Abstract
A system comprising an audio compression device is provided. The audio compression device receives a plurality of pulse code modulated (PCM) samples, performs a quantization of the plurality of the PCM samples, and determines a plurality of time windows for the plurality of quantized PCM samples. The audio compression device further determines a first number of delta bits and a first sample count for a first time window of a plurality of time windows, where the first time window includes a first group of time-domain consecutive samples according to the first sample count. The audio compression device encodes the sample into the first number of delta bits based on a difference from a previous sample to generate a first stream of delta bits, and encodes the first sample count and the first number of delta bits in a corresponding first header for the first time window.
