Cant make out what is being said.I feel that either the word society or suicide is being used.


MATLAB CODE

%Naman Anand Verma

% Program to open a wav file ,reverse it and write it as a new file .Then

% reduce the bitrate of the reverse file and write it again.

clc;

clear;

% wavread command converts the .wav file to the digital signal data x[n]

[jpforward,srate,btrate] = wavread('H:\pu.data\Desktop\jpforward.wav'); 


%wavplay command makes us listen to the digital signal x[n]

wavplay(jpforward,srate);

%commands to reverse the file

reverse_jp=flipud(jpforward);

wavplay(reverse_jp,srate);

%command to write the file

wavwrite(reverse_jp,srate,btrate,'H:\pu.data\Desktop\jpreverse.wav');

%command to decrease the bit rate so the words sound slow.

x=srate/2;

wavplay(reverse_jp,x);

wavwrite(reverse_jp,x,btrate,'H:\pu.data\Desktop\slowjpreverse.wav');
