It's very cleanly done, and the multiple artwork idea is fantastic. One suggestion: I couldn't find an example in the man pages or online of including album art in an .opus file, which would have been helpful.</div><div><br></div><div>2) on the metadata topic, it'd be great if multiple Genre commands were allowed. No other format has enabled this, but much music spans multiple genres, ether with a main-genre/subgenre split, or literally across two genres. Ie: "Latin Music/Tango" or "Classical/Baroque"</div><div><br></div><div><div>3) audio quality is spectacular, and I assume that opus is doing something tricky with stereo compression to achieve such fidelity at this bitrate. Encoding speed was very good, with 1600 albums encoded in 24h on a not-very-modern machine.</div></div><div><br></div><div>4) In case you don't know Magnatune, we're an open-source friendly music collection, DRM free, offering unlimited downloading for members in various formats (mp3/wav/alac/flac/ogg/opus), with Creative Commons licensing applied to members' files as well. Linux users account for 29% of our daily traffic.</div><div><br></div><div>I blogged about this to my user base (28,000 people on my newsletter) and noted that the VLC playback of opus is flawless:</div><div><a href="http://blog.magnatune.com/2013/09/opus-format-audio-files-now-available-at-magnatune.html">http://blog.magnatune.com/2013/09/opus-format-audio-files-now-available-at-magnatune.html</a></div><div><br></div><div>I'd be happy to provide audio files to the project under CC terms, if they could help you demo/show off the quality of your work.</div><div><br></div><div>-john</div><div><br></div></body></html>
