You need to have Visual Studio installed
# From a Developer Powershell
python scripts/prepare_windows_build.py
# From a normal prompt
pip install .Usage
import loristrck as lt
samples, sr = lt.sndreadmono("/path/to/sndfile.wav")
partials = lt.analyze(samples, sr, resolution=60)
# partials is a python list of numpy arrays
# select a subset of most significant partials
selected, noise = lt.select(partials, mindur=0.02, maxfreq=12000, minamp=-60, minbp=2)
# print each partial as data
for partial in selected:
print(partial)
# plot selected partials
lt.plot_partials(selected)
# now resynthesize both parts separately
lt.partials_render(selected, outfile="selected.wav")
lt.partials_render(noise, outfile="noise.wav")Each partial will be a numpy array of shape = (numbreakpoints, 5) with the columns:
time, frequency, amplitude, phase, bandwidth
