Using Matlab

If given a wav file such as speech.wav

Write a code that would resample the speech.wav file using the resample function such as one variable like x or y = resample( another variable, 5, 3);

and then be able to plot the original wav file speech.wav and then plot the resampled wav file to comprare to each other

also write the code that would then play the sound of the new resampled wav file but won't play the original wav file

Note: do not use wavread to read the wavfile and instead use audioread like [y,Fs] = audioread('speech.wav');

Explanation / Answer

%Use the audioread function to read the file, speech.wav.

[y, Fs] = audioread(‘speech.wav’);

% where y is the raw signal and Fs is the sampling rate.

% The resample function is used to change the sampling rate of the raw signal to other rate which is

% decided by a ratio of two integers.

y_sample = resample(y,5,3);

plot(y)

hold on

plot(y_resample)

sound(y_resample) % this function plays the resampled sound
