Vectors must be the same length.

Every time I run this code, I get "Error using plot Vectors must be the same length.

Showing error in line-8.

reading the audio input signal

[y, Fs] = audioread('recording for lab.wav')

x = resample(y, 8000, 44100);

info = audioinfo('recording for lab.wav')

t = 0:seconds(1/Fs):seconds(info.Duration);

t = t(1:end);

figure()

subplot(1,1,1)

plot(t,y)

xlabel('time')

ylabel('amplitude')

title('audio signal')

It sounds like you haven't checked whether the error message is true..

[Nitin Phadkule]

size of t and y must be same i.e. number of values in array t and y must be equal

[Mathieu NOE]

hello ,

You are not using Fs info to generate the time stamps (uh !) , and even worse you do a resampling function and do not apply the implication on Fs (that then would generate the right t vector)

so no wonder signal and time vector are of different length

A small err in t's size:

...
t = t(1:end-1);        % 1 last value has to be removed.
