[SIGNAL, SAMPLERATE]=audioread(file);

SIGNAL = SIGNAL(:,1);

dt = 1/SIGNAL;

t = 0:dt:(length(SIGNAL)*dt)-dt;

plot(t,SIGNAL);

xlabel('Seconds');

ylabel('Amplitude');

figure

plot(psd(spectrum.periodogram,SIGNAL,'Fs',SAMPLERATE,'NFFT',length(SIGNAL)));

sound(SIGNAL, SAMPLERATE);

error message:

Error using plot

Vectors must be the same length.

Error in Recognizer (line 17)

plot(t,SIGNAL);

I want to plot my audio signal, but I get this error. anybody can help me?

thanks

There seems to be some confusion in your code, purely based on line 2 and line 3 of your code. Is SIGNAL a scalar or vector?

Line 2 seems to imply that SIGNAL is a vector, while Line 3 seems to imply SIGNAL is a scalar. Please check your code
