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.
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.
