Prompt to Mastering
Type what you want in plain language; an AI mastering engineer renders a new revision and tells you what changed. How it works, and prompts that land.
#The idea
The prompt bar sits at the top of the mastering workspace, and it is the shortest route to the sound in your head. Say what you want in your own words and your current AI engineer takes it from there. It listens for intent, not keywords, so "make it feel like a late-night drive" is a perfectly good instruction.
Every prompt goes deeper than the buttons could on their own. The engineer works from what it knows about your track, your genre and the conversation so far, renders a new 30-second preview, and comes back with a short note on what it changed. The Revision Suite on the left is not a fixed list either: it adapts to each revision, reflecting the direction the engineer took so you can nudge from there.
#How to send a prompt
- Make sure Prompt is selectedThe switch at the very top toggles between Prompt and Reference. Prompt is the default.
- Type between 5 and 500 charactersPlain language, any language. The engineer answers in the language you wrote in.
- Press Enter or click Apply PromptShift+Enter adds a line break if you like paragraphs. A new row appears in the Mastering A/B list immediately and fills in when the render is done.
- Read the reply, then listenThe engineer summarises what it changed in one or two lines. The new revision is auto-selected, so pressing play compares it at the same spot in the song.
#What a good prompt looks like
Describe the result, not the process. The engineer knows its tools better than a list of gear names would tell it. Complaints work great too: "too harsh", "muddy low end", "clipping in the chorus" all map to specific fixes.
| You want | Try | What you hear |
|---|---|---|
| A louder, modern master | "Make it louder but smooth, keep vocals clear and reduce harshness" | More level, vocals up front, the top end tamed |
| Less aggression | "Less compression, more open dynamics, slightly wider" | Room to breathe, a little wider, less push |
| Vintage flavour | "Vinyl glow with a soft halo, clean and intimate" | Warmth, tape softness, a touch of space |
| Fix a problem | "Remove harshness in the mix" or "cleaner low end" | Harshness gone, low end cleaned up |
| Streaming safe | "Optimize it for Spotify" | Competitive level with headroom to spare |
| Mono venue | "Optimize for a club that has MONO speakers only" | Everything holds up when the sides collapse |
#It remembers the conversation
Each project keeps the conversation going with your engineer, so follow-ups work: "a bit warmer" after "make it louder" builds on the previous settings instead of starting over. Say "undo that" and the engineer reverts its last change. Say "reset" and everything goes back to Balanced with Intensity at 70.
#Stem-level requests
This one surprises people. While you work, the 30-second preview is quietly split into vocals, drums, bass and other in the background. Once that is ready, the engineer can re-balance stems when you ask explicitly:
- "Bring the vocals forward and turn the drums down 2 dB"
- "Remove the vocals and keep it instrumental"
- "Lower the guitars and synths 3 dB so the vocals sit on top"
Amounts are honoured when you give them. Without a number, "slightly" means about 3 dB, a plain "turn down" means 6 dB, and a plain "turn up" means 3 dB. Tone words ("soften the vocals") are still treated as tone, not stem volume. If you ask before the split is ready, the engineer will say so and suggest trying again in a moment. For serious stem work, Stem Split Studio is the right tool.
#Voice Mode
The microphone button opens Voice Mode. Speak your prompt, press Enter, and the engineer answers out loud in its own voice while the revision renders. It is exactly the same prompt underneath, and it has its own page.
#Things worth knowing
- Every prompt is a new revision. Nothing is overwritten. If the new one is worse, click the previous row in Mastering A/B and carry on from there.
- Replies are short on purpose. Under 200 characters, no jargon, no lists. If you want to see the numbers, look at the A/B row or the Revision Suite.
- Prompts move Intensity too. Complaints about harshness or clipping ease it off; asking for more push turns it up.
- A mastering seed in a prompt is a starting point. Paste a seed and the engineer applies that recipe first, then your words on top.
Added warmth, kept dynamics open, made the stereo image wide, and kept the bass mono-safe. Let me know if you want more vintage flavor or tweaks!
Default engineer, replying to "Warm like 60s jazz, keep the dynamics, wide stereo but mono-safe bass"
Can I write in Turkish, Spanish, Japanese...?
Yes. The engineer reads any language and replies in the same one.
Why did it not do what I asked?
We work on this every day, and the engineer keeps getting better at reading prompts. If a result surprises you, describe how it should sound rather than what to do, add a word about how much, and A/B the new revision against the previous one. A follow-up like "more of that" or "less bright" usually lands it.
Is there a limit on prompts?
Each prompt is a revision, so the per-project revision limit applies: 10 on free accounts, 20 on Unlimited, no limit on Unlimited Plus.
Does the engineer hear the track?
It works from a detailed analysis of your track, your prompt and the conversation so far, and it gets sharper with every follow-up. Your ears make the final call, which is exactly what the A/B list is for.
