There is a maximum recording size according to file type, as follows:
• AIFF: The AIFF file format cannot handle audio file recordings larger than 2 GB:
• For 16-bit, 44.1 kHz stereo files, this equals a recording time of about 3 hours and
15 minutes.
• WAVE (BWF): The WAVE file format cannot handle audio file recordings larger than
4 GB:
• For 16-bit, 44.1 kHz stereo files, this equals a recording time of about 6 hours and
30 minutes.
• CAF: If the size of your recording exceeds the above limits, choose the CAF (Apple
Core Audio Format) file format, which can handle the following recording times:
• About 13 hours and 30 minutes at 44.1 kHz
• About 6 hours at 96 kHz
• About 3 hours at 192 kHz
The bit depth and channel format—mono, or stereo—do not affect the maximum
recording size of CAF files.
