I have analysed one audio file, which is 1hour of recording, made a spectrogram and everything I wanted to do. I have 60 more files which are the following 60hours of recording which need analysing in the same graphs.

Is it possible to continuously loop through all of the files?

Here is the code:

[slab,S_R,bits] = wavread('E:\1.wav',[1 2]);
