This format was developed by Apple in 1988 and is based on the Interchange file format (.IFF). Unlike the common MP3 audio format, AIFF and AIF files are uncompressed. This means that while they retain a higher quality sound than MP3, they do take up significantly more disk space—generally 10 MB for every minute of audio. Windows software typically appends the .AIF file extension to these files, while macOS users are more likely to see .AIFF files. One common variant of the AIFF format that does utilize compression, and therefore uses less disk space, is called AIFF-C or AIFC, which stands for Compressed Audio Interchange File Format. Files in these formats typically use the .AIFC extension. How to Open AIFF & AIF Files You can play AIFF & AIF files with Windows Media Player, Apple iTunes, Apple QuickTime, VLC, Media Player Classic, and probably most other multi-format media players. Mac computers can open AIFF and AIF files with those Apple programs, too, as well as with Roxio Toast. Apple devices like the iPhone and iPad should be able to play AIFF/AIF files natively without an app. A file converter (more on these below) may be needed if you can't play one of these files on an Android or other non-Apple mobile devices. How to Convert AIF & AIFF Files If you already have iTunes on your computer, you can use it to convert an AIFF and AIF files to other formats like MP3. Just right-click the file while it's open in iTunes, and go to File > Convert > Create MP3 Version. You can also convert AIFF/AIF to WAV, FLAC, AAC, AC3, M4A, M4R, WMA, RA, and other formats using a free file converter. DVDVideoSoft's Free Studio is a great free audio converter, but if your AIFF file is relatively small, you can probably get away with an online converter like FileZigZag or Zamzar. How to Open & Convert AIFC Files Files that utilize the compressed version of Audio Interchange File Format probably have the .AIFC file extension. They have CD-like audio quality and are similar to WAV files, except that they use compression (like ULAW, ALAW, or G722) to lower the overall size of the file. Like AIFF and AIF files, AIFC files can open with Apple's iTunes and QuickTime software, as well as with Windows Media Player, VLC, Adobe Audition, vgmstream, and likely some other media players. If you need to convert an AIFC file to a different audio format like MP3, WAV, AIFF, WMA, M4A, etc., there are several audio converters to choose from. Many of those converters require that you download the program to your computer in order to save the AIFC file to a new format. However, just like with the uncompressed Audio Interchange File Format we talk about above, AIFC files can also be converted online with FileZigZag and Zamzar. Still Can't Open the File? If these programs aren't opening your file, there's a really good chance that you don't really have a file with any of these file extensions. Read the extension again and make sure you aren't confusing another similarly named suffix to one on this page. Some file extensions look very much alike but that doesn't say much for the file formats; they could actually be completely unrelated and therefore incompatible with the programs listed above. For example, AIT, AIR, and AFI could easily be misread as AIFF or AIF file. However, you can't open files with those three extensions in the same way that you can the other two. The same can be said for many other file extensions, too, like IAF (Outlook Internet Account file), FIC (WinDev Hyper File Database), and AFF (Spellcheck Dictionary Description file). If your file won't work as described on this page, double-check the file extension and then research the true suffix to learn more about the format and see which programs are able to open or convert the file. AIFC also stands for the Australian Institute of Family Counseling. If that's what you're looking for, and not the audio file format, you can visit the aifc.com.au website for more information.
