Sound manipulation and representation via partial-tracking
Project description
SNDTRCK
Partial tracking in python 3
Dependencies
Mandatory
- python >= 3.7
- numpy
- bpf4: interpolation curves
- sndfileio: simple API for reading and writing sound-files
- loristrck: partial tracking analysis based on Loris. See the project for its own set of dependencies
Optional but HIGHLY recommended
- pyqtgraph: efficient plotting via Qt
- h5py: allows saving partial-tracking data as HDF5. You need to install hdf5.
Installation
We assume that pip
points to your current python >= 3.7 installation. Otherwise use pip3
and python3

$ python setup.py install
Basic Usage
Example 1
import sndtrck
spectrum = sndtrck.analyze("/path/to/sndfile", resolution=50)
# Get the chord at 500ms, but only the partials louder than -30 dB
print(spectrum.chord_at(0.5, minamp=-30))
# [A3+, C5+10, E5-13]
spectrum.plot()
spectrum.show() # this will show you the spectrum in the default applicatio for your system
spectrum.write("spectrum.sdif")
Features
- analysis of sound-files in many formats
- automatic configuration of analysis parameters
- filtering of partials based on multiple criteria
- resynthesis
- plotting
- export the spectrum to many different formats (sdif, hdf5, midi)
