First time? It takes about a minute

You do not need any audio experience. There is exactly one choice to make — everything else is read from the song and set for you. Start to finish takes about a minute.

🔰 You do not even need a file yet. On the studio's first screen, ▶ Try it free with a sample track runs the whole flow on a prepared song. No sign-in needed.

#Five steps

Load a song

Open the studio and you will see a large panel that says Drop your track here. Drag a file onto it, or press Load Signal and pick one.

Accepted: WAV · FLAC · MP3 · AIFF · M4A, up to 140MB. A file downloaded straight from Suno or Udio works as-is.

Pick one of three — that is the whole setup

You will see What kind of master do you want? with three options. If you are unsure, take the first one.

🎚 Better sound — the best tone and level for this song. This is the right answer most of the time.
🛡 Lower AI-detection score — trades a little quality for it. How much it moves depends on the song.
🥁 Remix by instrument STEM — separates vocals, drums and bass first. Slower, and desktop only.

On the right you can see the track's length, size and output format. Leave the Easy | Pro switch on Easy — Pro is for turning the knobs yourself.

It reads the song — about 25 seconds

Analyzing your track appears while it reads genre and dynamics and chooses the settings. Nothing to press here.

⏳ It has not frozen. The four boxes at the top — Decode · Render · Encode · Score — are the progress. Keep the tab open and in front: the work runs on your own computer, so a hidden tab gets slower.

One button

You will see All set — just press master. plus a line like This one feels like Pop — set up to match. It differs per song.

Press ✨ Start mastering. If you want a different option, ← Change goal returns to the choice.

Listen, then download — about 30 seconds

Mastering done! appears and all four boxes reach 100%. The AI detection score is shown before and after.

Scroll down for the player. A · REF is your original and B · MASTER is the result — switch between them at the same moment in the song. Download from there when you like it.

🔊 Listen to both before you download. The master is louder, and louder always sounds better at first. The real change is in the tone.

#What you get

Output is 48 kHz · 24-bit · stereo, with loudness measured to the broadcast and streaming standard (ITU-R BS.1770-4). You can take a lossless file and an MP3 together, so the copy for your distributor and the copy you send a friend are both covered.

On the sample track there is no download — you get 🎵 Try it with your track instead. The sample is there to let you hear the difference first.

#If you get stuck

I dropped a file and nothing happened

Check the format (WAV · FLAC · MP3 · AIFF · M4A) and the size limit (140MB). Video files are not accepted.

It is taking a long time — is it stuck?

The work runs inside your own computer, so speed depends on your machine. Keep the tab in front and wait. Only when the browser cannot finish does the server take over.

I cannot see "Remix by instrument"

That one is desktop only. Phones and tablets run out of memory partway through, so it is blocked there rather than failing halfway. Open the studio on a computer.

The AI score barely moved

It varies a lot by song. The number on screen comes from our own detector and will not always agree with outside services. If the score is your goal, run it again with option 2, Lower AI-detection score.

The result sounds wrong to me

First switch between A · REF and B · MASTER at the same point in the song. If it still sounds wrong, tell us the track title and which part, and we will look at it with you.

#When you are done — put it on the chart

Add to charton the result screen puts a 30-second excerpt on this week's chart. Listeners can flip between before and after with one button, so you never have to explain what changed. Only the songs you choose go up — nothing is published otherwise.

Doing it once is faster than reading about it. You can run the whole flow on the sample without a file of your own.
