When a sync pattern is detected, the decoder may be estimated to be in sync and one of the two Cyclic Redundancy Check words (crc1 or crc2). Image Courtesy () Synchronization and error detection Thereafter, the exponents and mantissas are converted back into the time domain to extract the decoded PCM time samples. Decoding of the spectral envelope results in the exponent’s values. At the decoder, the bit allocation module execution results in unpacking and de-quantization of the mantissa values. The bit allocation module is designed to calculate the number of bits required to encode each transform coefficient mantissa value on the encoder side. The decoder must synchronize with the encoded bit stream, check for errors, and de-format the various types of data such as the encoded spectral envelope and the quantized mantissa. It supports data rates ranging from 32 kbps to 640 kbps. The AC3 bitstream specification allows sampling rates of 48 kHz, 44.1 kHz, and 32 kHz. The six-channel configuration consists of the left channel, center channel, right channel, left surround, right surround, and subwoofer.
Surround sound consists of stereo channels and two surround channels (left and right), and a subwoofer, all of which are put together from the 5.1 Channel configuration.Conventional Stereo Channel (Mono+Mono or Stereo), and.The configurations supported by Dolby AC3 are: The AC3 algorithm can encode multiple audio channel formats into a single low-rate bitstream.
