The latest update for both PC and Windows Phone adds support for Ogg Vorbis and Opus audio files! Ogg Vorbis is great for low bitrate compression, while Opus beats mp3 and others when using medium and high bitrates. So especially on the phone where storage space might be limited, these are two excellent options for compressing your audio files. Please let me know if you experience any problems with the new codecs! You need the Pro Version to play these formats.
If you already have Opus files in your collection, you will have to reset your music library in the app settings, to get them scanned and added correctly. Ogg Vorbis files should work without library reset.
Notice to Windows 8.x users:
Until now, I have tried to make all new features available on all platforms, even on Windows 8.0. But in this case, due to technical reasons the new codecs are only available on Windows 8.1 and higher. In the future, there might be more features which will only be added on Windows 8.1 and some even on Windows 10 only. If you still use Windows 8.0 or Windows 8.1 and want all the latest features in Music Mode, I would recommend you to consider using the free Windows 10 upgrade offer. Windows 10 is pretty mature by now, and it will be the last big Windows version for a very long time. So once you made it to Windows 10, you won’t need to install a new Windows version for a very long time. The free upgrade offer ends in about three months.
