The gold-standard in mastering dynamics.

Weiss DS1-MK3. The preeminent mastering processor. The pinnacle piece of TEC Award-winning gear coveted by professional mastering engineers the world over. The crystalline sound heard on countless records is only available in software form at Softube, and only as part of our exclusive Weiss plug-in collections.

Officially endorsed by Grammy Award winner Daniel Weiss and created in collaboration with Weiss Engineering, the DS1-MK3 collection of plug-ins goes beyond modeling. With 1:1 code-ported algorithms these four premium plug-ins embody the radiantly transparent, high-quality Weiss sound—with added versatility. It’s a pro mastering engineer's dream come true.

Designed by Experts, Built on Legacy

Softube has a long history of emulating professional audio gear. For nearly two decades we've worked in close collaboration with premium brands such as Weiss Engineering, Tube-Tech, Solid State Logic, Chandler Limited®, and Trident. Our software recreations are known for accurately capturing the sound and feel of their classic hardware counterparts.

The Weiss DS1-MK3 plug-in is built on that legacy. We took the same fastidious approach we take to emulation and applied it to the process of code porting the DS1-MK3 line-by-line. This means the code of the original hardware is identical to the code found in the DS1-MK3 plug-in. It isn’t an exacting emulation. It’s the exact same product. The result is nothing less than the authentically transparent sound quality of the master of mastering processors, Weiss DS1-MK3.

Transcribed transparency

Weiss DS1-MK3 is the mastering processor every other processor wants to be. And while the others have been striving, DS1-MK3 has been perfecting the hit albums of the past 25 years. That's why it was important to us that the plug-in function 100% like the original. We undertook the painstaking task of code porting DS1-MK3 line-by-line. Meaning, you're using the exact same product with the same golden transparency.

Added adaptability

Dial in the sound that suits your session best—no matter the project, no matter the client. Updated processing sample rate resolution of 192 kHz and two new limiting modes mean the DS1-MK3 plug-in enables you to better process according to the dynamics of your specific song. In addition to DS1—the limiter that made the DS1-MK3 hardware unit a star—the software features two new brick wall limiters. Select Type 1 for highest RMS values and Type 2 when true peak is needed.

Increased insight

DS1-MK3 comes with the standard view of the original hardware plus the new addition of Waveform view. Use Waveform view to get a visible representation of how your compression levels are affecting your waveform over time. The visual feedback allows you to effortlessly track the variations in your project and optimize the sparkling sound quality for which this processor is celebrated.

Expanded efficiency: the DS1-MK3 collection of plug-ins

DS1-MK3 is the undisputed master of mastering processors. And, like every big hit, it has its spinoffs. The three additional plug-ins that make up the DS1-MK3 collection—with their code-ported DS1-MK3 components—help you more easily target specific tasks creating a fast, focused workflow. Pinpoint problem areas and achieve top-quality results quicker with MM-1 Mastering Maximizer, Deess, and Compressor/Limiter.
