This project intends to provide software for the generation of AC3 soundtracks. These soundtracks can be incorporated into videos, animations or as standalone dolby digital CD's.
Digital Audio Compression Standard Specification for coding audio data, used in DVD. The documentation is freely available . (bi-directional) picture Picture decoded from its own data, and from the data of the previous and next (that means in the future) reference pictures (I or P pictures). It is the most compressed picture format, but it is less fault-tolerant.
A compression coding method developed by Dolby Laboratories for multiple channels of audio, which can reproduce a maximum of 5.1 channels, namely, three channels for the front, two channels for the rear, and 0.1 channel (super-woofer) for low frequency reproduction.
AC3 file, a Dolby Digital audio file, can be found as the standard audio track on Digital Versatile Discs (DVD) and High Definition Television (HDTV). This coder has been designed to take maximum advantage of human auditory masking in that it divides the audio spectrum of each channel into narrow frequency bands of different sizes optimized with respect to the frequency selectivity of human hearing. This makes it possible to sharply filter coding noise so that it is forced to stay very close in frequency to the frequency components of the audio signal being coded. By reducing or eliminating coding noise wherever there are no audio signals to mask it, the sound quality of the original signal can be subjectively preserved. View AC3 Converter.
Short for Audio Codec 3, the original and more technical name for Dolby Digital (see Dolby Digital)
Audio Codec 3. This was the original and more technical name for Dolby Digital. Replaced by marketing mavens when they realized that Dolby's name was not in the title. Some RF modulated, 5.1-encoded laser discs were labeled as AC3. Later versions were labeled as Dolby Digital.
Enhanced Dolby Digital sound. If you have used a digital-optical lead to connect your set-top unit to audio equipment with Dolby Digital decoding capabilities, you can select this option for enhanced sound.
Dolby udio oding lgorithm which selectively remove noise from specific frequency bands.
A compressed audio signal used on NTSC-formatted DVDs, providing up to six separate channels of digital sound (file extension: .ac3). Also called the Dolby Digital Surround Sound System.
