721 records finished with one press · mixed by our own engine · your tracks stay yours
Every function on One Button Mix is exactly that — one button. It says what it needs, spins, takes your files, works, and turns into your download. No sessions, no settings, no waiting on anyone.
SOUND LIKE THE RECORD YOU LOVE
Upload a reference. We extract its sonic blueprint — integrated loudness, EQ curve, stereo image, compression profile, tempo & key, FX trails, even the vocal tuning speed — then tune, mix and master your raw stems to twin it.
- Reference blueprint saved for reuse across songs
- Key-locked vocal tuning that leaves in-tune vocals untouched
- Loudness, tonal balance and stereo width replicated with a true-peak limiter
- A JSON log with every decision the engine made
EVERY CUSS WORD GONE. THE BEAT UNTOUCHED.
One song or a whole album. Every word is transcribed and located to the millisecond, the vocal is isolated, and each explicit word is muted vocal-only — the music never dips. You get the clean WAV and MP3, a word-by-word mute report, and the spots worth one listen.
Word-level transcription with confidence — merged tokens, self-censored words and split words all caught.
A second, independent forced alignment on the isolated vocal catches the one-word slips that happen on fast hooks.
Mix minus the high-passed vocal inside 80 ms-padded windows with 30 ms crossfades. Every window is verified: music kept, sub-bass kept.
THE PAGE EVERY RUN ENDS ON
Real figures from the run behind the demo above: three stems in, matched to the reference within a third of a dB, the lead tuned where it needed it and the harmonies left alone — in seven and a half minutes.

NO FINE PRINT. JUST FACTS.
- How is usage measured?
- Every plan comes with a month of usage, measured in credits (60 on the $49.99/month plan), and only the heavy buttons count: a clean version is 5 per song, a master 2. The light buttons — Separate, Chords, Beats, Tags, MIDI, Instrumental, Acapella — are included with any plan, and Analyze, Enhance, Convert, Atmos and Twin Master are free for everyone. While the month lasts you just see a usage bar; a run that doesn't finish never counts, and usage resets on the 1st.
- What happens when I use the month up?
- You can keep going, pay as you go. The button says GET CREDITS: one press buys 10 credits for $9.99 (bigger packs on your Account page), and the run you were about to start begins by itself when you're back. Purchased credits never expire and are spent only after the month's usage. Runs process a few at a time in the order they arrive, and every one lands in your Library whether or not you stay on the page.
- How long can a song be, and how big a file?
- Any song, reference or finished mix up to 240 minutes. Stems up to 240 minutes each and 128 per session. Up to 4 GB per file, 128 files per upload, and a Clean Version album can hold 30 tracks. We take WAV, AIFF, FLAC, MP3, M4A/AAC, OGG — or a ZIP of any of them.
- How long does a run take?
- Most buttons finish in a minute or two. A full One Button Mix is typically 4–7 min, a Twin Mix 6–10 min, a Clean Version 3–4 min per song. The button shows a live estimate the moment you upload, and you can leave — the result waits in your Library.
- What do you keep, and for how long?
- Finished work — masters, stems, reports — stays in your Library until you archive or delete it. The raw files you upload are deleted automatically after 7 days (that is also how long a failed run can be retried with the same files).
- Is there a free trial?
- Not a timed one — nothing to cancel, no card to start. Every account begins with 2 welcome credits, enough for a master of your own song, and every button open. Your first 10 credits are $4.99 (half price, once), after that 10 for $9.99, and they never expire. A plan starts the day you choose it at $49.99/month, with its full month of usage and the light buttons unlimited; cancel any time from the Account page and it runs to the end of the period paid.
The rest is on the pricing page, in Support, Terms and Privacy.
