The citation and abstract are below. Cheers, Bill Woods Principal Research Scientist Starkey Hearing Research Center Berkeley, CA V. Hohmann Frequency analysis and synthesis using a Gammatone filterbank ACTA ACUSTICA UNITED WITH ACUSTICA Vol. 88 (2002) 433 - 442 This paper describes an efficient implementation of the 4th-order linear Ga= mmatone filter [1, 2] based on an impulse-invariant, all-pole design. A linear auditory filterbank is constru= cted from these filters, which has been used in several applications involv= ing computational auditory peripheral filtering [3, 4, 5, 6, 7, 8, 9]. Addi= tionally, a novel approach to the recombination of the Gammatone filterbank= output is introduced that allows for the resynthesis of the signal with a = total time delay of 4ms. The signal reconstruction is nearly perfect, i.e.,= the difference between input and reconstructed output is barely audible. A= detailed technical description of the analysis-synthesis system is given a= nd an implementation using the Matlab programming environment is introduced= , which is available online. A possible application of the analysis/synthes= is system introduced here is speech processing for hearing aids. > -----Original Message----- > From: AUDITORY - Research in Auditory Perception > [mailto:AUDITORY@xxxxxxxx On Behalf Of Guy Brown > Sent: Tuesday, November 11, 2008 2:17 AM > To: AUDITORY@xxxxxxxx > Subject: Re: Phd copy request (Weintraub 1985) > > Dear Marc, > > I had a 1994 paper with Martin Cooke that explains the resynthesis > method (as you note, this was originally due to Weintraub).
