Effect of high frequencies in audio signals and intricacies in audio research

A nice article describes why high sampling rates are not required for audio. The audio signal is the most intriguing of all signals. It is quasi-periodic but non-stationary over long  periods above 20 ms.

I have been evaluating instants of maximum excitations or epochs and I was using 3 Core i5 systems simultaneously as I had to the run the same code using different parameters to get the best performance and accuracy. I have re-refined my output recursively so as to get the best accuracy and identification rates.
