摘要: Accurate measures of estimated spectral power and phase are derived from two representations each one or more input signals generated by critically-sampled filter banks. The may be used in various applications including adaptive bit allocation perceptual coding systems. An efficient implementation particular single-sideband bank is disclosed.
