Stem-aware AI mastering — hear the full master free first
6 followers
OneMaster masters music in your browser. Upload a finished mix, or a beat and a vocal as separate files: each part is treated on its own, then summed and mastered into a 24-bit WAV. AI Mixing blends 2–8 stems into one mix, and OneMaster Studio is a multitrack DAW with a piano roll. Hear every master in full before you pay; one song credit downloads it. First song $4.90, then $9.90, no subscription, 3 re-masters included. Free BPM & key finder and audio converter.

> Hey Product Hunt 👋

>I'm Mil — independent musician. I built OneMaster because I was tired of two bad options for indie artists:
>
>*1)* Pay a studio engineer $200-500 and wait 3 days
> *2)* Use a free AI tool and get a squashed, lifeless master with no personality
>
>Existing AI mastering tools take your full mix as a single file and run a generic chain. They can't tell vocals from drums — so they over-compress the vocal trying to control the kick, and you end up with that classic "pumped" sound that ruins the track.
>
>*OneMaster works differently.* You upload beat and vocals as separate channels. Each gets its own DSP treatment — de-essing + presence boost on vocals, HPF + low-mono prep + glue comp on beats — and THEN they're summed and run through a 3-pass loudness chain tuned for Spotify/Apple/Tidal delivery specs. The result sounds like it actually went through a mastering studio, because the chain is the same one.

>A few things I'm proud of:
>
>• *10 seconds* from upload to delivery
> • *Hear the whole master free*, start to finish, before you pay — zero card
> • *3 re-masters included* on every paid master — try another genre preset or a reference track, no extra credits
> • *Transparent pricing*: per song, no subscription, credits never expire. First song $4.90, then $9.90; 3 songs $24.90, 15 songs $89.90

>This is the tool I wished existed when I was uploading my first song. Now it does.

>Update, Oct 2026: AI Mixing (2–8 stems) and OneMaster Studio, a browser DAW, are live too. Try it free at *onemaster.ai* — would love to hear what you think. Especially open to feedback from other producers on the chain quality and the stem-aware approach 🙏
