AIFF: a high-quality audio file

This format first emerged in the late 1980s as a development of Apples specialists. It is a standardized format for storing audio data. AIFF files are not compressed, which is why they are larger than mp3. The audio file contains samples and loop information. It is most often used by qualified musicians who need high-quality sound. One minute of audio in the AIFF format requires 10 megabytes of disk space. The encoding process excludes data loss, which makes this format similar to WAV.
