Acustica Audio has released Fire Filters, a pair of filter plug-ins designed for easy one-knob operation. With a variety of modes and slopes to choose from, Fire Filters pairs plenty of sonic versatility with a quick and easy interface. The two filters are the first plug-ins in Acustica’s new Fire Series, which will be expanded with more one-knob plug-ins in the future.
Acustica Audio Fire Filters
Acustica says that the new Fire series is meant to combine high audio quality and a distinctive sound with an intuitive, easy-to-use interface that delivers quick results. To achieve this, they’ve emulated “the best audio processors built with the best components” and put them into a new series of one-knob plug-ins, each with a set of essential options.
The two Fire Filters are the first plug-ins in the new series. Acustica says that the high-pass and low-pass filters are based on an analog modular hardware filter, which they’ve built and sampled.
These being “one-knob” plug-ins, each filter offers a huge cutoff knob (10 Hz to 6.3 kHz) as the main control. But you do have some options. The high-pass and low-pass filters both offer a choice of four slopes (6, 12, 24 and 36 dB/octave). With the exception of the 6 dB slope, they can also operate in four modes: Bessel, Butterworth, +2dB resonance peak, and +6 dB resonance peak. This means that while you don’t get a continuously adjustable resonance control, you do have a few settings to choose from for added sonic variety. All in all, each of the two filters offers 13 possible combinations.
While one-knob plug-ins like these offer limited tweakability, they can deliver quick results if you want to keep the creativity flowing. It’ll be interesting to see the Fire series grow – which other one-knob processors could Acustica have in the works?
