How it works
Four steps between your mix and a ready-to-release master.
Master the same mix twice and you get the same result. No random tweaks, no luck. What you preview is exactly what you download.
- 01
Upload your mix
Drop a WAV, AIFF, FLAC or MP3. We'll validate the file and flag anything we spot before we start.
~10 seconds - 02
We analyse and plan
Loudness, spectral balance, stereo width and transients get measured and a mastering plan is generated for each preset.
~30 seconds - 03
Compare four masters
Listen to Balanced, Club, Club Hot and Warm on the same part of your track, level-matched (same volume, so it's a fair comparison) or at real-world loudness.
~1 minute - 04
Export and ship
Pick a preset, pay, and download a verified 24-bit WAV, 16-bit WAV and 320 kbps MP3 with a full mastering report.

Creative presets
Multiple masters, one mix.
Each preset uses the same measurements and the same safety limits. What changes is the creative intent: tone, density and level balance. Compare them level-matched to hear character, or at real loudness to hear how they’ll land on streaming.

Producer-built
Automated speed,a producer’s ear.
These presets weren’t trained on a pile of someone else’s masters. They were tuned by Aden Forté, a producer, mixer and former Head of A&R with twenty years of club and chart records, around how a finished record should feel: where the low end sits, when loud turns harsh, how much punch survives the limiter.
So you get the part of mastering that should be fast and affordable, with the judgement that shouldn’t be automated already built in.

FAQ
Everything you probably want to ask before you upload.
Still have questions? Our humans answer within a business day. Hit the contact page with your track details.
What files do you accept?+
WAV, AIFF, FLAC and MP3 stereo mixes up to 500 MB and 15 minutes. MP3s are accepted with a lossy-source warning. A WAV or AIFF will always sound better.
How loud will my master be?+
Each preset has a loudness goal — Club Hot is the loudest — but the final level adapts to your mix. Dense, club-ready mixes reach the full preset level; very dynamic mixes are delivered at the loudest level that stays clean, usually a little quieter, instead of being crushed to hit a number. Streaming platforms normalize playback to around -14 LUFS anyway, so this costs nothing on Spotify or Apple Music and your punch survives. When we adjust the level, the preview screen and report tell you exactly what we did and why.
What if my mix isn't ready?+
Our readiness check flags clipping, severe limiting, bass-width problems and brightness issues before you pay. If your source isn't suitable, we'll point you to mixing, AI finishing or full production instead.
Can I change my mind after paying?+
You can compare all preset previews before paying. Once you choose and pay for a final master, that selected preset is the one we deliver.
Do you use my audio to train AI?+
No. Uploaded audio is never used to train models unless you explicitly opt in. Free previews are deleted after 72 hours; paid one-off masters have a 30-day redownload window.
What if the master doesn't pass verification?+
We never mark a master finished until it passes our checks: the right loudness, no clipping, the full length, and a clean file that opens properly. If we can't deliver one that passes, you get a refund or credit, and you never receive the broken file.
Do you offer human mastering or album modes?+
Album and reference mastering are coming soon. For now we offer fast, automated single-track mastering; anything more hands-on goes into our mix-and-master or full production services.
How long until I have my files?+
Most previews are ready inside 60 seconds; final masters inside five minutes for common track lengths. Longer tracks or unusual sample rates may take longer and will always show a live progress state.
Is this AI mastering?+
Call it what you like: automated or AI-assisted mastering. The difference is what comes out. A lot of AI mastering tools give you speed and a flat, over-limited master; ours is tuned by engineers who actually play these tracks out, so it's fast and it still sounds like a finished record.
Do I need a subscription or an account to download?+
No subscription, and no monthly plan to unlock your file. Preview for free, and when you find the master you want, you pay once and it's yours: WAV, MP3 and the full report.
Is automated mastering actually any good for $10?+
That's the whole point: affordable without the cheap sound. At $10 it's a fraction of a studio session, but the masters are club-tested and release-ready, not just turned up loud.
