01Overview

UNFILTER Educational Version is Zynaptiq's adaptive plugin for linearizing the frequency response of a signal. It analyzes audio as it plays and builds a filter that undoes resonances, comb filtering, equalization and roll-offs, using a single main control. The plugin also includes a free-form EQ, a 7-band graphic EQ and a steep high-pass filter, so it can handle both repair and tonal shaping tasks.

Automatic Frequency Response Correction

UNFILTER listens to the audio and estimates what has changed its frequency response. It then creates a filter to reverse that change. According to Zynaptiq, this runs in real time and is designed to leave the rest of the signal largely untouched.

The plugin can also apply a measured filter response from one recording to another, which helps place two sources in the same acoustic space. Measured responses can be exported to or imported from linear- or minimum-phase impulse response WAV files, so you can keep a library of filter responses for reuse.

EQ Tools and Workflow

Beyond automatic correction, UNFILTER includes an adaptive program equalizer that keeps adjusting while audio plays, a free-form EQ with several curve interpolation modes, and a 7-band graphic EQ. A 96 dB per octave shelving high-pass filter handles low-frequency rumble.

An output limiter is included for unsupervised batch processing. The developer describes the interface as fast and built around one main control for most corrective work, with finer settings available for advanced editing.

What formats and operating systems does UNFILTER Educational Version support?

It is available in VST3, VST2, AU and AAX formats for both Windows and macOS. The plugin is 64-bit.

What do I need to use UNFILTER Educational Version?

You need a compatible host that supports VST2.4, VST3, AU or AAX and processes audio as 32-bit float. An iLok account and an internet connection are required for activation. Zynaptiq recommends a buffer size of at least 512 samples, ideally 1024.

Can I try UNFILTER before using the educational version?

A free trial is available. Zynaptiq notes that its plugins use a lot of CPU, so the trial is a good way to check whether your system can run the software effectively.
