A faster filter and filtfilt: speedup factor 2.5 to 25 in matlab

The following Matlab project contains the source code and Matlab examples used for a faster filter and filtfilt: speedup factor 2.5 to 25 . FilterM, FiltFiltM: Fast digital filter These functions are compatible to MATLAB's FILTER and FILTFILT commands, but they are faster (see screenshot):   FilterM: 30%-40% of FILTER runtime   FiltFiltM: 4%-20% of FILTFILT runtime ADDITIONAL FEATURES: - The dimension to operate on can be specified for FiltFiltM.

Filter bank design in matlab

The following Matlab project contains the source code and Matlab examples used for filter bank design. The goal is to design M analysis and synthesis FIR filters so that the analysis filters satisfy some frequency specifications and the filter bank(almost) meets the perfect reconstruction (PR) conditions.

Audio filter in matlab

The following Matlab project contains the source code and Matlab examples used for audio filter. Simulates an audio filter by reading a wave file, applying the filter, and displaying the filter input and output on a scope while playing the filter output through the computer sound card.
