• [1] accuracy is mean raw pitch accuracy on 1000 samples of MIR-1K dataset

install

all agorithms tested on python3.10, this is recommended python version to use

pip install pitch-detectors

usage

from scipy.io import wavfile
from pitch_detectors import algorithms
import matplotlib.pyplot as plt

fs, a = wavfile.read('data/b1a5da49d564a7341e7e1327aa3f229a.wav')
pitch = algorithms.Crepe(a, fs)
plt.plot(pitch.t, pitch.f0)
plt.show()

additional features

• robust (vote-based + median) averaging of pitch
• json import/export
