Libfilth is a library for designing, analysing, transforming and executing digital FIR and IIR filters.
The filter design methods include:
FIR filter with linear-phase, least-squares design.
FIR filter with complex specification, least-squares Design.
FIR filter with linear-phase, minimax-design using linear programming.
FIR filter with linear-phase, minimax-design using Remes algorithm.
FIR filter with minimum-phase and optimal amplitude.
FIR filter with complex specification, minimax-design.
FIR filter with group delay constraints.
FIR optimal window using quadratic programming.
FIR filter with minimum-phase by spectral factorisation.
FIR filter design by cepstrum technique.
Analog filter design Bessel-Thomson, Butterworth, Chebyshev type I, II and Elliptic function filter.
Transformation of analog to analog and analog to digital filters.
All-pass realization of IIR filters.
FIR half-band filters.
DFT filterbanks and parallel DFT filterbanks design and implementation.
Analysis functions for calculating the properties if analog, IIR and FIR filters.
