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.

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.
