Super Bit Mapping: Psychoacoustically Optimized Digital Recording

Document Thumbnail

Super bit mapping uses psychoacoustic principles and critical band analysis to maximize the sound quality of 16-bit digital audio. 20-bit recordings are quantized to 16 bits using an adaptive error-feedback filter. This filter shapes the quantization error into an optimal spectrum as determined by the short-term masking and equi-loudness characteristics of the input signal. Through this technique, the perceptual quality of 20-bit sound is available on a standard compact disc.
