- Description
- The IFF (Interchange File Format) is a file format originally developed by Electronic Arts and Commodore-Amiga in the 1980s. It was designed to facilitate the sharing and storage of multimedia data, such as images, audio, and video, between different software applications and systems. The format is chunk-based, allowing it to encapsulate various types of data within a single file by organizing them into self-contained blocks. While it was most prominently used on Amiga computers, the IFF format has influenced the development of subsequent file formats, including the widely used AIFF (Audio Interchange File Format) for audio files.
- M4R is an iTunes ringtone file that stores mono channel audio. They are identical to the M4A format files only that they are correctly used for ringtones.
