// WORKFLOW

Same three steps a senior engineer would take. Executed in 3:42.

No black-box magic — every master is traceable, reversible, and tuned to a reference you actually love.

  1. 01

    Upload stems

    Drag-and-drop your session — WAV, FLAC, AIFF, or stems straight from Ableton, Logic Pro, FL Studio, or Pro Tools. The Stem-Aware engine parses vocals, bass, drums, and music independently before limiting.

// Reference-Match AI v3

An engineer that has heard everything you've heard — and 18 million tracks you haven't.

Reference-Match AI v3 ingests your rough bounce, learns its sonic character against any reference you drop in, and returns a release-ready master with stem-level decisions you can actually defend in a label A&R meeting. Trained on 18 million professionally mastered tracks spanning 41 genres — from Detroit techno to K-pop to bedroom indie folk — it doesn't guess what a master should sound like. It pattern-matches against the catalog your genre has already approved.

The Stem-Aware engine: re-balances your master before it limits.

Other AI masters push a flat stereo bus through a limiter and call it done. Gemix separates your stems first — vocals, bass, drums, music bed — and re-balances their levels against your reference curve before loudness processing. The result is a master that sits on a playlist next to your reference, not one that just shares its loudness.

  • Vocals ducked 1.2 dB under heavy low-end hits
  • Bass tightened 40–120 Hz before limiting
  • Drums re-energized at 2.8 kHz presence band
  • Music bed parked safely behind the lead

Adaptive EQ + psychoacoustic loudness

11 granted USPTO patents cover the EQ curve logic and our psychoacoustic loudness model — meaning we're not just turning a volume knob, we're modeling how human hearing actually perceives a mastered track across genre, playback system, and listening environment.

// Built by people who have shipped records like yours

Engineered by Grammy-level ears, not marketing interns.

A 38-person team anchored by 9 PhDs in digital signal processing and four former senior engineers from Ableton, Native Instruments, and iZotope. Endorsed by multi-Grammy engineers Tchad Blake and Greg Kurstin, plus six other working mixers with walls of credits behind them. The proof isn't a logo on a slide — it's 2.3 million tracks shipped worldwide.

"I've A&B'd it against my own passes on rock and latin records. It gets the bones right. I keep it open during mixing as a second opinion."

Tchad Blake Multi-Grammy engineer · Pearl Jam, Tom Waits, Latin Grammys

"The stem-aware rebalance is the bit I was skeptical about. Then I tried it on a pop recall. It made choices I would have made — in forty seconds."

Greg Kurstin Multi-Grammy producer · Adele, Beck, Foo Fighters

"My external mastering chain pulls maybe 6 dB of dynamic range correction a session. Gemix is doing that before I even open the chain."

Six additional multi-Grammy engineers Mix & mastering credits across pop, hip-hop, electronic, indie

"Eleven patents on adaptive EQ and psychoacoustic loudness is not a slide-deck claim — it's the kind of R&D the big three plugin houses used to keep in-house."

// Drops into your session

If you produce in it, Gemix renders out of it.

No bounce-out, re-import gymnastics. Render a master directly from the DAW you already wrote the record in, then push it straight to the platforms that pay you. VST3, AU, AAX, and a headless render API for the people running session automation.
