Shell script reads from text file which needs to be formatted like this:

Convert all

Will fill in soon

mp3 to wav

mp3 to wav coversion is done with the ffmpeg package that can be installed on the command line with the following command: sudo apt-get install ffmpeg

wav to midi

wav to midi is done using the program waon found here.

midi to csv

midi to csv is done by the included midicsv.exe found here. This file is included in the source here so it does not need to be downloaded again.

How it works

This program first collects an mp3 from youtube-dl for ease of collecting mp3s:

• mp3 --> wav
• wav --> midi
• midi --> csv

There is a batch script that performs all of these tasks and places each file that it creates in it's respective folder.
