## What is Tine?

Most tuners are guessing. Most metronomes are drifting. Tine does neither, and this describes exactly why.

THE TUNER READS THE NOTE, NOT THE LOUDEST HARMONIC
The easy way to build a tuner is to take an FFT and pick the loudest frequency. It fails twice on real instruments. A 4096-sample window has bins about 11 Hz apart, which down at the bottom of a guitar is most of a semitone - you cannot read cents off that. And on a low E string the second harmonic is routinely louder than the fundamental, so a peak-picking tuner reports the note an octave too high, confidently.

Tine measures periodicity in the time domain instead. Across 222 test tones spanning B0 to C7 - pure sines, harmonically rich sawtooths, and plucked strings with a deliberately crippled fundamental - the worst error is 0.27 cents. That is roughly nineteen times finer than the 5-cent window in which it calls a note in tune.

THE METRONOME IS SAMPLE-ACCURATE
Every click's position is computed from its index, never by adding an interval to the click before it. That distinction is the whole thing: interval-adding accumulates error for as long as you play, while this stays within half a sample - about 11 microseconds - after an hour, or after four.

THIRTEEN TUNINGS
Guitar, and Drop D, E flat, and open G. Bass in four and five strings. Ukulele, violin, viola, cello, mandolin, banjo. Or chromatic, which just tells you what you played. Tap any string to hear its target pitch and tune by ear.

REFERENCE PITCH FROM 410 TO 460 HZ
Concert pitch is 440. Orchestras often tune to 442 or 443, and baroque ensembles to 415. Tine follows whichever you set, and every reading follows with it.

A METRONOME THAT COUNTS REAL MUSIC
2/4 through 7/4, and 3/8, 5/8, 6/8, 7/8, 9/8 and 12/8. Eighths, triplets and sixteenths. Tap tempo. A mute that keeps counting, for practising your own time. The Italian marking under the number, because the tempo on the page is usually a word.

NOTHING ELSE
No account, no sign-up, no network connection of any kind. Audio is analysed on the device, never recorded, never stored, never sent anywhere. One price.
