Classification: CPC G  H | IPC G

Claim 3:
4. The system of claim 3, wherein the processing circuitry of the audio compression device is further configured to:
identify a second time window of the plurality of time windows, the second time window being immediately subsequent to the first time window;
determine a second number of delta bits different from the first number of delta bits and a second sample count for the second time window, the second time window comprising a second group of time-domain consecutive samples of the plurality of quantized PCM samples according to the second sample count;
for each sample of the second group of time-domain consecutive samples, encode the sample into a corresponding set of delta bits using the second number of delta bits based on a difference from a previous sample to the sample being encoded to generate a second stream of delta bits; and
encode the second sample count and the second number of delta bits in a corresponding second header for the second time window.
