Exporting AIFF from FCP 7
FCP 7.0.1 is giving me AIFC files instead of AIFF upon export. Need them to be the uncompressed AIFF version. Any help as to why it’s compressing to AIFC instead? I’ve looked all over, can’t seem to find the solution. Thanks.

You can read all about it here –
https://en.wikipedia.org/wiki/Audio_Interchange_File_FormatBut here’s the important bits –
“With the development of the Mac OS X operating system, Apple created a new type of AIFF which is, in effect, an alternative little-endian byte order format.”
“Because the AIFF architecture has no provision for alternative byte order, Apple used the existing AIFF-C compression architecture, and created a “pseudo-compressed” codec called sowt (twos spelled backwards). The only difference between a standard AIFF file and an AIFF-C/sowt file is the byte order; there is no compression involved at all.”
In a nutshell, the file is uncompressed aif, nothing to worry about.
Note: As of Mac OS X version 10.4.9, the system will sometimes incorrectly display the AIFC icon for files with the .aif extension, whether or not the actual file format is AIFF or AIFF-C. This can be verified by opening the files in a hex editor and checking the FORM chunk’s form type. This can sometimes happen when exporting files from QuickTime, and frequently happens when sending and receiving files between Windows and Mac computers or extracting files from an archive.
