@catgirl I'd just like to interject for a moment. What you're referring to as OGG, is in fact, Ogg Vorbis or Ogg Opus. Ogg is not a format unto itself, but rather a container format suitable for a number of free codecs such as Vorbis, Theora, FLAC, Opus and others. Through a peculiar turn of events, the version of Ogg which is widely used today is often called “OGG”, and many of its users are not aware that it is Ogg Vorbis, developed by Xiph.org.
