| 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.

| Developer | Xiph.Org, IETF |
Opus is a free, open-source audio codec developed by Xiph.Org and the IETF, standardized in 2012 (RFC 6716). It supports bitrates from 6 kbps to 510 kbps, covering both low-bitrate voice calls and high-quality music streaming with a single codec. Opus consistently outperforms MP3, AAC, and Vorbis at equivalent bitrates in independent listening tests. It is used by YouTube, Spotify, Discord, WhatsApp, Zoom, and WebRTC applications. Opus is natively supported in Firefox, Chrome, Edge, and most modern media players including VLC, MPV, and foobar2000, across Windows, macOS, Linux, Android, and iOS.
