Why Does My Suno Song Sound Quiet on Spotify? (And How to Fix It)
Short answer: Your Suno song sounds quiet on Spotify because raw Suno exports typically measure around -18 to -22 LUFS, far below the level commercial masters are built at. Spotify normalizes playback toward roughly -14 LUFS, but turning an unmastered track up doesn't make it sound big — it exposes thin peaks, loose bass, and a narrow image. The fix is a proper mastering chain (EQ → compression → limiting → loudness target), not a volume knob.
Why raw Suno exports come out quiet
This isn't a bug. Generative models render with conservative headroom — quiet output avoids clipping across wildly different genres and prompts. The result is a file that's safe but nowhere near release level: low integrated loudness, uneven dynamics, and peaks that were never gain-staged for streaming playback.
That's also why the problem doesn't go away when you regenerate or use Suno's Remaster button — those change the generation, not the exported file's loudness. (More on that in What Does Remaster Do in Suno?.)
What each platform actually does to your track
All the big platforms use loudness normalization — they measure your song and adjust playback toward a house target:
| Platform | Playback target (approx.) | What happens to a -20 LUFS Suno export |
|---|---|---|
| Spotify | ~-14 LUFS | Turned up ~6 dB — thin peaks and loose low end get exposed |
| Apple Music | ~-16 LUFS (Sound Check) | Turned up ~4 dB — same problem, slightly gentler |
| YouTube | ~-14 LUFS | Turned up — and lossy encoding makes brittle highs worse |
(These targets shift over time — treat them as ballpark, and verify on each platform's official docs before relying on exact numbers.)
The key insight: normalization changes playback volume, not sound. A commercial master at -14 LUFS and your export turned up to -14 LUFS play at the same meter level — but the master sounds dense, wide, and punchy while the raw export sounds thin. Loudness normalization equalizes volume, not perceived power.
How to check your track's LUFS (free, 2 minutes)
Before fixing anything, measure:
- In a DAW: load a LUFS meter (Youlean Loudness Meter free version works in any DAW) and play the whole track. Read the integrated number.
- No DAW: upload the file to a free online LUFS checker, or drop it into our studio — the analysis stage shows loudness before you commit to anything.
If your integrated LUFS is in the -17 to -22 range, you've found the problem. That's normal for a raw AI export.
Turning it up ≠ mastering it
When a track was never mixed for extra gain, raising the volume just exposes what was hiding:
- Peaks get harsh and brittle instead of dense.
- The low end feels loose instead of tight.
- The stereo image stays narrow while commercial tracks feel wide and full.
That's the "thin and quiet" feeling. It isn't a quality ceiling in the AI model — the track just hasn't been through a gain-staged chain. (If your low end is the biggest offender, start with fixing muddy bass in Suno tracks.)
The fix: four steps, in this order
Real loudness comes from sequence, not force. Each step makes room for the next:
- EQ — clean the tone first. Tame boxy low-mids (Suno tracks pile up around 200–400 Hz), control harsh top end, roll off sub rumble below ~30 Hz.
- Compression — even out the dynamics so loud and quiet moments sit closer together, gently.
- Limiting — catch the remaining peaks transparently so the overall level can come up without distortion. Use a true-peak limiter — plain sample-peak limiting lets inter-sample peaks clip after encoding (why that matters).
- Loudness target — land the finished master around -14 LUFS integrated with true peaks below -1 dBTP.
Do these out of order and you fight yourself: limit before you EQ and you're squashing problems you could have removed; chase loudness before compression and the peaks eat all your headroom.
Common mistakes that keep Suno tracks quiet (or ruin them)
- Just normalizing the WAV to 0 dB. Peak normalization raises the tallest spike, not perceived loudness — the track still reads -19 LUFS.
- Slamming a limiter 8 dB into gain reduction. You'll hit -14 LUFS but it will pump and crackle. Loudness you can't hear as distortion comes from the three steps before the limiter.
- Exporting MP3, mastering, then exporting MP3 again. Every lossy pass bakes in artifacts. Master from the highest-quality export Suno gives you, and convert to MP3 once, at the very end.
- Mastering to -9 LUFS "to be safe." Streaming turns it back down and you paid for it in crushed dynamics. Around -14 is the sweet spot for AI tracks headed to streaming — see LUFS targets for every platform.
What to expect after mastering
A properly mastered Suno track at ~-14 LUFS doesn't just play louder before normalization — it survives normalization. Density from compression, controlled peaks, and a clean tonal balance are what make a track feel "commercial" at equal volume. A/B your raw export against a mastered version at matched volume and the difference is immediately obvious in the low-end grip and the top-end smoothness.
If you'd rather not build the chain by hand, Anti-AI Master runs this exact EQ → compression → limiting → loudness sequence in your browser and exports a distribution-ready 24-bit master in about ten seconds. Preview is free, no account — an easy way to hear what your track sounds like at streaming loudness before you upload.

FAQ
Why is my Suno song so much quieter than other songs on Spotify? Raw Suno exports typically sit around -18 to -22 LUFS while commercial masters are engineered for streaming playback. Spotify normalizes volume, but an unmastered track turned up still sounds thin because it lacks the density, peak control, and tonal balance mastering provides.
Does Spotify make my song louder automatically? Spotify adjusts playback toward roughly -14 LUFS, so quiet tracks are turned up. But normalization only changes volume — it can't add the punch, width, or density of a mastered track.
What LUFS should a Suno song be for Spotify? Around -14 LUFS integrated with true peaks below -1 dBTP works well for most AI-generated tracks headed to streaming. Louder than ~-11 and normalization turns you down while the crushed dynamics remain.
Can I just turn up the volume instead of mastering? Turning up raises peaks until they clip; peak-normalizing barely changes perceived loudness. Mastering raises perceived loudness while keeping peaks controlled — that's the difference you hear next to commercial tracks.
Does Suno's Remaster button fix the loudness? No — Remaster generates a refined variation of the song inside Suno; the export is still a raw render at low loudness. Mastering happens on the exported file. (Details here.)
