OptimFROG is a proprietary lossless audio data compression codec developed by Florin Ghido. OptimFROG is optimized for very high compression ratios at the expense of encoding and decoding speed.

OptimFROG DualStream[edit]

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.

Technical details[edit]

Metadata[edit]

Both OptimFROG file formats use APEv2 tags to store the metadata.
