Chromatic Tuner & Strobe

Tune any instrument. Needle or strobe, every feature free.

Chromatic Tuner & Strobe finds the nearest note to whatever you play or sing, from A0 to C8, and shows how far you are in cents. Made for wind and brass players, string players, singers, band and orchestra musicians, teachers and students.

TWO WAYS TO SEE YOUR PITCH
• Needle: a large ±50 cent gauge with an in-tune zone you can set to ±1, ±3 or ±5 cents.
• Strobe: bands drift left when you are flat, right when you are sharp, and stand still when you are in tune. Three bands at different octaves, like a real strobe tuner, with a visual resolution finer than one cent.

PRECISE AND STEADY
• A YIN pitch detector with confidence, noise gate and octave checks: no random notes in a silent room.
• Longer analysis windows for low notes, shorter for high ones, so a tuba and a piccolo both read quickly.
• Clear messages instead of invented readings: play a note, a little louder, one note at a time, too loud.
• Big note name with octave, signed cents and frequency with two decimals.

TRANSPOSING INSTRUMENTS
• B♭, E♭, F, G, A and D, or pick your instrument: clarinets, saxophones, trumpets, horn, flutes, oboe, cor anglais, bassoon, trombone, euphonium, tuba, strings, guitar, bass, ukulele, voice, piano.
• The written note is shown in large type with the right octave (tenor sax, baritone sax, bass clarinet), the concert pitch stays visible in small.
• Each instrument also narrows the listening range for steadier readings.

CALIBRATION AND TEMPERAMENTS
• Reference pitch A4 from 415 to 466 Hz in steps of 0.5 Hz, with presets 415, 430, 432, 440, 442, 443 and 444 Hz.
• Equal temperament or historical ones: Pythagorean, just intonation, quarter-comma meantone, Werckmeister III, Kirnberger III, Vallotti and Young, in any key.

PRACTISE LONG TONES
• A 10-second pitch history under the note shows how steady your tone is.
• See the share of time each long note stayed in tune.
• Lock a target note to measure every sound against it.
• A reference drone on any note, to tune and practise intonation (use headphones).

Note names in C D E, Do Re Mi or German H, with sharps or flats. Dark and light theme, 71 languages.
