This code is a simple implementation of , . The function trmszc implements the main algorithm. The input of the method is a .wav file.
Instructions about the parameters of trmszc and how to run it, are given as comments in the start of trmszc.m.
It yields a sound segmentation and classification with 20 msec accuracy.
Classes: Music, Voice(Speech), Silence

Thanks for the suggestion, the code has been updated now including only the second for
I was going through your source code and confused with the following scope:
we can see that P indeed updated by (1-omiot2(i-1)), but why make it updated with (1-omiot2(i-1))*(1-omiot1(i-1)+1-omiot1(i))*(1-omiot2(i-1)) just above it which is not necessary and expends the computation ?
Hello，my dear friend.Now i can run it and get two
picture as result,but i can not understand many detail.Can you help me?My QQ is 2268326043,if you have time,contracting me! When you contract me ,remarking "matlab",thank you!!
zc = 0;
if y(i)*y(i-1) <= 0,
zc = zc+1;
I have a question.Can not these code run?
I have tried many times,but i can not get right result.Can you help me ?
It computes the number of number of times that the sign of the given signal y changes (from positive to negative or from negative to positive).

what does the following code mean.?
%Computes the number of Zero_Crossings of signal y
function [zc] = Zero_Crossings(y)
zc = 0;
if y(i)*y(i-1) < 0,
zc = zc+1;
