Filter Bank

This function can be used to design a uniform filter bank (with M analysis and M synthesis filters) so that the perfect reconstruction is almost achieved. The method is based on the optimization technique proposed in [1].M= Number of subbandsm= A positive... Platforms: Matlab

The Analysis & Reconstruction Sound Engine also known as ARSE, is a program that analyses a sound file into a spectrogram and is able to synthetise this spectrogram, or any other user-created image, back into a sound. The ARSE consists in two main parts, a spectrographer with a base-2... Platforms: *nix

This set of files can be used to construct a polyphase filter bank with near perfect reconstruction. The filter bank is implemented using two uniformly modulated DFT filter banks that are frequency shifted by 1/2 channel width. Effectively, two-times oversampling is used.The number of channels...

Recent studies on Mathematical modeling of visual cortical cells [Kulikowski/Marcelja/Bishop:1982] suggest a tuned band pass filter bank structure. These filters are found to have Gaussian transfer functions in the frequency domain. Thus, taking the Inverse Fourier Transform of this transfer... Platforms: Matlab
