A simple yet very powerful noise remover and reducer built in python. The noise removed by using Wavelet Transform.
Wavelets has been very powerful tool to decompose the audio signal into parts and apply thresholds to eliminate unwanted signal like noise. The thresholding method is the most important in the process of Audio De nosing.
The thresholding used is VisuShrink method or the universal threshold introduce by Donoho
This repo uses pywt
. I have a custom implementation of wavelet here wavelets & wavelets-ext (cython speed up)
$ pip3 install -r requirements.txt
Use the denoise.py file
from denoise import AudioDeNoise
audioDenoiser = AudioDeNoise(inputFile="input.wav")
audioDenoiser.deNoise(outputFile="input_denoised.wav")
audioDenoiser.generateNoiseProfile(noiseFile="input_noise_profile.wav")
