Recording Duration

The table below shows the maximum recording time on SD/SDHC cards of different capacities for different file formats for recording.

File format(recording setting) SD/SDHC card capacity(hours:mintes)
1GB 2GB 4GB 8GB
WAV/BWF 16bit(STEREO) 44.1kHz 1:41 3:22 6:44 13:28
48kHz 1:33 3:06 6:12 12:24
96kHz 0:46 1:33 3:06 6:12
WAV/BWF 24bit(STEREO) 44.1kHz 1:07 2:15 4:30 9:00
48kHz 1:02 2:04 4:08 8:16
96kHz 0:31 1:02 2:04 4:08
  • The recording times shown above are estimates. They might differ depending on the SD/SDHC card in use.
  • The recording times shown above are not continuous recording times, but rather they are the total possible recording times for the SD/SDHC card.
  • If recorded in mono in WAV files, the maximum recording time will be double the figures above.
  • For dual and 4-channel recording in WAV/BWF format, the recording times are about half those shown above.
