Audio Interchange File Format (AIFF) is a lossless audio standard developed by Apple Inc. for storing uncompressed pulse-code modulation data. It is primarily utilized in professional audio production, mastering, and studio recording environments where bit-for-bit signal accuracy is required. As a static container for raw audio data, the format is considered inherently safe, although it has largely been superseded by more efficient compressed formats for general consumer distribution and mobile playback.
