Auto eq stereo tools
ThirtyOne MK2 provides three different “Auto EQ” algorithms: Average, Median and Lucky, the first two are based on some mathematical models while the third one is a lucky mistake and we decided to keep it because it sounded good □ The equalizer has a very special feature called the “Auto EQ”, when enabled the output of the spectrum analyzer is used to tune the gain for each of the EQ band allowing the equalizer to automatic set itself so that the maximum harmonic balance is achieved. Each of the sliders drives a standard 1/3 octave second order filter and can be adjusted from -15 to +15 dB, you can also change the value for each band typing in the box below each slider. Right below the spectrum analyzer we have put the 31 sliders that will let you shape the output and fix any particular resonance. We also added a maximum peak hold LED for each frequency band that can be enabled or disabled that the original unit did not have. We put a great care in recreating the smooth lighting of LEDs driven by a smoothly increasing current flow, each column of twelve LEDs comes after a 20dB/octave filter (like the original hardware unit) and it’s response speed is selectable between 0.25, 1 or 4 seconds allowing you to see both fast peaks and average frequency level.Įach of the LED of the bar can have a value of 1, 2 or 3 dBs (like in the original hardware unit) and we also added 6dB/LED option, when changing the resolution the scale on the left of the LED display updates accordingly.
The equalizer is also inspired by analog units allowing ThirtyOne to recreate that master chain feeling that you are used to. This pair of tools is very common in every rack of any live mixer as the final tool in the master bus, for this reason we decided to recreate the behaviour and specific time response of a very common Italian analog spectrum analyzer. ThirtyOne MK2 is a plugin that includes a spectrum analyzer and a graphic equalizer, both have the standard 31 one third octave bands.
