Play last third of a wav file

this is part of a question I have to create a program for, I have no code just yet, but I was wondering how to play the last part of a wav file as asked: The second WAV file will have the last Hallelujah repeated three times (and no other sound). any help for this part will get me going in the right direction thanks.

hi, try :

 sound(y(2/3:end,Fs); % with Fs the sampling frequency

% EDITED ANSWER

ok Walter is right the answer is not complete/wrong, here is the correct version :

 % example :
 data=load('gong.mat')
 y=data.y;
 Fs=data.Fs;
 N=length(y);
 sound(y(round(2/3*N):N),Fs); % round|ceil|floor

[Walter Roberson]

sound( y( round(2/3*end):end ), Fs)

You pretty much do have code for this. It's in your other question: my code in my answer. The code just needs slight adaptation.
