Eleven Free Audio Effects For Windows

Buying Choices

Studio Units Software has announced the Studio Units plug-in collection - a collection of effects that they call a "framework for bespoke MIDI and audio processor design."


  • Combine instruments and effects in new ways.
  • Integrates with plug-ins from other manufacturers.
  • Convert between plug-in parameters, MIDI controllers and audio signals.
  • Free library of essential audio engineering tools and bizarre inventions.

There are 33 SU plug-ins, which act as building blocks that can be used to create more sophisticated sound processors.

The SU library combines these plug-ins in the following effect patches, available without the purchase of a licence:

  1. Analog Equalizer provides a ten-octave equalizer modeled on analog electronic circuits.
  2. Delay Equalizer is a feedback delay that offers panning, rectification, ping pong and filtering options.
  3. Low-pass Filter is a filter with a smoothly variable cutoff frequency.
  4. Low-pass Follower modulates filter cutoff frequency based on the envelope of the input signal.
  5. Mastering Equalizer exhibits linear phase characteristics and extreme levels of inter-band separation.
  6. Mastering Limiter provides a way of increasing perceived output levels in a neutral-sounding way.
  7. Multiband Compressor applies vacuum-tube compression to the individual octaves of a signal.
  8. Tape Compressor emulates the compression characteristics of analog tape recorders.
  9. Transient Controller allows independent control over attack, decay and sustain components of audio signals.
  10. Tube Follower modulates vacuum-tube saturation based on the input signal's envelope.
  11. Tube Vocoder combines its left and right inputs as carrier and modulator, also utilizing vacuum-tube emulation.

Pricing and Availability

The collection is currently available as a set of VST 2.4 plug-ins for Windows (XP, Vista, 7). A Mac OS X VST/AU version is also in the pipeline. It also hosts VST plug-ins.

Studio Units plug-in collection is available as a free download. The free version lets you use the 11 effects listed above.

A license is $99, and unlocks the full features of the collection. The difference between the activated version of the software and demo mode is that in demo mode, some white noise is added periodically to the output of unlocked patches. The locked patches, listed above, will not have the noise added to their output in demo mode.
