apeFilter is a sophisticated Equaliser, the DSP is based on the Biquad/Cascade filters, very fast! The graphical interaction provides a great tool to design an extremely precise and smooth frequency response by directly manipulating up to 36 Peaks Filters. The Spectral Grid compilers increase the complexity and coherence between the filters bandwidth space. You can create your pitch space by the way of four different criteria of construction by determining a pitches grid: Fibonacci, Harmonic, Geometric and Scalar. Use apeFilter for sculpt your sound through the embedded sampler or LIve from Audiobus or Inter-Audio-App Input. Among the FX chain, an amazing ClassicVerb is available.

Rich and Musical, Alien Filter

This is yet another bit of magic from Apesoft. With Apefilter, they've taken the standards of filter functionality/architectures, and expanded/extended these features into new realms. The results are refreshingly rich and musical.
The highlight (for me) - the ability to distribute the frequency ratios of multi-band / resonant filters - it offers numerous mathematical / harmonic ratios, with a variety of parameters to modify and customize the distribution. The depth of functionality here is unmatched. One can completely alter the timbre and character of a sound, with surprising and rewarding results.
As always, the built-in modulation / LFO per parameter adds another potent layer for manipulation and sound design.

Great tonal control

Top notch well designed total frequency control for sound engineers. Pretty sure it has good midi, but it keeps me busy enough already manually exploring it's sensitive complex options.

Amazing app!

Incredible peak multi-filter implementation. If you are sick of standard high/low-pass closings/openings in your FX here is a new universe for you to explore.
