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.

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.

Can stems reveal which instrument was made with AI?
Separate tracks can add context, but separating a master does not automatically prove where a suspicious signal originated.

ai musicstemsaudio evidence
A master scan flags a region. The next question is often: was it the vocal, the drums or something else?
Stems can help investigate a production, but the word needs clarification. Original session exports and components estimated from a finished master are different forms of evidence.
Original exports and estimated components
An original vocal or instrumental export can be connected to the session that produced it. A component extracted from a master is an estimate created by a separation process. It should be described that way when used in an investigation.
Keeping the original session and export records helps establish where a stem came from. A filename on its own does not authenticate that history.
What current research cautions
In their 2026 hybrid-music preprint, Rigaud and colleagues investigate vocals and accompaniment. They report that separating a mix does not reliably confine the studied generation artifacts to their originating component. Findings can spread across separated components.
The experiments use controlled two-component mixtures. They do not establish reliable attribution for every instrument in a commercial master.
A flagged stem is not an authorship verdict
If an estimated vocal component receives a finding, that result should not be silently translated into “the singer was generated”. Ask what was submitted, how it was obtained and what the analysis has actually validated.
The same caution applies to a clean result. It describes the analysis of that component, rather than proving its entire production history.
What to retain for a deeper investigation
- Original session exports where available.
- A clear distinction between those exports and separated estimates.
- The corresponding master and musical version.
- Records of generated source material or recorded performances.
Stem analysis is a useful research direction because it asks more specific questions about mixed audio. Its value depends on documented inputs and validation, not simply on producing more tracks from one file.
This article discusses that research direction. It does not announce an available TRACE stem-analysis feature or promise that an instrument’s origin can be confirmed from a master.

Two scans can give different answers for the same track. Understand what that disagreement tells you before treating either result as a verdict.

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.
