audio encoding (see also PCM). This algorithm encodes the difference between an 
actual audio sample amplitude and a predicted amplitude and adapts the resolution 
based on recent differential values.

ACR Decrease Time Factor: This is the time permitted between sending RM-cells 
before the rate is decreased to ICR (Initial Cell Rate). The ADTF range is 0.01 to 
10.23 sec. with granularity of 10 ms.
