Artist reviews
What producers say.
Flatline 2 is outstanding - Hybrid mode is super impressive, combining the best of clipping and limiting to create masters that are clean, punchy, and crystal clear. With precise envelope control, lookahead, and LUFS metering, it's an essential tool for both mastering and track clipping/limiting.
Flatline has been my go-to clipping plugin ever since its first iteration. With its ease of use and great sounding, well thought-out soft clipping curve, it's no wonder it ended up on several projects I've mastered in the past few years. With Flatline 2, the team at SubMission Audio has taken everything even further with a beautiful new UI and, most importantly, the addition of the Hybrid mode, which turned this plugin into a versatile powerhouse and a must-have in any mastering engineer's tool box.
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!
