What is an AIFF File?

AIFF (Audio Interchange File Format) is an audio file format standard developed by Apple Inc. in 1988 based on Electronic Arts' Interchange File Format (IFF). It is commonly used on Apple Macintosh computer systems.

Similar to the WAV format on Windows, standard AIFF files contain uncompressed audio data using Pulse-Code Modulation (PCM). This results in very high audio fidelity (lossless) but also leads to large file sizes. AIFF files can store various metadata. A compressed variant, AIFF-C or AIFC, also exists but is less common than standard uncompressed AIFF. Due to its uncompressed nature, AIFF is suitable for professional audio editing and archiving.

AIFF vs. WAV and Other Formats

Quality: Standard AIFF (PCM) offers lossless, uncompressed audio quality, identical to WAV (PCM) and the original source if mastered digitally.
File Size: Very large, comparable to WAV files and significantly larger than lossless compressed (FLAC) or lossy (MP3, AAC) formats.
Compression: Typically uncompressed.
Metadata: Supports storing metadata chunks within the file.
Compatibility: Primarily associated with macOS and iOS. While Windows systems and cross-platform software (like VLC, Audacity) can usually open AIFF files, WAV tends to be more common in Windows environments.
Use Cases: Professional audio editing, mastering, and archiving, particularly within the Apple ecosystem.

How to Open an AIFF File

AIFF files are natively supported on Apple platforms and by many audio applications:

Apple Music / iTunes / QuickTime Player (Native macOS/iOS support)
VLC Media Player (Cross-platform)
Windows Media Player (May require codecs on older versions, better support on newer ones)
Audacity (Audio Editor, Cross-platform)
Most Digital Audio Workstations (DAWs) like Logic Pro, Pro Tools, Ableton Live.

While originating on Apple systems, most modern audio software across platforms can handle AIFF files.
