FabFilter Pro-Q 3 is an EQ plug-in with up to 24 bands, analog modeling, dynamic EQ, linear phase processing.

FabFilter Pro-MB is a multiband dynamics plug-in featuring an optimized workflow: up to six compression/expansion bands can be placed freely anywhere in the spectrum.

Visual EQ Console is a multi-band EQ console with the ability to analyse audio in real time giving a spectrum representation of the frequency response. 

The JAF Collection is an exciting set of digital modeled classic analog synthesizer filters (VCFs) for iOS.

The MODEL ONE is a selected, fine-tuned general purpose (transistor ladder model) filter with the ability of strong self oscillation. The cutoff slope is approximately 24dB. It can be switched to low pass or high pass processing mode.

ToneBoosters Equalizer is a dynamic equalizer plug-in.

Knorr is a plugin that adds intensity and edge to a monophonic low frequency audio source (like a bass). The algorithm adds overtones to an existing sound in a way that isn’t possible with ordinary distortion or filtering.

FD-1 is a Semi-Modular Effect Plugin including dedicated Filter, Delay and Modulation sections.

PolyIvoks Filter developed on the basis of the filter of the legendary Soviet synthesizer from 1980s, and only now the legendary Soviet analog sound became available in stereo mode.

In the '80s it was the first to use a different approach to tonal adjustments. In conventional analog equalizers, whether they are shelving, sweepable, graphic or parametric types, various sections of the audio spectra are boosted or attenuated by adding or subtracting bandpasses. In this case, frequency shaping is achieved by summing bandpasses.
