How to apply DTW to 2 WAV audios

Hi, I would like some help to apply DTW to two audios in .WAV format. I'm trying in the following way, but without success:

      [wave1,Fs1] = audioread('audio1.wav');
      [wave2, Fs2] = audioread('audio2.wav');

      dtw(wave1,wave2);

and

audio1 = audioread('audio1.wav');
audio2 = audioread('audio2.wav');

Still unsuccessful

You may have better luck using a spectrogram to match audio signals.

Have a look at the example here: Finding Time-Stretched Power Signals

Hi, thanks for the answer, this solution answered me, though, it just shows me the plot chart, is there any way I use it as a true or false? For example, if there are any signs found, it will execute a command, if it does not find it, it will execute another one. With the output in plot I can not create a variable to receive the amount of signals found.

Is there any way to add the value of the amount of signals found in a variable?

Sorry for bad inglês.

I think you can try taking the distance that DTW gives you and do some processing on it (e.g. if the distance is less than some threshold based upon some function of the power of the test signal to match).

Thanks Greg.
