The goal of CamillaDSP is to provide both FIR and IIR filtering for Linux, Windows and macOS, to be stable, fast and flexible, and be easy to use and configure. BruteFIR: https://torger.se/anders/brutefir.html EqualizerAPO: https://sourceforge.net/projects/equalizerapo/ The IIR ...
Since the filter has no feedback, many more coefficients are needed in the system equation to meet the same requirements that would be needed in an IIR filter. For every extra coefficient, there is an extra multiply and extra memory requirements for the DSP. For a demanding system, the ...

Controls whether the filter automatically sets the output word and fraction lengths, product word and fraction lengths, and the accumulator word and fraction lengths to maintain the best precision results during filtering. The default value,FullPrecision, sets automatic word and fraction length determinat...
The IIR filter has a similar form as (1) with k−N replaced by the initial time k0. For IIR and FIR filters, initial states are denoted by xk0 and xk−N, respectively. It is noted that the linear FIR filter (1) does not include an initial state term and its gains Hk−i,...

IIR filters. They provide a constant group delay for all the frequencies and have better performance with fixed-point implementation when compared to IIR filters. These advantages make them a popular choice in many applications. Previous work on the review of VCF FIR and IIR filters can be ...
For full correspondence with "filter" you should use IPP IIR functionality and recalculate zi (delay line) to direct form 2 as it's described in Matlab documentation (ippsIIR also uses direct form 2 delay line). Or if you need only FIR - you should use your direct form1 delay line ...
