Abstract
A system for processing a digital audio signal that includes a plurality of samples is disclosed. The system comprises a magnitude determination module, a windowing module, a summing module and a comparison module. The magnitude determination module determines a magnitude of each of the plurality of samples of the digital audio signal. The windowing module selects a subset of the plurality of samples, which are summed by the summing module to obtain a subset sum. The comparison module compares the subset sum to a threshold, and generates a silence indicating signal based on the comparison of the subset sum to the threshold. The silence indicating signal is indicative of a period of silence in the digital audio signal.
