What is a AIF file?
Uncompressed Apple audio format with CD-quality sound
The .AIF file format was developed by Apple in 1988 and is based on the IFF (Interchange file format). Unlike MP3 files, .AIF files are not compressed. Thus, they are larger than MP3 files and have considerably higher quality audio stored. They are usually 10MB for ever minute of audio. Usually, Windows software will create .AIF files.
Common uses for AIF files
- Professional audio production
- Music mastering
- Archival recordings
- Logic Pro exports
- Professional recording software
- Audio archives
Who works with AIF files?
Voice-over artists, film and TV sound editors, and podcast producers on Mac-based workflows often deliver finished audio as AIF files. Session musicians and mixing engineers also rely on the format when exchanging stems and final masters between digital audio workstations.
AIF vs WAV: which should you use?
AIF and WAV both store uncompressed PCM audio, so sound quality and file size are essentially identical at the same bit depth and sample rate. The practical difference is origin and ecosystem: AIF is Apple's IFF-based format favored by Mac software like Logic Pro, while WAV is the Microsoft/IBM RIFF format more widely expected by Windows applications. Choose AIF for Mac-centric production chains and WAV when a recipient or tool expects the Windows standard.
