Abstract:
1. A non-transitory computer-readable medium containing instructions that, when executed by a processor, cause a set of steps to be carried out for identifying a mute/sound attribute of a current sample set of audio, said current sample set having a plurality of first-channel samples and a plurality of second-channel samples, said set of steps comprising: receiving said current sample set; for each said first-channel sample, determining a first max amplitude and a first min amplitude; calculating a first span based on a first function of said first max amplitude and said first min amplitude; for each said second-channel sample, determining a second max amplitude and a second min amplitude; calculating a second span based on a function of said second max amplitude and said second min amplitude; and identifying said current sample set as having a sound attribute responsive to two conditions being satisfied, the first of said conditions being that said first span is greater than a min-volume threshold, the second of said conditions being that said second span is greater than said min-volume threshold; and storing in a memory an indication of an associated mute/sound sample-set attribute.
