Remove AI traces from your track
Suno and Udio leave inaudible traces in a track: high-frequency steganography above 16 kHz, artifacts at the seams of generative blocks, and their decoder's spectral fingerprint. Magic Master finds and removes the AI fingerprint while preserving sound quality, and runs a full mastering pass at the same time — all in one go.
Clean up my track →How it works
HF steganography
Suno and other AI generators embed inaudible high-frequency markers above 16 kHz. We cut them with an 8th-order Butterworth filter — the musical content stays untouched, since the highest harmonic of live instruments sits around 12–14 kHz.
Block artifacts
The neural net builds a track in 0.3–0.5 second blocks, leaving sharp energy jumps at the seams. Crossfade smoothing removes these seams without touching the music's dynamics.
Generator fingerprint
The network's decoder leaves a row of narrow spectral peaks at fixed frequencies — they give the generator away. We shift the pitch by 7 cents, less than a tenth of a semitone: the peaks move off their spots while tempo and length stay the same.
Remove the trace in 3 steps
- Upload your track — WAV or MP3 from Suno, Udio, or another AI generator.
- Cleanup mode is already on — just hit "Master".
- Download the result — a clean WAV or MP3 with no AI trace left.
Being upfront about what we do
This isn't faking authorship. Cleanup removes the generator's technical traces from the audio, but it doesn't change how the track was made or turn it into a 'human-made' one.
Complying with a specific platform's or distributor's AI-music policy is the user's responsibility. We remove technical artifacts in the audio — we don't change how or with what the track was made.
FAQ
Upload your track to Magic Master — AI-trace cleanup mode (SunoFix) is on by default. The service cuts HF steganography above 16 kHz with an 8th-order Butterworth filter, smooths block-boundary artifacts with a crossfade, and removes the generator's spectral fingerprint with a 7-cent pitch shift (length stays the same). The output is a clean WAV or MP3, and processing takes about a minute.
No, most markers are inaudible to the human ear: Suno's and Udio's HF steganography sits above 16 kHz, outside the typical range of perception, and block-boundary artifacts are microscopic energy jumps within 0.3–0.5-second tokens. Only spectral analysis reveals them, not the ear. But they are not the only thing that gives away machine origin: AI detectors judge by the statistical signature of the generation itself, and removing the mark does not remove it.
There are no guarantees, and we won't promise any. Cleanup removes the generator's marks and spectral fingerprint from the audio, but newer detectors are trained on how the generation itself sounds — its timbre and structure — and cleanup doesn't change that. Most importantly: if a platform or distributor requires you to disclose AI use, disclose it — cleanup doesn't change where the track came from.
Yes. AI digital fingerprint removal is free on every plan (Free, Pro, Studio). Basic mastering: Free account — 1 per UTC day; guest — 3 per calendar month. PRO modules (Denoiser, Dynamic EQ, etc.) — 1 token = 1 mastering.
No. The cut happens above 16 kHz — beyond the highest harmonic of live instruments (12–14 kHz), block seams are smoothed with a crossfade, and a 7-cent pitch shift — less than a tenth of a semitone — changes neither tempo nor length. In tests, HF energy drops from ~2.8% to ~0.16% with no audible loss of quality.
