Abstract:
1. A method of selecting a region of high quality audio content comprising: selecting a digitized Audio Content (AC) to analyze from a stored database, where a user selects the AC by at least one of a graphic user interface (GUI) and a tactile interface; generating at least one digitized quality characteristic function (QCF) each having a related quality threshold value (QTV); generating a related binary quality characteristic function (BQCF) for each of the at least one QCF using the related QTV, where the BQCF is expressed digitally in Os and 1s and saved in computer readable medium; applying a related digitized weight value to each related BQCF to generate a related weighted QCF (WQCF), where the values of the WQCF vary from 0.0 to 1.0; and summing all of the WQCF generating a single quality characteristic function (SQCF); selecting a weighted audition window (WAW); moving the WAW along the SQCF in increments of time, wherein the region of the SQCF inside the WAW is summed to generate a weighted summed value associated with the WAW position along the SQCF, where the position is the location of the start of the WAW, wherein a multiple of weighted summed values and their associated positions define a weighted start function (WSF); and selecting the position of the maximum weighted summed value as the start position.
