EQ30 Graphical Equalizer 32-bit VST Plugin By discoDSP Is Now FREE


discoDSP has announced that the EQ30 graphical equalizer in 32-bit VST plugin format for compatible digital audio workstations on Windows is now freeware.

EQ30 is a software graphical EQ modeled after the Alesis M-EQ 230 hardware unit. The plugin comes with the same feature set as its hardware counterpart, which is a dual 1/3 octave 30-band equalizer. The boost/cut range is ±12 dB and the bands cover the frequency range between 20 Hz and 20 kHz. EQ30 also features input and output gain controls, along with the solo buttons for the L and R audio channels. This is a very old plugin which was first released all the way back in 2003. I can’t find any information about its original price so please leave a comment below if you know how much it used to cost before becoming freeware.

Unlike parametric equalizers which are useful for pinpointing specific frequencies in a sound, graphical EQs are best suited for gently fine-tuning the entire mix. They are also used in venues to adjust the frequency response of the audio system so that it sounds as good as possible in a particular room. In the software realm, there aren’t many advantages when using a graphical equalizer instead of a parametric one, but some users might find them more convenient for certain tasks.

The fact is that there aren’t too many freeware graphical equalizers around, so EQ30 is well worth checking out if you’re interested in adding this type of plugin to your arsenal. The downside is that EQ30 is only compatible with 32-bit VST plugin hosts for Windows. You can download it completely free of charge from the developer’s website, though, no registration required. The download pack contains a user manual which includes some rather handy EQ tips for beginners.

EQ30 is available for free download via discoDSP (125 KB download size, RAR archive, 32-bit VST plugin format for Windows).

  1. The 32-bit limitation is a real bummer. There’s a serious lack of good, free graphical EQ plugins, especially ones with more than 7 to 10 bands. A 64-bit version would have made my day.

  2. Brute, just get jbridge for 14 bucks, you get versions for both Mac and PC, it is super handy for those times you need to be able to use 32-bit plugins in a 64bit DAW (and vice versa)
