License: MIT Description: C++ implementation of equalization filters based at "High-Order Digital Parametric Equalizer Design" by Sophocles J. Orfanidis Dependencies: https://github.com/thedrgreenthumb/MDSPTK Needed for MATLAB test bench. Implemented next filters types: Butterworth Chebyshev Type 1 Chebyshev Type 2 Elliptic Classes description: eq - every channel consist of set of precomputed filters, where every filter computed for single gain value. See Usage guide below. How to run: Run test_orfanidis_eq.m script using MATLAB or $ python ./test_orfanidis_eq.py The four plots for every filter type should appear. Usage guide: //Create frequency grid and equalizer objects freq_grid fg; freq_grid.set_N_bands(); eq equalizer(fg, filter_type); //Set gains for every band equalizer.change_gains(); //Sample by sample processing equalizer.sbs_process();
