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.

You can also apply the measured filter response from one recording to another – placing the two in the same acoustic “world”. Or you can create room-tone to fill editing gaps, by applying a measured filter response to noise. You can of course also store filter responses to disk as linear- or minimum-phase impulse response files, building a library of “colors” to have at your disposal any time. Whether you need to make ADR blend with production dialog, get one guitar snippet to sound like part of another, or create new sounds, UNFILTER makes this task fast and easy.

UNFILTER is also an EQ. Three mastering grade EQs and an excellent high-pass filter, actually. For one, its (un-)filtering engine can function as an adaptive program equalizer that continuously adjusts itself while the audio is playing. This helps maintain a balanced spectrum when working with audio that changes over time, for example when streaming mixed music in broadcast applications. Secondly, UNFILTER sports a free-form EQ with various curve interpolation modes, from super-gentle slopes, through narrow notches, to brickwall steps. Thirdly, we added a streamlined 7-band graphic EQ for good measure. And finally, there’s a super-steep 96dB per octave shelving high-pass filter that removes low frequency rumble so efficiently you’ll forget that there was ever anything down there.

How does UNFILTER do all that? Technically, it performs a real-time blind de-convolution, a cutting-edge technology rarely found even in the most advanced of research institutes. Fortunately, we don’t do lab coats.
This technology allows UNFILTER to take a close look at your audio, estimate what happened to its frequency response, and then create a filter that will undo the process. Sounds like rocket science? That’s because it is. But all the technology in the world doesn’t matter if it’s difficult to operate or doesn’t sound good. Well, UNFILTER is a breeze to use, and doesn’t just sound good…it sounds amazing.

The UNFILTER UI is so fast and easy to use that corrective EQ can often be done within seconds by adjusting just one of our super-slick trackball sliders. And for advanced customization, every single function and control has been engineered with painstaking attention to detail – finely-tuned for optimal workflow and results. Whichever control you move, the right setting is never far away. UNFILTER is not only a life-saver, it is also a time-saver par excellance.
