Recognize chords from any audio. Plus tuner, metronome and live spectrogram. Free, on-device, no ads, no registration.
Bravo Nota is a free, on-device music toolkit for guitarists, pianists, songwriters and music students.
CHORD RECOGNITION FROM ANY AUDIO
Drop in an MP3 (or any audio file) - or hit Record - and Bravo Nota lays out the chord progression on a scrubbable timeline. Switch between the Original, synthesized Chords, and a crossfade. Handles 7ths, sus, slash and altered chords, not just major / minor. Tap any chord to jump straight to it. Quiet recordings are automatically loudness-normalized on playback; a live mic-level meter while you record helps you nail the right input level.
PITCH-PERFECT TUNER
Chromatic plus dozens of instruments and alternate tunings: Standard / Drop D / Open G / Open D / Open E / Open C / DADGAD / Half-Step-Down guitar; baritone & re-entrant ukulele; banjo Open G & Double-C; mandolin, mandola, viola, cello, double bass; 4/5/6-string bass. A4 calibration from 415 Hz to 466 Hz. The pitch detector is accurate to one cent, stable on bowed strings and decaying piano notes alike.
ADVANCED MODE - LIVE SPECTROGRAM
A waterfall spectrogram for when you need to see every harmonic. Two-finger pinch to zoom into any frequency band, drag to pan; one-finger tap drops a crosshair with note / Hz / dB readout. Optional "peak at this time" overlay marks the loudest tone instantly. Switchable frequency grids (scientific notes, raw Hz, classical Helmholtz), two orientations, optional dB SPL with Apple-ResearchKit calibration.
METRONOME THAT WON'T DRIFT
Well under 1 ms drift over a 5-minute click. Time signatures from 2/4 through 12/8 plus custom; 1/4, 1/8, 1/6 triplets, 1/16 subdivisions; per-beat accents (loud / normal / mute); tap-tempo; Italian tempo markings (Grave through Prestissimo); five built-in click sounds including a real vintage pyramid metronome. Plays in the background - leave it running with the screen off.
FULL CHORD LIBRARY
A browsable reference with every triad, 7th, extension, sus and slash chord across all twelve roots. Each chord ships with a piano keyboard view (highlighted notes) and a guitar fingerboard that names every note of the voicing - with the chord root highlighted - plus recommended fingerings.
