What is an AIFF File?

AIFF, short for Audio Interchange File Format, is an uncompressed audio file format developed by Apple. It is popular among Mac users and is known for its high audio quality and fidelity.

Key Advantages of AIFF Files:

Lossless Quality: AIFF files retain the full quality of the original audio source, making them suitable for professional audio applications.

Wide Compatibility: Supported by most audio editing and playback software on both Mac and Windows platforms.

Metadata Support: AIFF files can include metadata, though not as extensively as some other formats like FLAC.

Limitations of AIFF Files:

Large File Size: Uncompressed AIFF files can be large, which may impact storage and distribution.

Less Efficient Compression: AIFF does not compress audio data, resulting in larger file sizes compared to compressed formats.


AIFF is preferred by users who prioritize audio quality and compatibility across different platforms, particularly within the Apple ecosystem.
