Abstract :
An algorithm for high-quality coding of 48 kHz sampled audio signals is presented. The algorithm employs a perceptual transform and a variable-depth multistage quantizer. The resulting audio reproduction quality is better than that of the Motion Pictures Expert Group (MPEG) layer I coder and roughly equivalent to that of the MPEG layer II coder
