AIFF — Audio Interchange File Format
| File extension | .aiff .aif |
|---|---|
| File category | audio |
| Programs | Apple iTunes Apple QuickTime Player VLC media player Audacity Logic Pro |

| Developer | Apple Inc. |
AIFF (Audio Interchange File Format) is an uncompressed audio container developed by Apple Inc. in 1988, based on EA IFF 85. AIFF stores raw PCM audio without compression, preserving full audio fidelity — one minute of stereo CD-quality audio (44.1 kHz, 16-bit) occupies approximately 10 MB. The format supports sample depths from 8 to 32 bits and sampling rates up to 192 kHz, making it a standard choice for professional audio production on macOS. AIFF is natively compatible with Apple iTunes, Logic Pro, GarageBand, and most professional DAWs. An extended variant, AIFF-C (AIFC), supports optional compressed audio codecs.

| Developer | Fraunhofer Society |
MP3 (MPEG-1 Audio Layer 3) is a lossy audio compression format developed by Fraunhofer IIS in Germany and standardized in 1993. It achieves compression ratios up to 10:1 by removing audio data deemed imperceptible by the human ear, using a psychoacoustic model. Users can set the bitrate — typically 128 to 320 kbps — to balance file size and audio quality. MP3 is the world's most universally supported audio format, compatible with virtually every media player, smartphone, smart TV, and car audio system. Despite newer alternatives like AAC and Opus offering better quality at the same bitrate, MP3 remains the standard for music distribution and storage.
