This project implements the click-removal algorithm proposed in
Oudre, Laurent. 2015. “Automatic Detection and Removal of Impulsive Noise in Audio Signals.” Image Processing On Line 5 (November): 267–81. https://doi.org/10.5201/ipol.2015.64.
Oudre, Laurent. 2018. “Interpolation of Missing Samples in Sound Signals Based on Autoregressive Modeling.” Image Processing On Line 8 (October): 329–44. https://doi.org/10.5201/ipol.2018.23.
The project uses MATLAB.
wholeWorkflow.m implements the entire detection and interpolation process in one script. It reads an audio file and write the declicked signal into another one.
To make experiments easier, it is functionized in deClick.m and called in the master experiment script main.m.
The other scripts in the repository are for various experiments and visualizing the results.
Some audio extracts corrupted by impulsive noise can be found here: http://www-sigproc.eng.cam.ac.uk/Main/SJGSpringer
Feel free to download some of those audio files and play with the parameters in the code.
