VQL (Variable Quantizing Level)

A voice compression technique that encodes analog voice signals

in blocks, adjusting the size of the quantizing steps based on the highest amplitude value in each block.

VQL supports high-quality voice at a rate of 32 kbps, a 2:1 compression ratio, as compared to pulse code modulation (PCM). See also amplitude, analog, compression, encode, PCM, and quantize.
