Pulse Code Modulation
from the science of digital media by Jennifer Burg page193 :
that signals be sampled and encoded in binary, and the bits be transmitted as pulses representing 0s and 1s.
DPCM (Differential pulse code modulation ) --Because the amplitudes of sounds in human speech do not change dramatically from one moment to the next,
it is possible to reduce the bit depth by recording only the difference between one sample and the succeeding one.
ADPCM -- fine-tuned so that the quantization level varies in accordance with the dynamically changing characteristics of the speech pattern.
