NoiseCut

OBS noise reduction from horizontal and vertical components using harmonic-percussive separation algorithms

Example of one day OBS signal

After installing the package, in order to denoise a signal you can use the following code. The outputs are the denoised signal and the spectrogram as below.The spectrogram shows only the frequency range of [0-1] Hz.

import noisecut
import obspy

st = obspy.read('D10.DO.HH4..D.2012.080.000000')
hps_trace, spectrograms = noisecut.noisecut(st[0], ret_spectrograms=True)
noisecut.plot_noisecut_spectrograms(*spectrograms)

Installation

For the installation you need to clone the repository. Then run "python setup.py install" in the terminal. You need the Numpy version of 2.21.
