Hybrid is our pièce de résistance. A combination of the best qualities of clipping and limiting, rolled into the perfect all-in-one solution for mastering absolutely anything.

Clip is the algorithm you know and love from Flatline 1, completely unchanged.

Limit is a classic 90s-style brickwall limiter for ultimate transient control and distortion resistance.

Flatline 2 is your favourite mastering tool. Evolved.

Features

With envelope shaping, soft-saturation, 64x oversampling, LUFS metering for all major music platforms, channel linking, delta monitoring, DC offset & dithering, Flatline 2 is the only mastering maximizer you'll ever need.

Why Hybrid?

Hybrid represents the cutting edge of modern mastering algorithms.

By splitting a signal up into two parts - transient and steady state - then treating them individually, we are able to maximize the strengths of both clipping and classic limiting, while mitigating their disadvantages.

Every parameter has been refined in the real world, with top tier mastering engineers, to ensure it does what’s necessary to give you the punchiest, cleanest and loudest world-class masters - with no filler.

Hybrid is the ideal way to master your music.

“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.”

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!”
