Honest AI feedback on your mix: what to fix first + a streaming loudness check.
Read full description
Is your song ready to release? Upload it and find out.
Rune listens to your track all the way through and gives you an honest, clear read on the mix — what works, what to fix first, and whether it's loud enough for streaming. Think of it as the experienced mix engineer you don't have in the room.
HOW IT WORKS
Upload a song, beat, demo or vocal take (MP3 or WAV). In about a minute you get:
- A verdict: Not yet, Almost, or Ship it.
- What to work on, in order — the top fix is marked "Fix this first", with practical steps for your DAW.
- Timestamped notes, so you can tap a note and hear the exact moment it's about.
- A streaming check with real measured numbers: loudness (LUFS), true peak and dynamic range, plus tempo and key — and one concrete step when something is off (for example "turn the master up about 7 dB to reach −14 LUFS").
Fix it, upload the new version, and Rune checks whether the issue is resolved. Watch the stamp climb: Not yet → Almost → Ship it.

WHAT RUNE WON'T DO
Rune won't promise you a hit and won't flatter you. It gives you an honest read on the mix and the master — and what to do next is up to you.
