In the jungle of third party Audio Unit plugins, ‘free’, as in zero-cost, doesn’t necessarily mean low quality. Nor does a less funky GUI. Here’s a list of free Audio Unit plugins worth taking for a spin in Logic Pro, or any DAW that supports Audio Units. There’s lots to choose from, happy tweaking!

Flux

Flux offers two free plugins (submitting your email address required):

  • Bittersweet II – a transient designer, offering separate shaping of the Mid and Side signal. 32-bit.
  • Stereotool – features control of input gain and individual pan for left and right channels. A phase inverter, global stereo pan and stereo width settings, vector scope display, PPM meters for both inputs and outputs, and a phase correlation meter are included. 32-bit.

Blue Cat Audio

Blue Cat Audio, famous for their plugins that have controller output offers a free plugin bundle, available here. The bundle, updated to version II on March 28th 2012, includes:

  • Chorus
  • Flanger
  • FreqAnalyst (Analyzer)
  • Gain Suite
  • Phaser
  • Triple EQ

Most effects are available in Logic Pro , but for a different color, be sure to check out these out. Both 32 and 64-bit.

Brainworx

Brainworx offers two very useful plugins:

  • bx_solo – discussed in the ‘Solo The Sides’ series part one, two and three. Requires submitting your email address. 32-bit.
  • bx_cleansweep – Lowpass and Highpass filtering with ‘Anti Crush Technology’. Requires submitting your email address. 32-bit.

Voxengo

Voxengo offers a series of free plugins (both 32 and 64-bit):

  • OldSkoolVerb – released early March 2012. This plug-in implements a “classic” stereo reverb algorithm and produces a very “clear spatial image that blends well with the mix”.
  • Tube Amp – applies asymmetric tube triode overdrive.
  • SPAN – a real-time “fast Fourier transform” audio spectrum analyzer plug-in.
  • Overtone GEQ – a 7-band harmonic (overtone) graphic equalizer that supports mid/side channel processing. Overtone GEQ applies harmonic enhancement processing.
  • Sound Delay – Sound Delay features internal mid/side encoding and decoding, and allows you to delay mid and side channels independently.
  • Stereo Touch – this plug-in takes a mono input signal and generates a stereo output signal.
  • Marvel GEQ – Marvel GEQ is a linear-phase 16-band graphic equalizer. It supports mid/side channel processing.
  • MSED – use this to extract mid-side channels, swap stereo channels, or switch polarity of a signal.

Camel Audio

Camel Audio has two free plugins:

Izotope

Izotope offers one free plugin: Vinyl. It will make audio sound as if it was a record being played on a record player. That may sound lame in 2011, but the bursts of noise it creates are random (put it on an empty audio region just to get the effect). Use it as a source for sidechaining for a creative effect, or combine it with Bluecat’s plugins that offer controller output. Requires registering with Izotope. 32-bit.

    Thanx for the round up :) I didn’t know about the Voxengo’s. Will give them a try.
    I would have add all the plugs from Togu Audio Line : impressive quality for the (absence of) price…

      GboX,

      Thanks man, I did not know about these!

      Will try them out and include them in the next 20.

      Cheers

    good list (I would add Togu as well). nice tip on Vinyl, will try that for sure (maybe through a vocoder). I use vinyl mixed in with drum samples to give a little grit. if you tweak it you can get some interesting stuff that doesn’t sound like you’re trying to sound like vinyl.

      Rabbitears,
      I have to try that one out, thanks!

    Vinyl was my gateway drug to iZotope’s plugins. I ended up buying most of their offerings. I use Ozone on pretty much everything.

    Hey Danski,

    Thanks for the heads up re the plug-ins!  Quick question: just downloaded some plug-ins from flux that you recommended, but now I can’t locate them on my computer.  I can only seem to locate the download packages.  I’ve downloaded the plug-ins twice now, but still no luck.  I’ve searched my hard drive folder (I have a mac) and also went to user>library>audio>plugins>components and still no luck.  Any ideas?  Thanks.

      Hi Jschmidtiii,

      Look in the system wide version of the folder you’re looking in, i.e. Macintosh HD/Library/Audio/Plugins/Components. Let me know how that works out! Cheers.
