Feb. 2018 update: F6 now includes a real-time spectrum analyzer

Surgical dynamic equalizer with 6 floating, fully-adjustable parametric filter bands, advanced EQ and compression/expansion controls per band, mid-side processing options, real-time frequency spectrum analyzer, and more.

The ultimate problem-solving EQ, F6 can be used for diverse equalization, compression, expansion and de-essing processes, whether you’re mixing or mastering, in the studio or live. Each of the six floating bands features advanced EQ and dynamic controls that let you zero in on any problem spot – and treat it only when the problem arises.

Rather than treating a frequency one time and leaving it there for the entire track, F6’s EQ settings are sensitive to the dynamics of your track. This way you can select not only by how much, but also precisely when a specific frequency will be boosted or cut, compressed or expanded.

Take vocals for example: A singer’s tone changes throughout a performance depending on their position to the microphone. An EQ setting that works well when the singer is close to the mic and singing softly will not be as effective when the singer backs up and starts belting. F6 moves in time with the singer, kicking in when the vocal level crosses a certain threshold that you’ve set – and laying off when it falls below that threshold.

With the F6, you can EQ more precisely, with filters that can be as narrow or as wide as you like, free-floating bands that can overlap, variable EQ shapes, and threshold-sensitive EQ settings. F6 is ideal for isolating specific problems on individual tracks and fixing them transparently only when they pop out. The plugin’s advanced mid-side processing capabilities give you even greater ability to carve out EQ space in a busy mix, so you can breathe more life into your mixes.

The F6 dynamic EQ also includes a feature-rich, FFT-based real-time frequency spectrum analyzer, easily accessible from the main plugin interface. Analyzer features include adjustable resolution, adjustable reaction speed, RMS vs. peak response, pre-EQ, post-EQ and sidechain options, frequency, note and amplitude display based on cursor position, and diverse L/R monitoring options.

Music is dynamic. The intensity of any piece of music constantly rises and falls. With the F6 dynamic EQ plugin, you finally have the perfect EQ tool to match this dynamic variation.

10 Tips for Effective EQ during Mastering

In this article, we’ll look at the top ten tips for applying equalization during mastering – the final stage music passes through before being released to the world.

The Glitch Mob

“F6 is like a precision scalpel; it’s unreal. If we have a distorted synth lead with one note that is too harsh, we can really get in there and control just that note. The mid-side processing is also huge for us, as so much of our work is about controlling the stereo image. To top it all off, the external sidechain allows us to trigger the F6 at the exact moment we want it to work. ”

Jason Goldstein Recording, Mixing & Mastering Engineer

Beyoncé, The Roots, Jay-Z, Michael Jackson

“The F6 is my favorite new plugin. It's like a Swiss Army knife for EQ!”

Andy Sneap Producer, Mixing & Mastering Engineer, Guitarist

Megadeth, Killswitch Engage, Arch Enemy, Judas Priest

“When I have several guitars – say four – and they’re getting a bit lumpy in the lower mids around 135–200 Hz, I’ll take the F6 and dynamically duck that area – just tickle the guitars so that the F6 is ducking them when they hit a low chug hard. I also like to use the F6 to help my cymbals come out where the snare is too dominant.”

Richard Chycki Guitarist, Engineer

Dream Theater, Aerosmith, Rush

“The F6 is a great dynamic problem solver for inconsistent, stubborn peaks and resonances. I find it very useful for taming troublesome bass note hotspots and cymbal harshness.”

Charlie Andrew Producer, Mixing Engineer, Songwriter

Alt-J, Bloc Party, Madness, Marika Hackman

“The F6 adds further flexibility to the EQ process, as I can dial in the settings so that the filters work only when needed – perfect for a vocal that sometimes sounds boomy, which a static EQ would leave sounding thin in quiet sections.”

Joe Hellow FOH Sound Engineer, Music Producer

Post Malone, Big Sean, Bryson Tiller, Tyga

“I use the F6 sidechain on our playback tracks to wrap the music around our artist, giving the audience a clean, full range dynamic mix. ”

Tomas Wolfe Production Manager, FOH Engineer

Run the Jewels, The Neighbourhood

“F6 has become my go-to plugin: it has replaced all my EQs, de-essers and multiband compressors, and it has zero latency so it goes on ALL my channels.”

Jeff Juliano Mixing Engineer

Dan + Shay, Chris Janson, Michael Ray, Hunter Hayes

“F6 is perfect for vocals and anything that needs surgical attention.”

Mike Exeter Producer, Engineer and Mixer

Black Sabbath, Judas Priest, Heaven and Hell, Cradle of Filth

“F6 maps beautifully across my C24 controller which stops me having to look at a screen and just listen – that brings me to the sound which is just great.”

Titus Woodham FOH Engineer, Audio Systems Engineer

Future, Snoop Dogg, Nas

“Dynamic EQ can shape sound in places where standard filters or multiband compressors would over-cook things; this carves them just right. ”

Ashton Parsons FOH and Monitor Engineer, Post-Production Remixer

Disturbed, Fifth Harmony, Bush, Steel Panther

“I use F6 a lot in Post-Production remixing to retain the original character of the source while controlling any whacky overtones; it’s an incredible tool. ”

Alberto Rigoni Bassist, Composer, Soloist, Producer

Vivaldi Metal Project, The Italians, Ardityon, Lady & THE BASS

“One of the most effective EQ plugins I've ever tried!”

David Cain Composer, Performer, Engineer, Producer, Filmmaker

Wertico Cain & Gray

“I love the F6. It’s an extremely useful tool for adjusting defined frequency ranges based on a dynamic threshold in a stereo space. Very powerful.”
