Comment 19 for bug 57797

> Also, according to listening tests, opus is known to be better than vorbis in every tested scenario, see: http://jmspeex.livejournal.com/13547.html

I can say from the experience of ABX testing classical music at low bitrates, 32 kb/s to 64 kb/s, that there's basically no comparison between AoTuV and Opus, in that AoTuV performs vastly better. That can be important for devices with limited storage, like smartphones. I know Xiph consistently claims Opus to be superior, but I've had a very different experience with the music I've tested, and in any case, this isn't a question of Opus vs. AoTuV. This is a question of the latest AoTuV vs. an old version, and we know which is better.

I understand that getting the patch applied upstream would be preferred, but realistically, that's not going to happen. This has been a known issue in Debian for years, and nothing has been done about it. It's a simple enough patch to apply that I would say Ubuntu should just go ahead and do it.
