OFR, short for OptimFROG, is proprietary lossless audio data compression codec created by Florin Ghido. OFR aims to optimize the high compression ratios and the price of slower encoding and decoding as well. OptimFROG DualStream which aims to fill gap between perceptual coding and lossless coding is another format of OptimFROG file, both of which could store the metadata by using PEv2 tags.
