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.
