Why master Udio?
Udio produces some of the cleanest mixes in AI music, often at a high sample rate with strong instrumental separation. That's a great starting point — but a clean mix still isn't a master. The final loudness, true-peak safety and tonal polish are exactly what mastering adds before release.
Even a clean Udio export benefits from a consistent streaming loudness, a true-peak ceiling so lossy encoding stays clean, and gentle tonal and stereo finishing so it sits next to commercial records. Quantara measures your track's integrated loudness (ITU-R BS.1770), normalises it toward your chosen platform reference, and holds true peaks under -1 dBTP — without crushing the dynamics Udio captured.
What mastering fixes in Udio output
How to master your Udio track
Export from Udio at best quality
Download the highest-quality file Udio offers (WAV preferred). A clean, high-rate input gives the best master.
Upload to Quantara Studio
Drop the file in — no signup needed to try, and mastering runs locally in your browser.
Choose your target, compare fairly
Pick a streaming target and A/B with loudness matching on, so you hear the tonal change rather than a volume jump.
Export release-ready
Export WAV 16/24-bit normalised toward the reference, true-peak-safe at -1 dBTP.
Release your Udio on the right platforms
Each platform normalises loudness differently. These guides show the right reference for your master:

Mastering doesn't affect rights. Review Udio's licensing terms for your plan before any commercial release.
