Command line tool for converting Audio to MIDI.

Project description

Midify is a command line tool for converting audio data in MIDI data identifying notes positions and frequencies.

Installation

Inside a virtualenv run

pip install midify

Usage

The simplest usage from the cli:

midify input.wav --output output.mid

You can also use it programatically from python or a jupyter notebook:

import scipy
from midify import midify

rate,data = scipy.io.wavfile.read("input.wav")
mf = midify(data=data,rate=rate)

waveform = mf.fluidsynth(fs=44100)
IPython.display.Audio(waveform, rate=44100)

Algorithm

The algorithm consists of two steps; first we use scipy.signal.find_peaks to find the beggining of each note; after that the program uses scipy FFT to find the first peak in the frequency spectrum which we assume is the root harmonic (the played note).
