Real Suno & Udio tracks, mastered with this tool. Raw AI exports come in around -18 LUFS; here they're brought up to streaming loudness (~-9 LUFS) with peaks under control — louder and cleaner, with the dynamics kept intact.

Why your Suno songs sound quiet
If you have ever exported a track from Suno or Udio and felt it sounds thin, quiet, or weak next to a commercial release, you are not imagining it. AI music generators like Suno typically export around -14 to -18 LUFS, while streaming platforms such as Spotify, Apple Music, and YouTube target roughly -14 LUFS for playback. When your Suno song is quieter than the songs around it in a playlist, listeners turn it up — and then the next track blasts them. Mastering your Suno songs fixes this by raising the loudness to the streaming target, controlling the peaks, and balancing the tone so your AI music holds its own anywhere it plays.
What LUFS means for AI music
LUFS (Loudness Units Full Scale) is how streaming services measure perceived loudness. A raw Suno export at -16 LUFS played next to a -9 LUFS pop master will sound noticeably softer, even at the same volume setting. Mastering a Suno song means measuring its true loudness, then applying gain and limiting so the integrated loudness lands in the streaming-ready zone (around -9 to -14 LUFS depending on genre) without clipping. Our free tool measures the LUFS of every track you drop in and shows you the before and after, so you can see exactly how much louder your AI song became.
True-peak limiting and de-clipping
Loud is not enough — a master also has to be clean. If you simply turn an AI track up, the loudest moments clip and distort. A proper master uses true-peak limiting (we cap output at -1 dBTP) so the song is as loud as possible while staying free of digital clipping artifacts. This matters especially for dense Suno tracks and high-energy EDM, where the peaks are aggressive. The result is a Suno song that is loud, punchy, and distortion-free on phone speakers, earbuds, and big systems alike.
How to master a Suno song in your browser
Mastering your AI music used to mean a DAW, plugins, or a paid service. With this free tool it is three steps, all client-side — your audio never leaves your device.
1. Drop your Suno track
Add up to 30 songs at once (MP3, WAV, FLAC, or M4A). Everything is processed locally in your browser with the Web Audio API — nothing is uploaded to a server, so your unreleased AI music stays private.
2. Auto-master for streaming
The tool analyzes each track's loudness, true-peak, and dynamics, then applies loudness normalization, peak limiting, and tonal balance automatically. Want control? Switch between Loud and Streaming presets, or open Advanced to set clarity, bass, stereo width, and compression yourself.
3. Download and publish
Get a streaming-ready WAV, hear the before/after with the built-in A/B player, then turn your mastered Suno song into a lyric video for YouTube and TikTok — all from the same page.
Get your AI music ready for any platform
Different platforms want different things, but they all reward a clean, properly mastered track. Whatever you are publishing to, the goal is the same: make your Suno song loud enough, clean enough, and consistent enough to compete with everything else in the feed.
Master Suno songs for YouTube
YouTube normalizes loud uploads down, so a brick-walled track just loses headroom for nothing. Mastering to a sensible streaming loudness with true-peak control gives you a clean, consistent sound across your channel — and pairs perfectly with a lyric video.
Make Suno tracks louder for Spotify
Spotify plays back around -14 LUFS. A raw Suno export at -16 or quieter will sound weak in playlists. Mastering brings the perceived loudness up to the streaming target so your AI song sits naturally next to commercial releases instead of disappearing under them.
Normalize AI music for TikTok & Reels
Short-form video is loud and fast. A quiet AI track gets scrolled past. A punchy, mastered Suno song with a strong, consistent level grabs attention in the first second — exactly what TikTok and Reels reward.
