FIREQ is a 1/6th octave stereo Finite Impulse Response (FIR) mastering equalizer with linear phase characteristics.

Its results are without non-linear phase shift or smearing of your audio. Improvements over RNDigital’s Frequal-izer (that it replaces) include 62 EQ bands with gain/reduction of +/- 27 Db per band-for precise frequency tailoring, an overall output gain/reduction range of +/- 24Db, and a larger, easy to read interface, according to RNDigital.


  • Linear phase mastering EQ.
  • 62 Bands.
  • +/- 27 db cut and boost.
  • Supports sampling rates up to 192 kHz.
  • Spectrum Matching.
  • Automation support (using States).
  • Work with each channel individually.
  • Four channel linking modes:
    o Lock – edit the left and right together.

    o Reverse – edits to one channel cause a reverse effect on the other (used with Weak or Strong).
  • Dynamically change the width of an EQ curve.

FIREQ LE is a 1/3rd octave stereo finite impulse response (FIR) mastering equalizer with linear phase characteristics. This new equalizer from RNDigital incorporates the same filter characteristics of FIREQ, but does not allow for spectral matching or the use of states.
The layout of the FIREQ LE includes 31eq bands with gain/reduction of +/- 27 Db per band, freehand curve drawing, extensive history, left/right channel linking and editing, a detailed customizable spectral display, two workspaces and an overall output gain/reduction range of +/- 24Db.

Pricing & Availability
Both products are now available as downloads from RNDigital web site. FIREQ costs $249, FIREQ LE $129.
Owners of Frequal-izer get FIREQ for free.
Presets saved and loaded from Frequal-izer into FIREQ will be offset due to the increase in control points.

Both plug-ins are available for Mac OS X (10.2+), Windows XP and Vista in VST, AU and RTAS formats.
