The AIFF (Audio Interchange File Format) is an uncompressed audio file format known for its high-quality sound reproduction. Developed by Apple, AIFF files store audio data in a linear PCM (Pulse Code Modulation) format, preserving the original audio quality without any loss. Due to its uncompressed nature, AIFF files tend to be larger in size compared to compressed formats, making them suitable for professional audio applications where uncompromised audio fidelity is crucial. AIFF is commonly used in music production, audio editing, and multimedia applications within the Apple ecosystem.
