## Tune inline, or as a standalone

Most tuners force a context switch: stop your session, open another app, tune, come back. Tuner AUv3 runs as an Audio Unit extension so you can drop it on a track in AUM, GarageBand, Cubasis, or Loopy Pro and tune without leaving your host. Need it outside a session? It also launches as a standalone app.

## Calibration that matches your session

A440 isn't the only right answer. Whether you're matching a historical instrument tuned to A=432, sitting down with a piano at A=442, or playing along to a record at some other reference, the calibration slider (A=430–450 Hz) lets the tuner agree with the rest of the room instead of fighting it.

## The detection engine

The pitch detector runs in the audio render path with the host's real-time priority, so it tracks what you actually play — plucked notes, sustains, and bends — without the lag and flutter you get from tuners that poll on a timer.

A high-precision chromatic tuner that runs as an iOS and Mac AUv3 plugin or standalone app.

Detects any pitched note — not limited to standard guitar tunings — and reports cents off in real time.

Chromatic tuning

Play a reference tone for any note so you can tune by ear or check your instrument against the app.

Reference tone generator

Hear your instrument while tuning without distracting round-trip delay, so it works live, not just in practice.

Low-latency passthrough

Stable, responsive detection that tracks plucks and sustained notes without flutter.

Real-time pitch detection

Calibrate the reference pitch from A=430 to A=450 Hz to match historical temperaments, alternate tunings, or another instrument in the room.
