What are AIFC files and how to open them

Are you having problems opening an AIFC file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your AIFC files.

What is an AIFC file?

An .AIFC file is an AIFF-C (Audio Interchange File Format Compressed) file.

AIFF-C ("Audio Interchange File Format Compressed", extension .aifc) is a digital audio file type used when standard AIFF files need to store audio in a compressed form or with alternative encodings. It enables saving sampled sound (mono, stereo, or more channels) at various sample rates and bit depths while using compression to reduce file size or special coding (such as floating-point or logarithmic encodings) beyond plain linear PCM.

Apple introduced AIFF-C in August 1991 as an extension to AIFF. It is produced by audio software that supports its compression scheme; after creation, it is usually used for storage, transmission, or playback by players and audio tools that know how to read the compressed or special-encoded data. AIFF-C can also store uncompressed PCM audio under the compression type "NONE" and supports newer types including "sowt" (byte-swapped PCM), floating-point formats like 32-bit or 64-bit, A-law and μ-law encodings.

Files start with a "FORM" identifier in the IFF container format, and AIFF-C files include a "FVER" chunk (versioning) which does not appear in basic AIFF.
