The Xiph.Org Foundation maintains three of the most widely deployed open-source audio codec libraries in the world: <strong>libopus</strong> for interactive speech and general audio, <strong>libflac</strong> for lossless archival, and <strong>libvorbis</strong> for general-purpose lossy compression. Together, these libraries power everything from Discord voice chat to Spotify streaming to FLAC music archives.</p>
