Filter Section

X-EQ may well provide all the different EQ options you will ever need.

A total of 10 EQ bands are provided, split into dedicated HP and LP filters, LF and HF shelves and 6 bell bands. In addition to this, various filter types are provided independently for each of the 10 bands. The HP and LP filters have 5 different topologies available, the 6 bell bands provide a total of 9 different characteristic shapes and the LF and HF shelving filters offer variable Q. Together these cover the vast majority of EQ styles currently popular amongst professional users, including some legacy styles which are renowned for their artistic capability and some unique designs only possible in the digital domain.

FFT Spectrum Analyser

A real-time FFT analyser engine reports the amplitude of all frequencies at any moment in time. As the analyser is placed post-EQ, you can see what effect the processing has on the frequency spectrum. The Spectrum Analyser makes it easy to spot an offending frequency that needs attenuating, or a range of frequencies that require boost.

The analyser graphic can be turned on and off with the ‘Analyser’ button.

Parallel Button

Recreates the passive LC parallel equalizer with all its advantages (sound) and disadvantages (band interaction, asymmetry). Used in old or newly re-created Graphic EQs built with inductors and capacitors.

Parallel EQ exhibits quite different sonic properties to the familiar serial parametric EQ. A passive EQ does not have any gain elements, but can still have controls to seemingly boost frequencies as well as cut. What actually happens is that the entire signal is cut by an amount, but the frequencies which are apparently ‘boosted’ are simply not cut as much. Therefore the unit must attenuate either the input, the output, or both to allow enough headroom. Unfortunately in the analogue domain, a 20dB reduction in signal level produces a 20dB increase in the noise floor. Luckily, in the digital domain at 40 bit floating point these issues do not remain. The noise floor can be disregarded due to the huge resolution allowed by Duende.

Preset Management & A/B Functionality

Proprietary preset management functions provide compatibility between all DAW platforms.

A/B functionality, providing two different memory locations, is included for easy comparison of any two settings.
