Listening to waveforms

In Matlab I want to hear the differences between what two waveforms sound like. What is the function used to listen to audio in Matlab? For example I have two waveforms from a file

wav1 = wavread('audio1.wav');
wav2 = wavread('audio2.wav');

how am I able to play these waveforms over my speakers?

You should try sound(wav1, 22050). Of course, if you need higher sample rate, you can always change it. You could use just sound(wav1) - however, you should always specify sample rate in order to make sure you hear the waveform properly.

The Matlab command to play a waveform is the sound command. it is used like so:

sound(wav1,F1);
sound(wav2,F2);

where F1 and F2 are the frequency used in playback. you can obtain the frequency from an audio file using your same wavread command thusly:

[wav1,F1,Nbits1] = wavread('audio1.wav');

where Nbits1 is the number of data points in the audio file.
