Undetectr

Undetectr is a browser-based AI artifact removal engine that strips the digital fingerprints AI music generators embed in audio, so tracks clear distributor screening. It accepts MP3, WAV or FLAC from Suno, Udio and other AI platforms, processes them in under a minute without leaving your browser, and exports in the same three formats ready for distribution.

What is Undetectr?

Undetectr is a web-based tool that removes AI-generated audio artifacts before music distribution. Its core job is to get AI-created tracks through the detection checks run by DistroKid, Spotify, Apple Music and Amazon Music at ingestion. You upload a file, the engine strips detection traces locally in the browser, and you download a cleaned track. Nothing installs, and your audio never reaches a server. Lifetime access is a single €39 payment.

What makes Undetectr stand out?

• Six-layer removal engine — Spectral artifact removal, temporal pattern normalisation, dynamic range processing, metadata sanitisation, stereo field correction and speed adjustment run together, covering every trace class AI generators leave behind.
• Provenance watermark and content-credential removal — Strips the inaudible provenance watermarks and embedded content credentials that distributors scan for at ingestion.
• Metadata sanitisation — Removes generator tags and model hashes such as suno-v4.2 from the file itself, not just the audio.
• Platform-specific mastering — Masters to each destination's published loudness spec: -14 LUFS for Spotify, YouTube Music, SoundCloud and Amazon Music, -16 LUFS for Apple Music, -15 LUFS for Deezer, all at -1 dBTP.
• Sound Match — Reverse-engineers a prompt from any reference track, so you can recreate a sound you already like instead of guessing at prompts.
• Bulk Suno downloader — Paste a public Suno playlist URL and pull the whole library as MP3s in one pass, routed through Suno's own official download endpoint on your account allowance.
• In-browser processing — No installation, no command line, no upload. Typical tracks finish in under a minute.
• Flexible formats — MP3, WAV and FLAC in and out, at 24-bit. WAV or FLAC recommended for distribution.
• Lifetime pricing — One payment, not a subscription. Unlimited processing and every future tool included.

Who is it for?

• Independent AI music producers generating with Suno or Udio who have hit distributor rejections or takedowns.
• DJs and electronic musicians releasing at volume who need a repeatable process rather than manual cleanup per track.
• Beatmakers and content creators who have been doing this by hand in Audacity and want it done properly in a minute.
• Artists monetising AI music on streaming platforms that enforce AI-content policies.

What can you do with Undetectr?

• Clean tracks before distribution. Upload an MP3, WAV or FLAC from Suno or Udio, run artifact removal, download in whichever format your distributor wants.
• Master for the destination. Set the target platform and the track comes out at the correct LUFS and true-peak spec, so it sits properly alongside everything else in a playlist.
• Export an entire Suno playlist. Paste a playlist URL, select what you want, download it as a ZIP of MP3s.
• Recreate a reference sound. Feed Sound Match a track you like and get a prompt that gets you close.
• Estimate streaming revenue. The earnings calculator returns a per-platform royalty estimate across Spotify, Apple Music and YouTube Music before you commit to a release.

How does Undetectr work?

Three steps: upload a track, run the engine, download the cleaned file. Removal usually completes in under a minute, and a before-and-after spectrogram shows exactly which fingerprints were removed. Because everything executes in the browser tab, your unreleased audio never leaves your machine.

FAQ

Is Undetectr legal to use?

Processing audio you own is ordinary post-production. Every technique the engine applies — spectral editing, dynamic range processing, metadata cleanup, stereo correction — is standard practice in professional mastering. You remain responsible for following your distributor's disclosure rules.

Will my music sound different after processing?

The processing is designed to sit below the threshold of human perception, targeting only the signal ranges detection systems scan. The mastering stage does change loudness, deliberately, to hit the target platform's published spec.

Which platforms is it built for?

DistroKid, Spotify, Apple Music, Amazon Music, YouTube Music, Deezer, SoundCloud, Bandcamp, QQ Music, NetEase Cloud Music, Soda Music and 150+ more.

Will my track definitely be accepted?

No tool can promise that. Distributors run their own checks and make their own decisions, and one that has already logged a rejection will match a resubmission of the same audio to that record. If you have had a track rejected, switching distributor is usually more effective than resubmitting the same file.

How long does processing take?

Usually under a minute, entirely in your browser, with no installation or technical knowledge required.

What audio formats are supported?

MP3, WAV and FLAC in and out, up to 40 MB per upload, with 24-bit output. WAV or FLAC is recommended for distribution quality. For larger files, export as 44.1 kHz/16-bit WAV first, or 320 kbps MP3 for tracks over about four minutes.
