Mastering Grade Clipper
dominate your master
Flatline is the last clipper you'll ever need - bringing you the sound of pushing premium, world-class converters at a fraction of the cost.
v1.1.2 introduces M1 native compatability.
Designed with ultimate workflow in mind, it turns your mix into a world-class stream, CD or radio-ready master in a matter of seconds. Using industry-leading code, it offloads processing onto the GPU - leaving you with power to spare where it matters most (the mix!).
Instead of overwhelming you with options, Flatline instead focuses and hones in on the "secret weapon" technique of high-end mastering houses since the 2000s: The sound of clipping top-tier digital converters. This is the sound you grew up with, and it's finally within your reach.
Developed in concert with professional mastering engineers to give you only what you need, with no fluff, Flatline is a powerhouse tool: Equally at home in a project studio as it is in a high-end mastering facility.
But there's no need to take our word for it. Try it FREE for 7 days - compare it with your favourite maximizers, and we're confident you'll agree.
Thomas 'Plec' Johansson (Soilwork, Scar Symmetry)
"First rule in mastering is to do no harm, and after I've used basically every limiting/clipping piece of software and hardware directed at mastering applications available on the planet, the best sounding pieces tend to be the ones that do as little harm as possible while giving you the loudness that you're after and this is not a simple feat. Flatline has been the only piece of software that on several occasions proved to work better than my favorite $10,000 hardware box for these applications. It's simply THE best solution available today for gaining level in a clean and musical way!"
Ermin Hamidovic (Architects, Periphery, Ola Englund))
"For 15 years I’ve been working around lackluster digital limiters to create masters which don’t squash the sound of my (or my clients') mixes. Finally, with my team at SubMission Audio, we have been able to develop the ideal mastering maximizer. Flatline retains all the character of your mixes, and simply just makes them louder and more exciting. It’s the perfect mastering tool."
Simon Grove (Plini, Protest The Hero)
"Flatline is an understated monster of a clipping plugin. With simple, yet powerful controls and a useful range of analytical graphs and meters, it’s a must-have for the modern audio engineer."
Emre Ramazanoglu (Noel Gallagher, Lily Allen)
"Flatline transparently does everything I need a clipper to do, holds transients, maintains the full range of the program material and most importantly makes everything better in a beautifully musical way. This unmatched performance means Flatline is my go to clipper, whether on the mix bus, for mastering or on individual tracks."
Version 1.1.2 brings performance updates and resolves all outstanding issues with FL studio, Ableton, Cubase and Pro Tools.
