DEKODNING AF FLERKANALAUDIO-KODEDE BITSTRØMME VED ANVENDELSE AF ADAPTIV HYBRID TRANSFORMATION

摘要

The processing efficiency of a process used to decode frames of an enhanced AC-3 bit stream is improved by processing each audio block in a frame only once. Audio blocks of encoded data are decoded in block order rather than in channel order. Exemplary decoding processes for enhanced bit stream coding features such as adaptive hybrid transform processing and spectral extension are disclosed.
