Re: [Trisquel-users] Opus and Ogg Vorbis in IE11 push

Yeah, I guessed that Opus was the best solution to get royalty free audio  
codecs in Internet Explorer considering Opus uses the SILK codec (created by  
Skype, for which MS owns) in addition to Xiph.Org's CELT. They even own  
patents to it, so it doesn't hurt them to include technology they own:  
http://opus-codec.org/license/

"Microsoft acquired patents and applications related to Opus through their  
purchase of Skype. These patents (and any other Microsoft might have had) are  
available under a different, but still royalty-free, license detailed below.  
The license covers the listed patent applications, along with any other  
patent or application covering Opus that is owned by Microsoft."
