Kiive Audio’s Complexx is a compressor, limiter, and expander designed to tighten up any source, liven up the mix bus and add vintage warmth. Read more about Complexx below and enter our giveaway for a chance to win a free copy of the plugin.
The plugin delivers the versatility of its hardware counterpart while also delivering the convenience of modern digital features.
Complexx is currently available from the Kiive Audio product page for $89, which is 40% off the list price of $149.
Clutch and High on Fire producer Alberto De Icaza said “Complexx allows compression and expansion simultaneously with an insane amount of detail and tons of character. It is a great tool to shape tracks with heavy transients and make them feel dangerous!””

The comp can handle whatever you want to throw at it, be it individual tracks or gluing a mix bus.
In addition to offering a limiter, compressor, and expander, Complexx has side-chain filters, with the whole package offering custom dynamic control.
Let’s dig into some of the main applications for the plugin.
Complexx is right at home on your mix bus, with its soft-knee comp gluing tracks together seamlessly while retaining crisp transients.
The mix knob on the top bar also enables you to dial in parallel processing.
The plugin is also a powerhouse on the drum bus, offering anything from slamming room mics to refining your drum bus. The attack and release options offer plenty of opportunities to add punch and liveliness to your drums.
Complexx is also a natural choice for polishing up instrumental parts, adding depth and shine while retaining dynamics and detail.

Kiive Audio has not forgotten about vocals either, as the comp is right at home at delivering nuanced compression for vocals, while the expander can focus the signal to deliver clarity and upfront vocals.
Joji and Flume producer had plenty of warm words about Complexx, saying that “the plugin instantly made it to my mix bus. The compressor and expander are the perfect combination, allowing me to glue my mix together without sacrificing my transients and punch.”
Complexx offers precise control options, with 13 controls on each channel, as well as linkable stereo input and output levels. This level of control is part of the reason why the plugin is so versatile and can tackle any source.
The modern quality-of-life improvements mentioned earlier include gain and stereo linking, new width and THD options, as well as the mix knob.
