Filters the waveform by means of median smoothing.

Documentation

Filters the waveform by means of median smoothing.

This is a sort of low pass filter which aims to remove extreme values. Median smoothing works examining each sample in the wave, taking all the values in a window of size n around that sample, sorting them and replacing that sample with the middle ranking sample in the sorted samples.

Parameters:

sig - waveform to be filtered
- n size of smoothing window
