    This audio file container was created by Apple's developers. CAF can store a lot of information: the artist's name, song duration, album and track names, and more. In terms of size, CAF files can exceed 4 GB. Since its introduction in 2005, the Core Audio Format has been used as an alternative to AIFF and WAV. It can use different codecs, so audio quality depends on the chosen encoding. CAF files are often used to store audio assets and sound effects.

    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.
