where k is the coefficient, showing how many times the maxi-
mum record time decreases at record mode change relative
to 2-bit ADPCM mode. For example, the record time will be
1120/5=224 minutes for model 1120 in the without-compres-
sion mode, at sample rate of 8 kHz (k=5).
Memory consumption in the Stereo mode increases twice as
much compared with the Mono mode.
