lists inputs and microphones reported by Android so you can see what the device exposes. Your body, case and room reflections all shape the result. On-screen note: Direction is approximate and depends on your phone's mics.
