Zynaptiq UNFILTER - Adaptive Tonal Contour Plug-Infrom Zynaptiq UNFILTER - Adaptive Tonal Contour Plug-Inis a versatile frequency response tool with a broad range of applications. The real-time plug-in is able to automatically remove filtering effects, such as comb filtering, resonance, or excessive equalization. Applications include audio post for film sound, music production and mastering, broadcast and ENG, sound design, and forensics. The plug-in can also apply a detected filter response to another signal, or export it to disk as an impulse response.

When doing post-production for film sound, the automatic recognition of frequency response anomalies is extremely useful for cleaning up production sound, and especially for enhancing the intelligibility of dialog. In music production and mastering, fine-tuning the frequency response of a signal is one of the most commonly encountered tasks. While recordings of acoustic instruments and live performances can often exhibit unwanted peaks and notches. Here the high-precision filtering engine makes it a very flexible solution for these issues.

For broadcasting audio, it is important to maintain a consistent and balanced audio spectrum, to ensure optimal performance of all down-stream systems, and to provide a high-quality, consistent and non-fatiguing listening experience to the audience. As the acoustic properties of the footage used can vary strongly to say the least, this is no trivial task. Electronic News Gathering (ENG) often requires using small, portable and inconspicuous devices, and/or low bandwidth transmission systems. The software's adaptive processing aids in making even the most difficult footage usable.

The ability to completely reshape the spectral contour of a signal, extract the filter response from a sound and apply it to a different file, and to solo the noisy components contained in a sound makes it an excellent tool for designing new sounds. When applied to the field of forensics, the plug-in can assist in extracting information from recordings in multiple ways. Intelligibility of speech recordings can be greatly enhanced, the filtering effects of microphone occlusion can be removed, and sounds buried beneath others can be made more audible.
