UNFILTER is a real-time audio plug-in designed to eliminate filtering effects like comb filtering, resonance, and excessive equalization by automatically linearizing the frequency response of any signal. It excels at removing unwanted tonal coloration and restoring natural sound, making it ideal for refining musical recordings, dialogue, and field recordings. The plug-in can also extract and apply detected filter responses to other audio sources, enabling seamless blending of different sounds or environments.

In addition to its automatic correction features, UNFILTER supports exporting and importing filter responses as impulse response files for further processing or use in other applications. Its mastering-grade adaptive equalization tools include free-form and graphic EQ options, along with a steep shelving high-pass filter and an output limiter for safe batch processing. This combination of features makes UNFILTER suitable for tasks such as reducing room resonance, enhancing speech intelligibility, rebalancing mixes, and creatively shaping sound textures.

UNFILTER is available in AU, RTAS, AAX Native, and VST formats for both Mac and Windows platforms, ensuring broad compatibility with major digital audio workstations. Its efficient workflow and user-friendly interface support fast, high-quality audio restoration and equalization in professional production environments. A free trial version is offered, allowing users to experience the plug-in’s powerful capabilities firsthand before purchase.
