"This equalizer belongs to the rare plug-ins, which make music instead of sound...This plug-in is definitely one of my favorite devices, and it splendidly bears its name. Epure"

Epure v3 - Where Sound Becomes Music 

Epure v3 is a state-of-the-art five-band equalizer designed to provide the absolute finest audio quality within the domain of digital audio processing. Built with our proprietary State-Space technology, carefully tuned to preserve the optimal signal to noise ratio independent of the parameter settings preventing the signal from deteriorating when the gain is reduced, makes Epure v3 a powerful go-to processor for your day-to-day session work, as well as an efficient sharp-edged surgical precision tool for the most demanding equalizing and filtering tasks conceivable.

User Interface and Workflow

In addition to the supreme audio quality, the logical and comprehensive user interface includes a variety of instant shortcut functions provided to enhance and simplify the user workflow, allowing for instant and precise operation. Each of the five colour coded band sections is covering the complete frequency range and offers -/+ 24 dB gain with dynamic gain controls allowing you to multiply the gain by 2, divide it by 2, or invert the gain with just the flip of a switch.


As all Flux:: processors Epure v3 provide up to eight channels of simultaneous processing for multichannel/surround operations.

In addition, 4 MS decoders/encoders and up to 8 internally routable processing groups present the ability to process multiple explicit tiers from within one single plug-in instance, allowing for complex processing assignments such as separate processing of M and S components.

Using the internal processing groups and the MS option in a multichannel setup, you could for example have one set of controls grouped together for the front channels, with a different group controlling the rear channels, configuring an MS EQ on the front channels and simultaneously another MS EQ on the rear channels as well, using one single instance of Epure v3 only


Epure v3 Band Features:

  • Each of the five band-sections provides
  • Filter type selection
  • low cut
  • low shelving
  • peak
  • hi shelving
  • hi cut
  • Frequency range covering the whole bandwidth
  • Q factor adjustable (from 1.00 to 100.00)
  • Gain control (ranged -24 dB to +24 dB)
  • Bypass

Epure v3 User Interface Features:

  • To match the perfection of the sound quality of the Epure v3, we have provided a range of user interface functions to improve the workflow
  • Multiply gain (x2) affecting the gain value of the band-section
  • Divide gain (/2) affecting the gain value of the band-section
  • Invert, converting the band-section positive values to negative and vice versa
  • up to 8 band group

Signal Processing Features:

  • Master gain control
  • full I/O routing matrix
  • up to 4 MS encoder / decoder
  • Bypass routes the incoming signal direct to the output for a true smooth transition between processed and clean signal

Preset and Parameter Handling / Slots

To enhance the workflow the two Preset/Parameter slots, A and B, can be loaded with two full set of parameters at the same time. Apart from saving each preset, a "Global Preset" containing both the A and B settings, and the position of the "Morphing Slider", can be saved.

Parameter Morphing Slider with Automation

The Morphing Slider provides morphing between the parameter settings of slot A/B allowing for really creative and useful real-time tweaking. Enabling the Automation control button exposes the Morphing Slider to the host automation.
