Comment Ogg/Opus is Vorbis' successor (Score 4, Informative) 148
The Ogg container format is extremely versatile. Just look at what it can do with metadata compared to any other format.
The Opus codec supports up to 255 channels and sounds very good at lower bitrates compared to others.
And it's all F/OSS. I don't think there's anything else out there today that can claim all of these things at the same time.
