pip -r install requirenments.txt

How to run the programm

to run the programm just type python run.py into your commandline

This is what it does so far

A sound file is read, here an a note played by a piano

its fourrier transform extracts frequencies and marks the most important peaks, here one can see the 440Hz of an a and its overtone an octave higher

This will output [ [0, 12] ] which means that the first played note is 0 halftone steps away from the pure a and the second played note is 12 halftone steps away from the "a" which is an entire octave. This means that the second played note is an a' and indeed it is, since a' is the overtone of the a.

You can also give it an entire file and it will tell you the names of the notes played. This currently only works reliantly with single note melody (no triads) and works a little unreliably when multiple notes are played at the same time and it should detect how many are played and extract all notes which are played at the same time. For example when I play 6 it dosn't give back all the right notes but only 4 and maybe even wrong ones if the instrument isn't tuned correctly.
