Studio-quality mix + master, without the studio. Drop your stems — Vanta identifies each one, dials in a tailored effect chain, balances the mix and masters it loud, clean and release-ready — then shows you every call it made, so you can overrule any of them in two taps.

How it works

From raw stems to radio-ready

No plugins, no engineer, no guesswork. Three steps.

01

Drop your stems

Upload your tracked-out stems — drums, bass, vocals, synths — or a single finished mix to master.

02

Vanta listens & processes

Each stem is analysed, the instrument detected, and a bespoke effect chain applied — EQ, compression, space.

03

Mix & master, done

Stems are balanced into a cohesive mix and mastered to commercial loudness. A/B it, then download.

Why Vanta

A whole studio, decided for you

The decisions a mix engineer makes — automated, transparent, and yours to tweak.

Per-stem instrument detection

Vanta identifies what each stem is — and shows you its confidence. No tagging required.

Explainable effect chains

See exactly what was applied to every stem. Nothing hidden behind a black box.

Intelligent balance

Levels, panning and headroom set automatically for a mix that sits together.

Loud, clean masters

Commercial loudness with controlled true-peak — ready for streaming and release.

Your call, always

Mute, pan, re-gain or override any detection, then re-render free in a click.

Watch it work

Your render starts as soon as a studio slot is free — usually the moment you drop your files — with a live timer so you always know where it's up to.

Take the controls

Vanta does the work. You keep the final say.

Every call it makes is open to change — and you can hear the difference before you commit to it.

Edit any track's signal chain

Open a track's chain and switch a unit off, drag it into a new order, or add one from 25 units — FET and optical compressors, passive and channel EQs, saturation, reverb and more — then tweak its controls.

Audition before you commit

Change a setting, then hear it on that one track: a short looping cut with your changes, flipped against the current version at a matched level. Happy with it? Then re-render.

Thicken, track by track

A density control for every track: Off, Light, Medium or Heavy. It firms up the body of a thin stem while keeping its peaks in check. Medium is on by default, and any track can switch it off.

A real-time mix console

Move the faders and hear the mix change instantly — mute, solo, EQ per track, and a loudness-matched A/B against a reference track that never leaves your browser. Choose a skin for the desk, then render once to bake it in.

The chain editor, Audition and console work on your stems, so they come with any plan that mixes. The free plan is one master a month.

FAQ

Questions, answered

How long does a render take?

It varies a lot, and it depends on your project rather than on us. The two things that really move it are how many stems you upload and how long the song is — every stem is analysed, identified and processed on its own chain before anything is mixed or mastered, so a 30-part arrangement is genuinely thirty times the listening. High sample-rate sources (96 kHz and up) add a conversion pass on top.

As a rough guide: mastering one finished track is about a minute. A handful of stems is a few minutes. A big multitrack of a full-length song can run to an hour or more. You'll see a live timer the whole way, and you don't have to sit and watch it — close the tab if you like, the render keeps going and the finished track is waiting in your library.

And it's worth putting that next to the alternative. The other way to get a record mixed and mastered is booking studio time or sending your parts to an engineer — days or weeks of turnaround, revision rounds over email, and a bill per song that runs into the hundreds. Waiting an hour, for a fraction of one studio day, to get a release-ready track back from a couple of clicks is a different proposition entirely. We'd rather you waited a little and got it right.

Can I remaster if I don't like it?

Yes. Re-running the same track doesn't cost another credit — tweak your stems and re-process as many times as you need until it sounds right. You're only charged once per song.

What file formats do you accept?

WAV, FLAC, AIFF, MP3, M4A, AAC and more. Upload multiple stems at once, or a single finished track for mastering or remixing. Download your result as WAV, MP3 or FLAC.

Do I own the masters?

100%. Everything Vanta produces from your audio is yours — full commercial rights, no royalties, no strings. Release it, sell it, licence it, it's your track.

Can I cancel anytime?

Yes — every subscription is month-to-month with no lock-in or contract. Cancel in a couple of clicks from Manage plan and you keep access until the period you've paid for ends.

What's the difference between the plans?

Free is mastering only: one master a month, tracks up to 5 minutes, up to 12 files, results kept for 7 days, no card — plus one revision, so if the result isn't right you tell it what to change (too loud, too muddy, vocals buried) and it goes again. Mixing from stems, remixing a song, vocal mixing and auto-tune are paid.
Master Unlimited masters your finished stereo tracks — mastering only. Studio and Studio Unlimited unlock the full pipeline: mixing from stems, mix + master, remix-from-a-song and vocal mixing. Every card above shows exactly what's included.
