The UNFILTER Black Friday deal covers Zynaptiq's real-time restoration plugin, with 63% off and a price of $99, running until Nov 22, 2026.
UNFILTER removes filtering effects from a signal: comb filtering, resonances and excessive EQ. It linearizes the frequency response automatically, so you don't have to hunt for the problem frequencies by ear.
The maker says it works for music production, film post, game audio, broadcast, sound design, forensics and engineering.
The plugin analyses your audio, estimates what happened to its frequency response, and builds a filter that undoes it. Zynaptiq describes the process as real-time blind de-convolution.
Once a problem is detected, you remove it with a single control. The rest of the signal is left virtually untouched, according to the maker.
Yes. The maker calls it three mastering-grade EQs plus a high-pass filter.
The first is an adaptive program EQ. It keeps adjusting while audio plays, which helps hold a balanced spectrum on material that changes over time, such as mixed music streamed in broadcast.
The second is a free-form EQ with several curve interpolation modes, from very gentle slopes to narrow notches and brick-wall steps.
The third is a streamlined 7-band graphic EQ.
The high-pass filter is a shelving design with a slope of 96dB/octave, built to clear low-frequency rumble.
In audio post, Zynaptiq lists removing comb filtering from multiple open mics mixed to one track, taming room resonances and lav chest resonance, and helping ADR blend with production dialogue. You can also apply a measured response to noise to build room tone for editing gaps.
In music production and mastering, the listed uses include pulling resonances out of acoustic instruments and live recordings, and removing EQ printed into delivered tracks. You can strip guitar cabinet colouration or apply it to a DI guitar, and clear low-mid buildup from sub-mixes.
You can also capture the response of outboard EQ or another signal path and store it as an impulse response, building a library of colours to reuse.
The interface is built for speed. The maker says corrective EQ can often be done in seconds with one trackball slider, and a free trial version is available.
Yes. The UNFILTER Black Friday deal takes 63% off, bringing the Zynaptiq plugin to $99. The deal ends Nov 22, 2026. The restoration tool removes resonances, comb filtering and unwanted EQ from a signal in real time.
UNFILTER detects and removes frequency response problems such as resonances, comb filtering, roll-offs and excessive EQ. Zynaptiq says it suits music production, film post, game audio, broadcast, sound design and forensics, working on music, dialogue, location and surveillance recordings.
UNFILTER includes an adaptive program EQ that adjusts continuously during playback, a free-form EQ with several curve interpolation modes, and a 7-band graphic EQ. It also has a 96dB/octave shelving high-pass filter for removing low-frequency rumble.
Yes. It can apply a measured filter response to another signal, placing both in the same acoustic world. That helps ADR blend with production dialogue. Responses can also be saved or loaded as linear- or minimum-phase impulse response WAV files.
