What “reviewed” means on this page
  • Format fit: whether the “what is this file?” description matches common real-world use of the extension, including category, typical MIME types, and aliases.
  • Opening paths: whether Windows / macOS / Linux steps read plausibly for current OS dialogs and default apps; we remove fantasy menus and unsafe shortcuts.
  • Security framing: whether risk notes match the extension class (for example executables vs plain data) and whether affiliate wording does not contradict the security section.
  • Sources and further reading: whether external links point to vendors, standards bodies, or other primary references where possible; we avoid inventing details we cannot ground.
  • Limits: this is clarity and safety-messaging QA, not a guarantee that every statement is exhaustive or that every binary you download is harmless.

What is a .AIFF file?

.AIFF stands for Audio Interchange File Format, developed by Apple. It is used for storing high-quality audio data and is widely used in professional audio environments.

Background

The AIFF file format was developed by Apple in 1988 and is commonly used for storing sound data on computers and other electronic audio devices. It is a non-compressed format that provides high-quality audio, making it ideal for professional audio applications such as music production and sound editing. AIFF files are similar to WAV files but are more commonly used on Apple devices. They can store metadata and loop point information, which is useful for audio engineers and musicians. Despite their high quality, AIFF files tend to be larger in size compared to compressed formats like MP3, which can be a consideration for storage and streaming.
