AIFF, or the Audio Interchange File Format, is a digital audio file format used for storing high-quality sound. Developed by Apple, it is commonly used in professional audio applications because it supports uncompressed audio, which means the sound quality remains intact. AIFF files can store various types of audio data, making them versatile for musicians and sound engineers. One of the key features of AIFF is its ability to include metadata, such as song titles, artist names, and album information. This makes it easier for users to organize and identify their audio files. While AIFF files can be larger than other formats like MP3, their superior sound quality makes them a preferred choice for many audio professionals.
