Ogg Vorbis is a program designed to compress audio files in Vorbis format, which is similar in functionality and quality to such codecs as AAC, AC3 and VQF, but has a higher compression ratio than MP3. However, compression with this program can be accompanied by loss of sound quality.
One main benefit of using Ogg Vorbis is its superior compression ratio to MP3, allowing for high-quality audio in a smaller file size.
