我应该找到可以用于歌曲的最小带宽仍然可以被听众区分
这是我目前的代码
% A.Read the song and assign vules
[y, fs] = wavread('Dog Woof.wav');
time = (1:length(y))/30000;
plot(time, y); % ploting the sin wave of the song
title('Sound waves');
xlabel('Time');
ylabel('Frequency');
% B.Simple rate will be the fs value
fs
% C.Bandwidth
[UPPER, LOWER] = bandwidth(y)
