OptimFROG is a proprietary lossless audio data compression codec developed by Florin Ghido. OptimFROG is optimized for very high compression ratios, even for the price of slower encoding and decoding.

OptimFROG DualStream[edit]

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 Hybrid, MPEG-4 SLS and DTS-HD Master Audio.

Technical details[edit]


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