Zynaptiq Unfilter

Description

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.
Set It Straight

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.

Make It So

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 “colours” to have at your disposal any time. Whether you need to make ADR blend with production dialogue, get one guitar snippet to sound like part of another, or create new sounds, UNFILTER makes this task fast and easy.

More Equal

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 brick wall 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.

Features

• Automatically detect and remove resonances, equalization, roll-offs and the effects of comb filtering from musical, location, dialogue 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

Important Notes: An iLok account or iLok 2/3-based activation is required in order to register this product. An internet connection is required for software activation.

Copy Protection

Zynaptiq products use the latest PACE copy protection, which allows you to place your activation on your machine or on an iLok 2* (not included). You will need a free iLok.com account to use our software, even for the demos – but you do not necessarily need the iLok 2 dongle if your machine has internet access (activation of a system without internet connectivity requires an iLok 2 device). All required software is installed along with our plugins, but we generally recommend downloading the latest versions directly from iLok.com.

Please Note: The older, first-generation iLok is not supported!

CPU Load

While they are highly optimized, Zynaptiq plugins use a LOT of CPU due to the complex nature of the magic they perform. Please use the free trial to evaluate whether your system has sufficient resources to utilize the software effectively!

Zynaptiq recommends setting your playback buffer size to at least 512 or ideally 1024 samples for optimum performance.

As Zynaptiq plugins sport unique features not found in any other software, Zynaptiq highly recommends reading the User Manuals to ensure that you get the most out of them!
