How Trace works
Evidence, not guesswork.
01 · Upload
Your master goes in.
Upload WAV, MP3 or FLAC. Trace reads the audio structure and checks available provenance and metadata.
02 · Analyze
Trace looks inside the audio.
Forensic audio signals are compared and mapped across the track. Trace builds a spectrogram and identifies localized evidence regions.
03 · Report
See where the evidence is.
Your report combines provenance, master-level signals and timeline evidence. Click the waveform to hear the regions Trace is referring to.
04 · Go deeper
Deep Forensics is next.
Where deeper examination is useful, stem-level analysis can separately examine vocals, drums, bass and other elements.
What the result means
Trace is a forensic screening tool. It reports characteristics and evidence found in the submitted audio; it is not proof of origin. Results remain available in My Scans.

Full results, every time
See the findings and evidence coverage from your master scan in one report.
Only completed scans count
Failed processing does not use a credit. An inconclusive completed report still counts as a scan.
Your reports stay accessible
Reopen a saved report in My Scans without spending another credit.
A few useful answers
What does one credit cover?
One completed master scan, including its full current report. These packs cover master scans only.
Do the two free credits reset each month?
No. They are an introductory allowance for new verified accounts. When you need more scans, choose a credit pack once purchases open.
How long will purchased credits last?
Purchased credits will be valid for 12 months from purchase. There is no subscription and no automatic renewal.
Can I reopen a report for free?
Yes. Opening a saved report does not cost credits. Running a new analysis uses one credit.
Does a report prove that a track is AI-generated?
No. Trace reports available provenance and AI-related characteristics, with evidence coverage and limitations. Findings are indicators, not proof of origin.
Simple packs. Complete master reports. No subscription.

What we found
Already in My Scans
This file has already been analysed
Only an identical file in your own account is matched. An edited export is treated as a new file.
Explainer
Can MP3 compression change an AI music scan?
A different export is a different input. Here is how to interpret a changed scan without treating compression as proof of a track’s origin.

ai musicaudio formats
You scan a WAV master, export an MP3 and scan again. The reports differ. Has the music’s origin changed?
The production history has not changed simply because you exported another file. The submitted representation has changed, and that distinction matters when interpreting measurements.
What research supports
AI-Generated Music Detection and its Challenges, by Afchar and colleagues, discusses audio manipulation and generalisation as detection challenges. It also warns about dataset shortcuts, including codec differences. This does not establish how every detector behaves on every MP3 export.
A changed result therefore needs a limited reading: the analysis responded differently to two submitted files. It does not, by itself, establish why.
Compare files with a clear question
For your own production records, keep the original export and the delivery copy. Record the format and export settings so the files can be identified later. If you are comparing reports, use descriptive version names and note which report belongs to which file.
Avoid treating a scan of one version as a certificate for every later export. Equally, a change in the report should not be treated as evidence that the artist added or removed AI from the session.
Playback copies and analysis files serve different purposes
A lightweight listening copy can make a website easier to use. That copy should be clearly distinguished from the file examined by the analysis. Faster playback is a product delivery choice; it does not validate a different detection result.
For any service you use, ask which file the report describes. The answer should remain clear when you return to the report or share it with someone else.
A useful record to keep
- The file originally submitted for analysis.
- Its format, export date and version name.
- The report attached to that submission.
- A separate record of any listening or delivery copies.
There is no universal rule that MP3 means AI or that WAV means human. Format describes a file, while authorship describes a production history. Keep those questions separate when you read a scan.

Can audio processing remove an AI watermark?
Some processing can weaken detection in specific systems. That is not a universal watermark-removal recipe—or proof that a track is human-made.

AI audio watermarks and detection: what is the difference?
An inserted watermark and a forensic audio finding are different clues. Neither a missing marker nor a reassuring scan establishes human authorship.

Terms & Conditions
TRACE is currently in testing. This page outlines the current service. Final purchase terms and privacy information will be published before payments and public launch.
Understanding your report
TRACE screens submitted audio for provenance, metadata and measurements associated with AI-generated material. A result is not proof of who created a track. Ordinary production and processing may explain suspicious measurements, and a scan may miss AI-generated material.
Your uploads and account
Only upload audio you have permission to submit. Saved scans are accessed through your signed-in account. An identical upload in your own account can open its saved report for free; a new analysis requires confirmation of its displayed credit cost.
Credits and pricing
Credit purchases are not yet enabled. Launch packs are €9 for 10 credits, €19 for 25 credits and €39 for 60 credits. One credit covers one completed master scan; failed processing does not consume a credit. Purchased credits will be valid for 12 months from purchase, with no subscription or automatic renewal. Final purchase and refund terms will be published before checkout opens.
Audio storage and privacy
Audio is stored to support saved-report playback and is automatically deleted 30 days after a completed scan. The report remains in My Scans after the audio expires. You can delete a scan earlier at any time; deleting a scan removes its saved report, stored audio and playback copy, and revokes its report invitations. A fuller privacy policy will be published before public launch.
Optional Google Analytics
If you accept analytics, TRACE uses Google Analytics to understand visits and how features are used. Google receives usage events and browser/device information and processes connection information such as your IP address to provide the service. Analytics may store cookies in your browser. We do not send your audio, filenames, email address, report findings, private report IDs or invitation tokens in analytics events. Advertising features are disabled. Rejecting analytics does not affect scanning or sharing. You can change your choice at any time using the Analytics preferences button below. Essential sign-in and security storage remains necessary to use your account. Read Google’s privacy policy for information about Google’s processing.
