This is a pitch detector that can be used to tune any instrument in equal temperament. It receives any sound from the mic input, detects its pitch, and displays its distance from the nearest note.

For pitch detection it implements the YIN algorithm, considered the best publicly available method. YIN cannot run entirely on matlab code, demanding routines are implemented in C.


Use microphone or plug your instrument directly into mic-in for better capture.
Mic sensitivity can be adjusted from your system's recording controls (not play controls).

Choose a compiler that works:
>> mex -setup

Compile the MEX file:
>> mex dfopt.c

Run it:
>> tuner

Work with cents instead of hertz:
set accuracy=0 in yint.m


The application is kept as simple as possible. There may follow a version with more UI options.
I am currently working on the web version built entirely on open web technology (html/css and js).

Leave feedback!!! or comment. Thanks.
