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.

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.
Catalyse TRACE Research · 2026-10-03 · 2 min read
ai musicmusic productionhybrid music
A musician records the instruments and uses a generated vocal. Another writes the song but develops an AI-generated accompaniment. Both tracks involve AI, yet their production histories are different.
A single yes-or-no label cannot explain those contributions. Before interpreting a scan, decide what question you are trying to answer: whether AI was used anywhere, which element was generated, or what evidence is present in the delivered file.
What hybrid-music research examines
Rigaud and colleagues’ 2026 preprint, Detection of AI-generated stems within hybrid human-AI music, studies controlled mixtures of human and generated vocals and accompaniment. It illustrates why detecting a mixed track and attributing a generated component are different problems.
Its setting is limited: two broad components and simulated hybrids, rather than a validation of every commercial generator, genre or finished master. It does not establish the origin of any particular artist’s release.
Why a timeline is not an ingredient list
Several elements can overlap in a flagged region. The timeline locates measurements in the master; it does not automatically assign them to the singer, a drum sample or a background texture.
Evidence coverage is consequently a measure across time. It does not count generated instruments or estimate the proportion of creative labour performed by software.
Describe the process, not just the label
For an AI-assisted production, keep a short record of what happened. Which material came from a generator? Which parts were recorded or composed separately? What was edited, arranged or replaced? Which exports belong to the final version?
These are production descriptions. They can be useful even when a detector finds no significant signals, because the absence of a finding does not establish the absence of AI use.
What a clear report can contribute
A report can identify findings in a submitted master and help you inspect them. Stronger attribution needs additional evidence, such as original sources and a documented production history.
TRACE’s screening results should be read within that scope. Research into hybrid tracks motivates further investigation; it is not a claim that a master scan can already reconstruct every ingredient.

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.

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.
