"""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.
|
|
|
