Digital representation of audio waveforms using peak shifting to provide increased dynamic range

摘要: A system allows greater dynamic range in fixed-width sample representations of waveforms. Known properties the waveform are used to determine an unlikely, or impossible, data condition be as exception condition. In a preferred embodiment that is directed processing audio waveforms, first large value transitioning second different sign indicate Samples following assumed shifted by predetermined amount so their representation within allowable word results extended range. embodiment, pre-processing create conditions and perform “peak packing” shift portions would otherwise become clipped, peaks reside position digital representation. Analogously, playback serves detect restore back original status for, e.g., audible digital-to-analog playback, high-resolution processing, etc.
