Detailed Description

Some of these filters are non-linear and therefore don't fit the normal paradigm.

Function Documentation

void simple_mean_smooth	(	EST_Wave &	c,
		int	n
	)

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

c	waveform to be filtered
n	size of smoothing window
