OptimFROG DualStream

OptimFROG DualStream is a lossy codec, aimed to fill gap between perceptual coding and lossless coding. 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.

This correction feature is also offered by WavPack and MPEG-4 SLS.
