Make your AI track sound released.
Clean the metallic ringing and watery noise, master to streaming loudness without crushing the dynamics — and get a before/after report that shows exactly what changed.
The chain
Passport of the input
Loudness, crest factor, range and stereo image are measured before processing.
EQ, dynamics, width
24 sound profiles, from classical and trap to voice, or a reference track to match.
Artifact removal
Metallic ringing and watery noise from AI generation or stem separation.
True-peak limiting
Oversampled ceiling at −1.0 dBTP, safe for streaming encoders.
Output measured again
If the target is missed, the report says so and says why.
WAV, FLAC, MP3
With a measurement report you can hand to a label or distributor.
Every master comes with its numbers.
Hand it to a label, a distributor or your mix engineer. If a target was not reached, the report says so and explains the reason instead of hiding it.
| METRIC | IN | OUT | STATUS |
|---|---|---|---|
| Loudness | −18.4 LUFS | −14.0 LUFS | target met |
| True peak | −0.3 dBTP | −1.0 dBTP | under ceiling |
| Range | 7.1 LU | 6.4 LU | kept |
| Crest | 11.2 dB | 9.8 dB | kept |
| Stereo | 0.65 | 0.61 | kept |
Listen: before / after
A real song made with Suno, 20 seconds. Switch while it plays — same moment, levels matched, so you hear the sound, not the volume.
| Whole song | Suno export | Echoteka master |
|---|---|---|
| Loudness | −13.6 LUFS | −14.0 LUFS |
| True peak | −3.2 dBTP | −2.8 dBTP |
| Loudness range | 5.1 LU | 4.1 LU |
This export was already near Spotify’s level, so mastering changed little: a touch more clarity, safe peaks — and 1 LU less range. Full breakdown. Track used with the author’s permission.

Loudness Penalty on Streaming: What It Is and How to Check It
A loudness penalty is the turn-down a streaming service applies when your master is louder than its target. Learn how to read it, check your own track for free, and decide whether…
Does it work with Suno tracks?
Yes — that is what it is built for. Artifact cleanup runs before mastering, and the report shows what it changed.
Will my track still sound like my track?
Dynamics and stereo are measured before and after. If processing would flatten them, the report says so.
