Recording time
The following tables show approximate recording times for different media capacities according to the combination
of sampling frequency, recording bit depth and number of recording channels.

o
The recording times given in the above tables are approximations. Actual recording times might differ depending
on the recording media used.
o
The above times are total possible recording times for the media. They are not continuous recording times.
o
The number of recording channels is the total number of analog input channels and pulse input channels.
o
You can use the following formula as a guide to calculate approximate recording times for other recording media.
Approximate recording time (seconds) = effective recording capacity/(sampling frequency in Hz × number of channels
× analog-digital conversion bit depth in bytes + 8000)
Effective recording capacity: recording capacity – reserved space (in bytes)
Recording capacity: nominal media capacity in bytes (example: 32GB = 32×1000×1000×1000)
Reserved space: approximately 50 MB for headers and other files besides user data
Analog-digital conversion bit depth: number of bytes for the quantization bit depth (4 for 24-bit or 2 for 16-bit)
8000: voice memo transmission speed at 8 kHz fixed sampling frequency with 8-bit quantization (8000 bytes/sec)
