Search for noise. Take any short sound (probably in .wav or .aif format, possibly others, but mp3 does not work well), and open it in a text editor such as BBEdit. You will see more or less garbage. Leaving aside the first hundred characters or so (which contain header information about the file) edit the file in any way you see fit. Cut and paste sections from one place to another. Rearrange lines. Reverse or sort sections of text. Munge it with a perl script. Paste in an email.
Some edits will have more interesting results than others. Many edits may have no result, or make your file unplayable – be persistent. Continue incrementally until the source material is unrecognizable.
