Weiss EQ1

A 1:1 code port of the EQ with no equal.

A line-by-line code port boasting 1:1 accuracy of the pioneering original hardware, known as the standard of digital mastering Eqs

Increased functionality of the original algorithms, plus 32-bit / 192 kHz operation and updated ergonomics​

Easy manual recall of Presets that sound and behave exactly like they do in the hardware

There’s a reason Weiss Engineering’s EQ1 has been at the top of the heap since its release in 1996. The EQ1’s dazzling sonic qualities combined with its flexibility as either a Minimum Phase EQ, a Linear Phase EQ, or a Dynamic EQ have made it the must-have digital mastering equalizer. The Weiss EQ1 plug-in crystallizes that legacy—in software form.

Weiss Engineering’s go-to hardware and Softube’s workflow and ergonomic advancements combine here to stunning effect. A one-for-one, line-by-line code port of the original, the EQ1 plug-in is the latest and greatest addition to Softube’s successful partnership with Weiss Engineering. EQ1 joins DS1-MK3, MM-1, and more out-of-this-world Weiss + Softube products to prove that Swiss and Swedish engineering make a stellar pair.

"In its 25 year history our EQ1 digital equalizer became the go to standard for mastering engineers all over the world. Now I am proud that Softube has managed to transfer the EQ1 into a plug-in with a sonic and ergonomic quality second to none. They even enhanced some features considerably."

Daniel Weiss President and founder of Weiss Engineering Ltd.

"Softube has done it again–The Weiss EQ1 sounds phenomenal! It sounds exactly like the real hardware unit that I've been using since the mid 90s. It's well-worth the investment and has already found a place in my mastering template. A must have for anyone who's serious about great sound!"

Doppelgänger

The EQ1 plug-in is a true line-by-line port of the original SHARC assembler code. It’s an accurate replica that functions just like the original, but with added features that take it higher.

Colossal Heights

The Weiss EQ1 is the mammoth of equalizers, but we felt compelled to go further. Softube and Weiss gave the EQ1 plug-in a higher sample rate, improved ergonomics, and increased functionality.

Picture Perfect

The EQ1 plug-in lets you easily recall Presets (or Snapshots in the hardware counterpart) manually and they'll sound and behave precisely as they do in the hardware.

"In the early days of digital, Daniel Weiss built the best sounding EQ's available with one of the most elegant interfaces I've ever experienced. He set the standard for musical processing in the digital domain… and now Softube has brought it to life in plugin form. It's great to have Daniel's beautiful EQ shapes easily accessible once again with the Minimum and Linear Phase included, and the Dynamic Mode to boot. They've included everything in the original EQ and some additions, for instance the 'tilt' feature in the analyzer, are nice innovations."

Softube & Weiss: Meeting of the Minds

Weiss has been a pioneer in digital audio equipment design since 1979. That’s when Weiss founder, Daniel Weiss, joined Willi Studer AG in Switzerland as an engineer. In 1985, Weiss struck out on his own and founded Weiss Engineering with a focus on pioneering digital audio equipment for mastering studios. The result of that endeavor is now legend.

Softube’s relationship with Weiss started in 2008 when we were first introduced to Daniel Weiss. Despite having so many guiding principles in common, it wasn’t until 2015 that we got serious about working together. Three years—and some blood, sweat, and tears—later, the Softube + Weiss DS1-MK3 plug-in was unveiled to great fanfare. And the tradition continues.

"The EQ1 is has always sounded amazingly transparent & sweet! It's great to see it finally get a 2020 makeover! The additions to the dynamic section make the EQ1-Dyn finally have controllable attack & release making it usable in many more situations! Can't wait to use this more freely now in my mastering chain!"

Warren Sokol (The Band Perry, One Republic, Imagine Dragons, Lana Del Rey, The Moody Blues, Public Enemy and Method Man)
