“The Arousor is a compressor plugin without equal!  Instantly exciting and instantly musical. There’s no turning back!” – Greg Wells

The Arousor is the only classic knee compressor plugin made by the creators of the Distressor, Empirical Labs. It’s been well over 20 years since Empirical Labs released its first compressor, the Distressor. From those early days on, Empirical Labs has been bombarded with requests for a great compressor plugin for those working in the box… and it had to be one with the creamy sound and ease-of-use of our own award winning hardware compressors. We are sure you will find the 20+ year wait worth it!

Features

Attack Modification

Fine tune the attack curve of the compression envelope with AtMod. The attack modification knob slows down the initial slope of the attack envelope to add just a little bit more of the transient back into the track. Whether it’s to get a little bit more snap on the snare track or more thump on the electric bass, the AtMod will let the transients through without losing your desired amount of compression.

Colorful Saturation

Add some vintage-style harmonic distortion to any track with the soft clipper. Whether you are looking for subtle or extreme amounts of total harmonic distortion, the soft clipper knob merges both of the distortion settings on the Distressor to grant the user complete control of total harmonic distortion without having to adjust the input level of the Arousor.

Advanced Detector Sidechain

Dial in exactly where you want the compression to trigger with 2 bands of sidechain EQ. This advanced detector sidechain EQ expands both of the preset detection filter circuits on the Distressor into a controllable hi-pass and parametric sidechain. Control the exact point on the frequency spectrum where you want compression to be triggered without losing any low-end.

Rivet Mode

Get maximum gain reduction with the Rivet mode along with all of the ratios you know and love from the Distressor. Modeled after the Distressor’s Nuke Ratio, Rivet provides the steepest compression ratio a compressor plugin can provide to slam room mics and more.

AROUSOR LT INCLUDED

As of 6/29/2022, all purchases of Arousor include the Arousor LT.

Testimonials

"It was immediately like greeting a friend I hadn’t seen in 10 years! Oh how I remember that sound, and the Arousor plug-in has taken it a step further. Allowing me to re-create the “SPANK” I was using with the EL-8 during the 90’s and 00’s, but with the detector sidechain EQ, giving me the flexibility to get deep into controlling how much spank and how I want to blend it.”

“I didn’t think the Distressor could be ‘improved’, but now Dave has come up with the Attack Modification and the Soft Clipping controls, not to mention the crazy sidechain options…”
John Paterno
Robbie Williams, Lustra, Robben Ford, Bonnie Raitt, etc.
“The plugin is a game changer ITB. I have for a very long time been a fan of the Distressor on snare and now I have that again. Nothing compares and on the mix I'm doing I went from feeling really good about it… to killer.”

“Wow - right off the bat - I love this thing. All the sonic characteristics of the best hardware, only more control, more color options. Handles every approach toward compression with great style, character, and when wanted, excitement. The attack modification and side chain eq are fantastic additions. Like three plug-ins in one. Plus, the x-factor…it just sounds great.”
Bob Power
A Tribe Called Quest, D'Angelo, Bobby McFerrin, etc.

Arousor Rev 3 is free for all current Arousor users. All you have to do is download the latest installer from the downloads page.

Yes and no. The Arousor is more of an evolution of the Distressor than it is an emulation because it has much more advanced features like the AtMod and the Soft Clipper.

  1. Mizraim Morales

    This plugin is totally worth it. I just put in on a acoustic guitar track and you can hear how amazing it made it sound right away. Can’t wait to experiment it on drums!!

  2. Cal Denison

    as someone who has on the hardware version of this plug-in I was excited to find out that there was a software in relation. I pulled up a song that I had been working on that I was real happy with the sound. I replaced the snare, bass guitar and master bus compressors with the Arouser. all I can say is wow! I love the sound I get out of this thing and I feel like really it gives me more of the sound that I want to believe it or not in the hardware unit. The additional features just put it over the top! I absolutely love it and it is my very favorite plug-in that I’ve ever bought and I’ve been doing this since plug-ins first came out.

  3. Robert Livingston

    This is a must have for any studio – but to be specific, if you’re making heavy music, this is non-negotiable for your drum shells. You can try and emulate the tone and gain reduction on other comps, but you’ll be left wanting. Just buy this already.

    Haven’t tried the hardware but it sounds great! Amazing on drums!
