hi, i would like to compare audio files using the dtw() function.
i read my audio files using the [y,Fs] = audioread() function.
but the problem is :
when i send my audio data vector, (y) to the dtw function : dist = dtw(y,y) for example,
i get error that my vector y is too big, when i try cutting the vector into part i dont get the result im waiting for, so, my question is :
how can i make my vector (y) shorter and get a good result from the dtw functuion?

Provide more information about your signal or better to upload it. To make a signal "shorter" is by resampling at a lower sampling rate, but keeping Nyquist law satisfied.

maybe it already helps to take just one of the stereo channels if your audio was recorded in stereo
