Congrats Mark !!! the pic is cute Cool guys ...its heartening to see so much replies...... The DSP language used above is hard to fathom ..... "I see what you mean, autocorrelate a big time vector containing repeats" I dont clearly derive a solution out of this reply ...... can anybody explain on what he means......

Yo. The problem has been solved by Tristan Jehan. I would look into his research at the Media Lab. Perhaps you could adapt his techniques to use less memory. Generally speaking, he examines chunks of sound, putting dividers in where attack transients are likely.
