Complexx $79.00

FET dynamics processor

Complexx

Shape the way your mix moves.

Complexx brings the character of legendary FET compression together with expansion and peak limiting in one plugin, giving you more ways to shape the energy of a mix. Glue your group tracks, shape the sustain of your drum recordings or push your room mics into a heavily compressed blend. With saturation, stereo width and mid/side processing alongside the dynamics, you can develop the character and response together.

Discover Complexx

Classic dynamics with room to experiment.

Complexx gives you control over your strongest transients and the quieter audio around them. Use compression to shape the overall response, expansion to shape the sustain and quieter details, and the Peak Limiter to bring the strongest peaks under control. Each brings a different decision into the same plugin, with the range to shape individual recordings, drum groups and your mix bus.

Complexx compressor Attack, Release, Threshold and Ratio controls plus native Mix Complexx compressor Attack, Release, Threshold and Ratio controls plus native Mix

Choose how your compression responds.

Switch between three attack settings to move from a fast response to one that lets more of your initial transient through, then shape the recovery with the Release control. Complexx gives you the timing to experiment with firm level control, sustained room mics and the movement of a whole drum group. Its Mix control brings parallel compression into the same plugin, so a heavily compressed setting can become part of the balance rather than the whole result.

Complexx expander Release, Threshold, Range, Attack and EXP/OFF/GATE controls

Shape the sustain as well as the impact.

Expansion lets you reduce quieter audio below the threshold, giving you another way to shape sustain and the space around a recording. In Gate mode, you can take that further, with Range and timing controls to shape how it opens and closes. Try it when a drum recording feels too spread out, or when you want a more pronounced change in its sustain. It gives Complexx another way to influence the rhythm before compression.

Give the strongest peaks their own control.

Compression and peak limiting bring different responses to a mix, and Complexx gives you both in the same plugin. Use the Peak Limiter to work on the strongest peaks alongside the compressor’s broader dynamic movement. You can shape the energy of a drum group while giving those occasional stronger transients their own treatment.

Complexx Input plus 1:1 compressor ratio and Mono, Stereo and Mid/Side controls Complexx Input plus 1:1 compressor ratio and Mono, Stereo and Mid/Side controls

Hear its character without compression.

Choose the 1:1 ratio and drive the input to explore Complexx’s saturation without compressor gain reduction. It gives you a different reason to reach for the plugin when the dynamics already sit where you want them. Linked input and output controls help compensate for gain changes as you experiment, while dual mono, stereo and mid/side modes give you different ways to work across a stereo recording.

A few things to know

Frequently asked questions.

Is Complexx only a compressor?

It also includes an expander, gate and Peak Limiter. You can explore saturation without compressor gain reduction by choosing the 1:1 ratio.

Where does expansion happen?

The expander and gate operate before compression. Their threshold, range and timing controls let you adjust how quieter audio is reduced.

Does Complexx include a limiter?

Yes. Its Peak Limiter gives you peak control alongside the compressor and expander.

Can I use Complexx for parallel compression?

Yes. Its built-in Mix control blends compressed and unprocessed audio inside the plugin.

Does the sidechain filter remove bass from the audio?

No. It filters the signal used by the compressor’s detector, letting you reduce the low end’s influence on compression without applying that high-pass filter to the audio itself.

Can I process the center and sides separately?

Yes. Complexx includes mid/side processing alongside dual mono and linked stereo modes, plus a stereo Width control.

Can I try the complete plugin?

Yes. The trial is fully functional for 14 days, with no credit card required.

Which formats are supported?

VST3 and AAX on Mac and Windows, plus AU on Mac. Native Apple Silicon support is included. See the current system requirements for your setup.
