Answer:

The correct answer is Adaptive differential pulse code modulation

Explanation:

Adaptive differential pulse code modulation (ADPCM) is a variant of differential pulse-code modulation (DPCM) that varies the size of the quantization step, to allow further reduction of the required data bandwidth for a given signal-to-noise ratio. The output data rate can be dynamically adjusted between 16 kbit/s and 64 kbit/s in these applications.
