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.
