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.
