Usage

Install

pip install py2shpss

Code Example

# import
import numpy as np
import scipy.io.wavfile as wavfile
import py2shpss

# load music
sr, sig = wavfile.read("your_awesome_music.wav")
if len(sig.shape) == 2:
        # mix left and right channels if stereo
        sig = np.mean(sig, axis=1)
sig = sig / np.max(sig)

# process and save
twostageHPSS = py2shpss.twostageHPSS(samprate = sr)
harmonic, vocal, percussive = twostageHPSS(sig)
wavfile.write("vocal.wav", sr, vocal)
