I was wondering what exactly is the data stored in two columuns by y. If, for instance, I run y = wavread(a, 44100) (my file has a fs = 44100, so this would mean I am getting all the samples for the first second. Is this right?). So I would imagine y gives me the info, but I don't know exactly what are represented by the two columns). Thanks!

The columns represent channels. Usually column 1 is the left channel and column 2 is the right channel.

The values of y are the amplitude, and for stereo files you get 2 columns.
