Why Your Suno Song Isn't Loud Enough on Spotify
Published · updated · by Loopin
There's a specific sequence of things to check when a Suno track sounds quiet on Spotify. Working through them in order finds the actual cause faster than guessing.
First, confirm you actually mastered it
A raw Suno export sits around −18 LUFS, well under Spotify's roughly −14 LUFS normalisation target. If you uploaded the export directly without a mastering pass, this is almost certainly the entire explanation — not a Spotify-specific issue at all.
Master to −14 LUFS integrated with a −1 dBTP ceiling before anything else on this list. Most quiet-on-Spotify complaints resolve at this step alone.
If it's already mastered, check the actual delivered file
Sometimes an unmastered version accidentally gets submitted instead of the final master — a file-naming mixup, an old version left in a distributor's upload folder. Download your live Spotify stream and check its actual loudness against what you intended to deliver.
This sounds unlikely but is one of the more common causes of a properly-mastered track sounding quiet on the actual platform.
Compare against the right thing
If you're comparing your track's Spotify volume against a different app's default output level, or against your own device's local file playback which isn't normalised the same way, you're not comparing like for like. Compare specifically against another Spotify track in the same playlist at the same in-app volume.
This apples-to-apples comparison is the only fair test, since Spotify's normalisation affects every track differently depending on how it was originally mastered.
Check whether it's loudness or clarity
If the track hits −14 LUFS but still feels quieter or smaller than tracks around it, the issue is likely tonal — a lack of presence or low-mid body — rather than loudness itself, since normalisation should have equalised raw level.
Go back and check for the mud and harshness common in AI exports; adding clarity there often closes the perceived loudness gap more than pushing the limiter harder ever will.
If everything checks out and it still sounds quiet
Spotify's normalisation setting can be toggled by individual listeners in their app settings, so a small amount of variation between listeners is expected and outside your control. If your loudness and tone both measure correctly and it still sounds off to you specifically, try a different playback device before assuming the master itself is wrong.
At that point, the most likely remaining explanation is listener-side settings, not something further to fix in the master.
Frequently asked questions
Why does my Suno song sound quiet on Spotify specifically?
Most commonly because the raw export, which sits around -18 LUFS, was uploaded without mastering. Spotify normalises to roughly -14 LUFS, and an unmastered file sounds noticeably thinner next to properly mastered tracks even after normalisation.
How do I fairly compare my Spotify track's loudness to others?
Compare it against another track in the same Spotify playlist at the same in-app volume setting, not against a different app or your own device's unnormalised local playback -- those aren't apples-to-apples comparisons.
My track hits -14 LUFS but still sounds quiet -- what's wrong?
The issue is likely tonal rather than loudness -- check for low-mid mud or a lack of presence, common in AI-generated exports. Adding clarity there often closes the perceived gap more than further limiting would.
