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. |

Description | MP3 is the most popular audio file type based on MPEG-1 Layer III compression. Its lossy algorithm was developed in 1991. MP3 codes the sound almost with the same quality, as CD (16-bit stereo), providing compression in size 1 to 10 from the original WAF or AIFF tracks. The quality of MP3 seriously depends on the bitrate. It can be 128 - 256 kbps. Higher bitrates are also supported, but they seriously increase the file size. It is supported by all modern hard- and software players. |
