How to Master a Suno Song for YouTube
Published · by Loopin
YouTube turns anything louder than about −14 LUFS down and leaves quieter songs quiet. So a raw Suno export is often too quiet, a slammed one gets flattened, and a −14 LUFS master with a −1 dBTP ceiling plays back exactly as you made it.
Measure the raw Suno export first
Many raw Suno exports sit well below −14 LUFS; our quiet Suno songs post explains why. YouTube doesn’t turn quiet audio up, so an unmastered upload sits a few decibels under every other music video and sounds weaker, even though it isn’t worse.
The opposite problem comes from re-mastering the export with a heavy limiter to −8 LUFS. YouTube turns that down about 6 dB, and what’s left is a flat, crunchy song at normal volume. Measure before you process: if it’s already near −14 LUFS, it needs tone work, not loudness. A free meter plug-in or any editor with a LUFS readout is enough for this.
Master to −14 LUFS with a −1 dBTP ceiling
Master the Suno song free online with the default feel: it exports a 16-bit WAV at about −14 LUFS with a −1 dBTP ceiling, which is right on YouTube’s playback level. Nothing gets turned down, nothing sits quiet, and the peaks have room for YouTube’s own encoding.
For rap, EDM or anything that needs density, Punchy (about −11 LUFS) is as far as it’s worth going. It gets turned down about 3 dB, which is fine: the extra density survives. For Club (about −10), check the A/B carefully, because YouTube will remove most of the loudness you added.
Keep the audio clean through the video export
The master isn’t what YouTube receives; your video file is. When you drop the WAV into a video editor, check the audio track sits at 0 dB gain with no auto-normalise or “enhance audio” switched on, and export at the highest audio bitrate your editor offers.
Match the project sample rate to the video project, typically 48 kHz, so the editor doesn’t resample badly. And don’t put a lyric-video template’s built-in music limiter on top; a second limiter undoes the master.
Check Stats for Nerds after upload
Once the video is live, right-click the player and open Stats for Nerds. The line “Volume / Normalized” shows the content loudness: Production Advice explains how to read it. A value around 0 dB means YouTube left your song alone; a positive number like 5 dB means it was that much louder than the target and got turned down.
If you see a big positive number, your master was louder than it needed to be. If the content loudness reads negative, it’s quieter than most music on the platform. Either way, adjust the feel and upload the next song closer to −14. Check again a day after upload; the value can take a little while to appear on a fresh video.
Fix what YouTube’s speakers expose
YouTube is heard on laptops and phones as much as on headphones. Before uploading, play the master on a phone speaker: if the bass disappears, add a little saturation on the bass in the mix or try Warm; if the vocal gets harsh, try Vintage or dip 1.5 dB around 5 kHz.
Then re-master the track free and compare against the first version with the loudness-matched A/B. For Shorts and other short-form edits, see mastering an AI song for YouTube and LUFS for YouTube.
Frequently asked questions
What LUFS should a Suno song be for YouTube?
About -14 LUFS integrated with a -1 dBTP ceiling. YouTube normalises louder audio down to around that level.
Does YouTube make quiet songs louder?
No. YouTube turns loud audio down but leaves quieter audio as it is, so an unmastered Suno export can sound weaker than other music videos.
How do I see if YouTube turned my song down?
Right-click the player, open Stats for Nerds and read the content loudness next to Volume / Normalized. Around 0 dB means no change; a positive value is how much louder than the target it was.
Should I master louder for YouTube?
No. A master louder than about -14 LUFS just gets turned down. Up to about -11 LUFS is fine for dense genres; beyond that you lose punch for nothing.
What audio settings should I export my YouTube video with?
Keep the audio at 0 dB gain, turn off any auto-normalise, use 48 kHz if the video project is 48 kHz, and pick the highest audio bitrate your editor offers.
Is -14 LUFS right for both Spotify and YouTube?
Yes. Both play back around -14 LUFS, so one master works for both.
