Master your Suno tracks — free, in your browser
Suno gets you a great song. TrackGleam gets it finished — streaming-ready loudness, tamed harsh highs, a firmer low end, and a clean stereo image. Download your track from Suno, drop it in here, and master it in seconds. Nothing uploads — your audio stays on your device.

How it works — three steps
Download your track from Suno
In Suno, open your song and use its own Download button (⋯ → Download → MP3 or WAV). This is the file we'll master — TrackGleam never touches your Suno account.
Drop it into TrackGleam
Open the mastering studio and drop the file onto the upload zone (or click to browse). It's decoded right in your browser — nothing is sent anywhere.
Master it and download
Hit Gleam for a free, watermark-free master, or preview the premium GleamAI master. Compare against the original, then download your WAV or MP3.
What it fixes on AI-generated songs
Suno and other AI music tools are great at ideas, but their exports tend to share a few finishing problems. TrackGleam's engine is tuned to address exactly these:
- Too quiet. Raw exports often sit well below streaming level. The engine brings you to a safe ~−14 LUFS so your track holds its own next to commercial releases.
- Harsh, brittle, or metallic highs. Subtractive EQ, de-harshing, and a spectral-resonance suppressor smooth the shimmer without dulling the track.
- Thin low end. Low-frequency balancing and mono-below-bass keep the bottom firm and translatable on phones and club systems alike.
- Unstable stereo. Correlation-aware width control keeps the image wide but mono-safe, so nothing collapses on a single speaker.
Mastering polishes a finished mix — it can't reconstruct audio that's already damaged, but on most Suno exports the difference is immediate.
Is this allowed?
Yes — and it's deliberately built to stay that way:
- You own your paid Suno tracks. On Suno's paid plans, Suno assigns you the rights to the songs you generate, so you're free to edit, master, and release them. (On the free plan, tracks are for non-commercial use — check Suno's terms before releasing.)
- We only touch files you've already exported. TrackGleam masters a track you downloaded with Suno's own button. It doesn't log into your account, read the Suno site, scrape anything, or bypass any protection.
- Your audio never leaves your device. All processing happens locally in your browser. For the optional AI master, only numbers — loudness, tone, stereo — are sent, never the audio.
- Independent tool. TrackGleam is not affiliated with, endorsed by, or connected to Suno.
This isn't legal advice. If you're releasing commercially, review Suno's current terms for your plan.
FAQ
Is it allowed to master my Suno tracks with TrackGleam?
Yes. TrackGleam only works on a file you've already downloaded from Suno using Suno's own Download button. It doesn't connect to your Suno account, scrape the site, or bypass anything. On Suno's paid plans you own the rights to your tracks and are free to edit and release them; on the free plan, tracks are for non-commercial use, so check Suno's terms before releasing. TrackGleam is not affiliated with, endorsed by, or connected to Suno.
Does TrackGleam upload my Suno track?
No. Your audio file is decoded and mastered inside your browser, on your own device — it is never uploaded to a server. For the optional AI version, only numeric measurements (loudness, tone balance, stereo profile) are sent; the audio itself never leaves your device.
What does it fix on Suno songs?
Suno exports are often quiet, a little harsh or metallic in the highs, and thin in the low end. TrackGleam brings the track up to streaming-ready loudness (about −14 LUFS), tames harsh upper-mids and brittle highs, firms up the low end, and keeps the stereo image mono-safe — the same craft a mastering engineer applies, done automatically.
Do I need a Suno subscription to release my track?
To release commercially, yes — Suno grants commercial rights to songs made on its paid plans. Free-plan tracks are for non-commercial use. TrackGleam doesn't change that either way; it only masters the file. Always check Suno's current terms for your plan.
Does it work with Udio and other AI music tools?
Yes. TrackGleam masters any WAV or MP3 you drop in, so it works the same way with Udio, Riffusion, or any other tool — download your track, drop it in, and master it. It also works on tracks you recorded or mixed yourself.
