Product description

gEQ12 is a 12 band stereo/MS graphic equalizer with accurate spectrum analyzer and minimum/linear phase modes.

Today's mixing and mastering processes require a full featured but easy to use equalizer which can accurately shape the tone of a track , bus or master track.

gEQ12 provides all necessary tools including perceptual loudness matching in one package paired with some unique features.

Extended view

The spectrum/filter view can be enlarged and enriched with a spectrogram, a frequency tracker and several EQ cheat sheets.

Filter parameter

gEQ12 consists of 12 stereo filter in series. Each filter can be configured individually by setting type, stereo placement (all, left, right, mid and side), slope, frequency, gain and q-factor.

gEQ12 offers 16 filter types, analogue/digital design, zero delay IIR. Additionally gEQ12 provides a flat tilt filter (zero delay).

Plugin modes

The filter quality can be increased by using oversampling. This ensures "analog" filter magnitude/phase response near Nyquist frequency. On top of it gEQ12 can operate in several minimum or linear phase modes, which can lower CPU usage and makes filter phase response linear. In addition the phase of the outgoing signal can be inverted.


The main meters of gEQ12 show peak/RMS/EBU and VU loudness levels.

Perceptual Loudness Matching (AB-LM Lite)

AB-LM Lite is a perceptual A/B loudness matching algorithm to help you avoid the pitfall of 'louder is better', so you can evaluate the impact of the plugin on your incoming and outgoing audio signal at equal loudness.

When you engage AB-LM Lite, the algorithm analyzes the incoming signal and compares it to the outgoing signal via its RMS values and applies an automatic gain adjustment so you can focus on the plugin settings and what they are actually doing to your audio, without being distracted by loudness differences.

For the more advanced features please refer to AB-LM.


FIR vs IIR filter

Introduction to Filters: FIR versus IIR

Demo version versus Registered version

In demo mode (without registering) the plugin mutes audio every 90 seconds for a short period. This could be circumvented by clicking on the "TBProAudio" logo within 90 seconds.
