What is a AIF file?

An AIF file is an audio file saved in the Audio Interchange File Format (AIFF). It contains uncompressed high-quality audio similar to a .WAV file and is commonly used to store standard CD audio.

Apple Computer developed the AIFF format in 1998, basing it on Electronic Arts' .IFF format. Standard AIF files use a sampling rate of 44.1KHz, are 16-bit, and have two channels for stereo sound.

AIF files are similar to .MP3 files, but they are saved in an uncompressed format, whereas MP3 files are compressed. This difference results in larger AIF files while storing higher-quality audio.

NOTE: AIF files may also be saved with the .aiff file extension (.AIFF files).

How to open a AIF file

You can open AIF files with various media players, such as Microsoft Windows Media Player (Windows), Apple QuickTime Player (Mac), Apple Music (Mac), and VideoLAN VLC media player (multiplatform).

How to convert a AIF file

Various applications, including the Adobe Audition and Audacity digital audio workstations (DAW), can convert AIF files to other file types.
