ABSTRACT:
Quantizing optimizes compression encoding for transmission of audio data. A working set of most frequent sound levels in a sequence of audio samples is determined from a histogram. Sound levels from the working set are then substituted for original sound levels in the subject audio data. This filters the audio data by increasing redundancy and decreasing granularity/resolution.
