Description | The inception of the OFR (OptimFROG) audio format is but another win against the ‘tyranny’ of MP3. OFR uses a lossless compression algorithm and high file size reduction (by 30-70%). The extent of compression depends on the density of audio data. Therefore, hard rock tracks require deeper compression than folk or classical tracks. Encoding is very fast: for AMD Athlon XP +1800, the real-time encoding speed for CD is 12.4x, and the real-time decoding rate is 17.4x. The format is supported by Windows and Linux. |
