Audio Interchange File Format (AIFF) is a standard for storing uncompressed, lossless sound data developed by Apple Inc. based on the Electronic Arts Interchange File Format. It is predominantly used in professional audio engineering, recording studios, and digital audio workstations for high-fidelity sound manipulation. Although largely superseded by compressed formats like MP3 and AAC in consumer markets, AIFF remains a stable, legacy standard that is generally considered safe from malicious code execution.
