OptimFROG DualStream
OptimFROG DualStream is a lossy codec, aimed to fill the gap between perceptual coding and lossless coding as OptimFROG DualStream has an option to produce a correction file. This file can be used, in combination with the main lossy-encoded file, for lossless decoding, but not, unlike Wavpack hybrid for instance, for playback.[1]
This correction feature is also offered by MPEG-4 SLS and DTS-HD Master Audio.

Metadata
Both OptimFROG file formats use APEv2 tags to store the metadata.
gollark: > i wonder how much google can tell about some1 just from their viewing habitsWell, they probably combine those with a bunch of other data. Like location, stuff installed on phone, search history, that sort of thing.
gollark: I mean, I already watched the new one, so I suppose it has evolved beyond those advert recommendation systems which show you ads for stuff you already bought.
gollark: Huh, I just opened YouTube and the very first thing there was the IR death ray video, video.
gollark: Huh. That is a... vaguely worrying amount of information, but I guess Google does that.
gollark: (unfathomable is a great word)
