AC-2: A Family of Low Complexity Transform-Based Music Coders
Two high-quality data rate reduction music coders from a family of TDAC transform-based coders are discussed. An overview of the psycho-acoustic principles used in their design is given and their limitations discussed. The use of psycho-acoustics and DSP technology are combined to yield a low complexity approach to music coding. Issues of complexity, word length requirements, and memory usage are examined for both general-purpose DSP and custom IC implementations.
