Whenever you want to convert OFR to AC3, our smart OFR to AC3 Converter is your best choice.
OptimFROG(OFR) is a free lossless audio codec, known by its very high compression ratios. OptimFROG is developed by Florin Ghido. OptimFROG usually obtains the best lossless audio compression ratios on comparisons against other lossless encoders (practically a tie with the current champion LA). It has Windows and Linux versions, fully-featured input plug-ins for the foobar2000, Winamp2, Winamp3, dBpowerAMP, XMPlay and XMMS audio players (with bitstream error resilience, ID3v1.1 and APEv2 read tagging support), optimal support for all integer PCM WAV formats up to 32 bits and an extensible streamable (error tolerant) compressed format.
Dolby Digital AC-3 is the common version containing up to six discrete channels of sound. The most elaborate mode in common usage involves five channels for normal-range speakers (20 Hz – 20,000 Hz) (right front, center, left front, rear right, rear left) and one channel (20 Hz – 120 Hz allotted audio) for the subwoofer driven low-frequency effects. Mono and stereo modes are also supported. AC-3 supports audio sample-rates up to 48 kHz. Batman Returns was the first film to use Dolby Digital technology when it premiered in theaters in Summer 1992. The Laserdisc version of Clear and Present Danger featured the first Home theater Dolby Digital mix in 1995.
