Midify
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 midifyUsage
The simplest usage from the cli:
midify input.wav --output output.midYou 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).
