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
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: 1 TB = 1000×1000×1000×1000)
Reserved space: headers and other files besides user data that use approximately 50 MB
Analog-digital conversion bit depth: bytes required 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)
Calculation example
Total recording time for 16 channels at 192 kHz sampling frequency with 16-bit quantization on a 1TB RDX HDD:
Recording time (seconds) = (1000 × 1000 × 1000 × 1000) - (50 × 1024 × 1024)/(192 × 1000 × 16 × 2+8000)
= 162540 seconds = 1 day, 21:09:00
