Adaptive Tonal Contour Linearization

UNFILTER is a real-time plug-in that removes filtering effects, such as comb filtering, resonance, or excessive equalization – effectively linearizing the frequency response of a signal automatically.

UNFILTER can also apply a detected filter response to another signal, or export it to disk as an impulse response, and can even perform mastering grade adaptive, free-form, and graphic equalization.

Whether you're in music production, film post, game audio, broadcast, sound design, forensics, or engineering – UNFILTER makes time-consuming and often impossible tasks as effortless as adjusting one control.

UNFILTER automatically detects resonances, EQ or filter effects – essentially any frequency response anomalies that aren't part of the original signal. You can then remove these by simply adjusting one control, leaving the rest of the signal virtually untouched. As a result, previously problematic or unusable recordings can be made to sound good, and good recordings to sound great. In real-time, and with minimal effort, Zynaptiq-style.

The free v1.3.0 update includes over 150 new presets, a brand new preset manager, increased resolution for numerical parameter entry, and more.

Main Features

• Automatically detect and remove resonances, equalization, roll-offs and the effects of comb filtering from musical, location, dialog and surveillance recordings.
• Apply the measured filter response to other signals to place them in the same "acoustic world".
• Export the measured filter response to or import it from a linear- or minimum-phase impulse response file (WAV).
• Mastering grade adaptive, free-form and graphic equalization.
• Extremely steep 96dB/octave shelving high-pass filter.
• Output limiter for unsupervised use in batch processing applications.
• Highly time-efficient workflow and UI
