Red EQ – Free Coloring Equalizer VST Plugin Released By Acustica Audio


Red EQ by Acustica Audio.Acustica Audio has announced the release of Red EQ, a freeware 3-band coloring equalizer VST plugin for Windows and Mac based on Acqua technology.

The Red Eq equalizer provides three fixed bands at 80Hz, 1.8kHz and 8kHz, and though the EQ may look limited compared to a parametric, it actually sounds nicely musical and the frequencies have been chosen with care.

The equalizer features three fixed bands with up to 6 dB boost/cut per band. The low and high bands act as shelving EQs, while the mid band has a standard bell response. The interface also features input and output gain controls, along with a power button which can bypass the EQ section.

The input meter located on the right side of the interface is useful for preventing unwanted distortion of the audio signal on the input. If the red warning lamp lights up, you should reduce the input gain in order to prevent clipping of the signal.

If you like the Acqua technology approach to equalizers, you should definitely also take a look at ARQ High EQ by CDSoundMaster. If works great for enhancing the higher frequency ranges of audio signals, adding just the right amount of sparkle and air on top. For a nice selection to more traditional EQ plugins, take a look at our list of freeware parametric equalizers. The one which I currently use the most is SonEQ by Sonimus. Another brilliant pick is obviously SlickEQ by VOS and TDR.

To grab your free copy of Red EQ, add it to your shopping cart on the product page linked below and proceed to free checkout. You’ll need to create a free Acustica Audio user account, after which the download link will appear in your browser Window.

Red EQ is available for free download via Acustica Audio (53.8 MB download size, ZIP archive, 32-bit & 64-bit VST/AU plugin format for Windows & Mac).

    Generous offer, Thanks!

    I also regularly use some of the demo Acqua VSTs by CDSoundmaster, especially the R2R Revox Tape Program, the Neve Channel EQ and the Nice EQ Demo – limited functionality – but very useful plugins. Too bad they are so CPU hungry and introduce so much latency – otherwise I would say Acqua / Nebula is the way to go.

  2. I have always found that the CdSoundmaster and nebula plugins sound amazing. As stated above they can cause latency but an effective work around this problem is too bounce the track with the effect then import it back into your session.

      Yeah, while this is possible, it destroys the “intuitiveness” of mixing. You want to tweek your settings on the go, apply little changes in the context of the whole song.

      Today, many “bedroomproducers” don’t seperate the processes of recording/arranging/composing and mixing – it’s all one big process. Latency and cpu-hunger becomes a real problem here, especially in in-the-box productions with virtual instrruments that need to be played and processed in realtime.

  3. I was excited to try this but (just like every other Acoustica plugin) there is no 64bit AU and 32 Lives does not let me use it properly.

  4. At last it looks like vst users have themselves a Joe Meek EQ plugin.

    This is clearly a TFPro P3 and its what became of the old ‘British’ Meeks after Ted Fletcher sold the Meek name and set up TFPro.
