AC3 is the audio codec used in Dolby Digital, a surround sound standard developed by Dolby Laboratories and introduced in 1991. AC3 files typically carry up to 6 audio channels — front left/right, center, surround left/right, and a low-frequency effects (LFE) subwoofer channel — commonly known as 5.1 surround sound. The format is widely used on DVDs, Blu-rays, and digital television broadcasts. An AC3 stream can be stored as a standalone file or embedded in video containers such as MKV, AVI, or VOB. Supported by VLC, Kodi, foobar2000, and most modern home theatre receivers.

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.
