Every track at your A

RePitch re-tunes your own recordings in real time, without touching the tempo. Set the A of your instrument, and it detects the A of every track and matches one to the other.

RePitch’s Tuning screen: your A at 442 Hz, the reference presets, the staff and a transposition of +3 semitones.

Hear your A

440 Hz

Frequency, from 392 to 465 Hz

Baroque ensembles play at A 415 Hz, the modern orchestra at 440. RePitch brings every recording to the A you choose.

How it works

Your A

Choose the A of your instrument, from 392 to 465 Hz in steps of one hertz: 415 for Baroque, 432, 440, 442, 443. It applies to every track, along with transposition in semitones and fine tuning in cents.

The reference A of 442 Hz selected on the Tuning screen.

RePitch’s Library with the imported tracks and, next to each one, the A detected in that track.

The track’s A, detected for you

Every recording has its own tuning. RePitch detects its A, so you never have to hunt for it, and works out the difference between the track and your instrument on its own.

Just for this track

If a track needs different tuning, open it in the player and give it semitones and cents of its own. Every other track stays on your global tuning, and this one will be just as you left it the next time you open it.

The player for a track with its own settings: its detected A of about 432 Hz (uncertain), transposed +3 semitones and −12 cents.

Tools for practice

Playlists for lessons and rehearsals: Build your setlist once. Every track carries its own tuning, so one tap and it plays just the way you need it.
Metronome: The click is generated inside the audio engine, sample by sample: no lag, no drift.
Tuner: It uses the microphone only while it is open. The moment you close it, the microphone switches off.
Your settings, safe and sound: Search your library in an instant. And with one tap you save a copy of your settings to iCloud Drive or Google Drive, to find them all again on a new phone or tablet.
