OptimFROG

OptimFROG audio streams with APEv2 tags.

OptimFROG is a lossless audio compression program. Its main goal is to reduce at maximum the size of audio files, while permitting bit identical restoration for all input. It is similar with the ZIP compression, but it is highly specialized to compress audio data.

Only versions 4.5 and higher are supported.
