  سند علمی۲۰۰۷Speech CommunicationHeinrich W. Löllmann, Peter Vary

  A versatile filter-bank concept for adaptive subband filtering is proposed, which achieves a significantly lower algorithmic signal delay than commonly used analysissynthesis filter-banks. It is derived as an efficient implementation of the filter-bank summation method and perfor

  This paper treats the problem of designing eecient FIR analysis-synthesis lter banks with system delays that can be pre-speciied. A framework is introduced that is comprised of the cascade of several distinctive matrices with invertibility properties. The explicit form of the mat

  The ISO-MPEG standards are widely used for high quality audio coding. They use perceptual models that require high frequency resolution. This implies two characteristics: they use high selectivity filter bank to decompose the audio signal, and the FFT frame length for the frequen
