The Ogg Vorbis format is an open-source, patent-free audio compression standard developed and maintained by the Xiph.Org Foundation. It is widely utilized for lossy audio streaming, video game sound effects, and digital music distribution because of its efficient variable bitrate encoding. As a safe multimedia format, it provides a royalty-free alternative to proprietary codecs, though it is now often superseded by the more advanced Opus codec for modern web-based audio.
