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.

Creating music with AI? Keep these records before release
Save the sources, versions and production notes that explain your track. An AI music scan cannot reconstruct the creative process for you.

ai musicmusic productionartist guides
You have used AI somewhere in a production and turned the result into a track you want to release. Before the final export, keep a record that helps explain what you actually made.
This is practical production guidance, not a detector benchmark. It is useful for collaborations, later revisions and conversations about the origin of a track.
Describe the role of AI
Write down which tools contributed material and what that material was: a vocal, accompaniment, texture or another source. Note the relevant generation date and visible tool version where available.
Describe your own work too. Composition, recording, selection, arrangement and editing are different contributions. A single “AI-assisted” label can leave those details unclear.
Save the source material
Keep the generated exports you used, your recordings and the working session. If you replace a generated part with a new performance, preserve the versions so the change can be explained later.
Retain useful generation references such as prompts or job identifiers in your private records. They do not have to be published with a report to be useful to you.
Keep the delivery versions clear
Give the premaster, final master and delivery copies descriptive names. Record which version was sent to collaborators and which was submitted for analysis. Keep original stems distinct from components estimated by separating a finished master.
These records make comparisons easier without assuming that two similarly named files have identical content.
Treat a scan as one piece of evidence
Research on hybrid human–AI music studies the challenge of detecting generated components in a mix. Rigaud and colleagues’ 2026 preprint uses controlled vocals-and-accompaniment mixtures; it is not a validation of every real-world production.
A master scan does not describe your complete workflow. No significant findings are not a certificate of human authorship, and flagged time is not a measure of your creative contribution.
Separate production records from permission questions
Keeping good notes does not establish that every source can be commercially released. Check the applicable terms and permissions for your actual tools and material separately. This article does not assess a provider’s current licensing terms.
The goal is a production history you can understand months later: what came from where, what you changed and which file became the release. Keep that history alongside any scan rather than expecting the scan to replace it.

Human and AI in one track: why yes or no falls short
A generated vocal over human instrumentation raises a different question from an entirely generated song. A master-level label cannot describe every contribution.

Mastering changed your AI scan. What does that mean?
A changed scan after mastering does not explain how the music was created. Keep the versions and investigate the reported evidence in context.

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.

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.
