I want a MATLAB code for removing silence from a speech signal..

I need a short and simple code..

Answer 1

[Walter Roberson]

Suppose that your signal is stored in S. Then

newS = S( any(S,2), :);

This will create newS that has only the places where at least one of the sound channels is non-zero. For this purpose, I have defined "silence" as a sample value exactly equal to 0, of any duration.

Short and simple (and simplistic)
