This directory contains a Matlab implementation of the gammatone filterbank described in V. Hohmann's Paper `Frequency analysis and synthesis using a Gammatone filterbank', published 2002 in `acta acustica'. copyright: Universitaet Oldenburg author : tp date : Jan, Apr 2002 filename : README.txt This is a pure Matlab implementation. Its focus is on readability of the source code rather than performance. (Alternatively, the filterbank analysis is also implemented in C, and can be called and used in place of the Matlab function). All parts of the implementation will also work with Octave, a free interpreter that is largely compatible with Matlab (see http://www.octave.org/). Documentation ============= README_implementation.txt: Introduces the design principles behind this implementation, and containes a list of the implemented Matlab functions. README_examples.txt: Explains where to find the specific implementations and how to execute the examples promised in section 5 of the `acta acustica' article. README_extension.txt: Explains how to compile and use the filterbank analysis function written in C, to speed up calculation with respect to the analysis performed with native matlab/octave functions. ----------------------------------------------------------------------------- Copyright (C) 2002 AG Medizinische Physik, Universitaet Oldenburg, Germany http://www.physik.uni-oldenburg.de/docs/medi Permission to use, copy, and distribute this software/file and its documentation for any purpose without permission by UNIVERSITAET OLDENBURG is not granted.
