Thomas Johansson testimonial image
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."
