Opus, another after Vorbis audio codec developed by Xiph.Org Foundation is a widely used free internet standard (including YouTube). It seems to be at least as good as Vorbis at high bitrate and much better elsewhere. From Wikipedia: > Opus replaces both Vorbis and Speex for new applications, and several blind listening tests have ranked it higher-quality than any other standard audio format at any given bitrate until transparency is reached, including MP3, AAC, and HE-AAC. Therefor, maybe it would be good to do some order switching in the preferences dialog and replace Opus with Vorbis?
