Why Udio Songs Sound Quiet (and How to Fix It)
Published · by Loopin
A Udio file that sounds quiet next to released songs is almost always just unmastered: its loudness sits several LU below streaming level and its peaks leave no room to turn it up. Measure it, clear the low end, then master it to about −14 LUFS.
Check which Udio files you actually have
At the time of writing (October 2026), Udio’s help centre says downloading audio, video and stems has been disabled since its partnership with Universal Music Group was announced on October 29, 2025. So the Udio songs most people are trying to fix are files they downloaded before then, often MP3s, sometimes WAVs.
Start from the best copy you have. If you saved both, use the WAV. If you only have an MP3, that’s fine for mastering; just don’t convert it back and forth between formats first, since every lossy re-encode takes a little more off the top end.
Measure before you guess
Drop the file into any free loudness meter and read two numbers: integrated loudness (LUFS) and true peak (dBTP). Released pop and hip-hop typically sit between −14 and −9 LUFS. If your Udio file reads something like −17 LUFS with peaks already near 0 dBTP, that explains everything: it’s quiet on average but has no headroom for a simple volume boost.
That’s why turning it up in an editor makes it clip instead of louder. You need a limiter to control the peaks so the average can rise, which is exactly what mastering does.
Clear the low end that’s eating headroom
Sub-bass energy below 30 Hz is inaudible on most systems but still takes up peak level. A high-pass at 25–30 Hz frees headroom for free. Then listen for boomy build-up around 80–150 Hz; if one bass note booms louder than the others, a 2 dB cut at that note’s frequency lets the limiter push the whole song louder without pumping.
Skip the temptation to boost bass first “for fullness”. Every extra dB of low end is a dB the limiter must remove, and the song ends up quieter-sounding for the same peak level.
Master to about −14 LUFS, not −8
Run the cleaned file through free online mastering for AI songs. The default export lands at about −14 LUFS with a −1 dBTP ceiling, which is where Spotify, Apple Music and YouTube normalise to. If the song should feel denser, try Punchy (about −11 LUFS) or Club (about −10 LUFS), and use the loudness-matched A/B to make sure the louder feel still sounds better at equal volume.
Don’t chase −8 LUFS. Streaming services turn loud tracks down to their reference level, so the extra loudness vanishes on playback and you’re left with only the squashing.
Check it against a real song
Load your master and a released song in the same style into the same player and match their loudness. If yours still sounds smaller, the gap is in the balance, usually weak kick and bass or a dull top end, not the volume. Fix that in EQ and master it again free.

Frequently asked questions
Why is my Udio song so quiet?
It's unmastered. Its average loudness sits below streaming level and its peaks leave no room for a simple volume boost. A limiter-based master to about -14 LUFS fixes it.
Can I still download songs from Udio?
At the time of writing (October 2026), Udio's help centre says audio, video and stem downloads have been disabled since the Universal Music Group partnership on October 29, 2025.
Why does my Udio song clip when I turn it up?
Its peaks are already close to 0 dBFS. Raising the volume pushes them over. Use a limiter with a -1 dBTP ceiling so the average rises while the peaks stay controlled.
What LUFS should a Udio song be?
About -14 LUFS integrated with a true peak of -1 dBTP or lower works for Spotify, Apple Music and YouTube. Denser genres can go to about -11 LUFS.
Can I master an Udio MP3?
Yes. Use the best copy you have and don't re-encode it before mastering. The master comes out as a WAV, which you can upload to a distributor.
Why does my Udio song sound quiet on Spotify but fine on my laptop?
Spotify plays everything at a similar loudness, so an unmastered track sits next to mastered ones and sounds smaller. Master to about -14 LUFS and the gap closes.
