What is AIFF?
AIFF (Audio Interchange File Format) is Apple's uncompressed audio format, equivalent to WAV on Windows. It stores raw audio data at full quality.
AIFF files are used in professional audio production but are impractical for everyday sharing due to their enormous file size.
What is MP3?
MP3 compresses audio using psychoacoustic modeling to remove sounds the human ear cannot easily perceive.
MP3 files are typically 10x smaller than AIFF while maintaining excellent perceived audio quality for most listeners.
