Heatwave is a free one-knob saturation
plugin designed to do one thing:
Bring the Heat

Heatwave is a fast, effective, and free way to add grit and aggressiveness to almost any sound while preserving its original transients. Add sizzle to drum parts without losing the snappy attacks. Beef up a funk bass without softening the slap. Distress an acoustic guitar while preserving the intricacies of fingerstyle playing.

Heatwave employs a minimal but inspiring interface dominated by a single control to “add heat” to the sound. All the magic is hidden behind-the-scenes, so you don’t need to learn anything technical to make skillful use of the plugin. Heatwave preserves and can even exaggerate transients through a complex use of transient shaping, saturation, compression, and EQ.

Listen to the before and after examples of these sources as we crank up the heat.



This is Heatwave’s main control. Use it to increase and modify saturation, EQ, compression…everything starts with this knob. This is the first control you’ll want to go for when using Heatwave. You may not need to make any other tweaks to get a great sound.


The Input controls the level going into the Heatwave algorithm that is controlled by the Drive knob. This control can influence the overall sound of Heatwave by pushing audio harder into the algorithm — it can be used in tandem with Drive to customize the sound.


The Clip button adds a clipper on the output of the Heatwave algorithm which can keep unwieldy transients under control or be used to create a more aggressive or even distorted sound.


The Output control adjusts the level coming out of Heatwave. This control comes after the Clip button, so the character achieved with Heatwave isn’t affected. Consequently, turning the Output up can push the output level above 0dBFS, even with Clip enabled.


This button toggles Heatwave on and off. It can also be automated if you only want to use Heatwave at certain points in your track.

What Are The Pros Saying?

“I really love Heatwave on drums. Whether it’s subtle drive or more over the top saturation, it remains musical. I’ve found my new in the box go-to for warmth and character.”


Musician & Sound Designer
Naked Eyes, Wundercat, Sequential

“Heatwave is a quick path to bitey distortion that fills out in depth as you push it. Especially nice on vocals for a super clear scorch. The lower end of the knob is subtle, so don’t be afraid to push the input gain.”


Music Producer & Composer
FLAVIA, Lorelei Marcell, Olivia Reid

“I’m using Heatwave with my vintage modular synths and it quickly adds a wonderful presence and clarity to complex sounds even at low settings…it’s great! “


Sound Designer, Synthesist & Composer
Eventide, Korg & Roland

“The way Heatwave enhances beats with transients and punch is impressive. It also brings an added dimension to vocals and instruments, transitioning from a pleasant lift to a tastefully assertive edge.”


Producer, Musician & Ableton Certified Trainer
PRPL NRG, Unfollow Me., Telekinetic Walrus

“Coming from the orchestral world, I prefer plugins that are not overly detailed and complex. Heatwave delivers! Super easy to use, and it sounds fantastic!”

“Heatwave is a perfect, fast and simple solution to shape and put the heat on my kicks.”
