Urgent - Audition reads wrong length when importing multitrack AIFF

Question

Hi all,I'm an infrequent user of Audition, but I have a 28GB multitrack Mac AIFF file that I'm trying to import. If I start a new multitrack project and drag it into the Audition timeline, it imports all tracks (28 of 'em) in the correct order, but it only imports 10:44 of the file. It should be a little over 2 hours. The MediaInfo app tells me the file is "Duration: 2 h 15 min" which sounds right.What can I do to import this file into Audition correctly? Thanks for any advice! Audition 25.0.0.47 running in macOS Sonoma 14.7.2 on MacBook Pro with Apple M3 Max

Thanks @rosita_9807 for your prompt reply. It turns out that the problem was actually that AIFF files as well as WAV files have a length field in their headers which is only 32 bits, which limits their filesizes to a max of around 4GB. Apparently the software I was using blithely kept writing audio data without worrying about the header length field. So with 24 tracks of 24-bit 48KHz audio, it ran out of space pretty quickly.

The correct solution (for me, anyway) was to use a format that supports a 64-bit length field, like RF64 (essentially a WAV file with 64-bit length field) or a CAF file (Apple's extended-length version of AIFF). I used CAF, and things worked great. Audition imports CAF files, and so I now can happly record 2-1/2 hours of 48K 24bit audio from my mixer.

Hello!If Audition imports only part of your 28GB AIFF file, check the file integrity, try splitting it into smaller segments, or convert it to a compatible format like WAV. Ensure Audition is updated, and check Preferences > Media & Disk Cache for sufficient space.
