Audio Documentation Certificate
Please Don't
by Marsyn
Timestamped: 11 Aug 2026
In plain terms: this page documents when this audio file was submitted and preserves an independent, verifiable technical record of it that anyone can check.
This certificate documents the existence of an audio file at a specific point in time. It does not prove ownership, originality, or legal rights. It is not a substitute for copyright registration with a government authority.
Chain of Independent Evidence
This documentation relies on multiple independent sources — not a single self-issued signature.
Timestamp verified by Sectigo
Independent third-party Time Stamping Authority (RFC 3161)
Audio scanned against millions of recordings
ACRCloud similarity analysis — independent content recognition
Portion examined: Only part of this recording was examined: 2:14 to 4:14 of 6:28, which is 30.9% of the audio. Material outside that window was not compared against any database.
Matched 2 recordings across 2 different artists: none covers more than 44% of the audio scanned. Overlaps that short are not evidence of a specific source — they more often mean the section is unremarkable. Nothing here identifies this recording as anyone else's.
Audio Fingerprint (SHA-256)

This timestamp was issued by a trusted third-party Time Stamping Authority (TSA) and cryptographically attests that the audio file's SHA-256 fingerprint existed at the recorded time. It is applied to that fingerprint, not to the declarations on this page, and it cannot be backdated or altered.
The timestamp token issued by Sectigo is available as a file. It is a standard RFC 3161 token, so you do not have to take our word for any of this — you can check it with OpenSSL on your own machine, against the audio file you hold.
1. Check the token and its date
openssl ts -reply -in audiverify-timestamp-AUD-2026-HCRSYFRT.tsr -textPrints the time Sectigo signed, and the SHA-256 value that was submitted to it. Anyone can run this; it needs no file from you and nothing from us.
2. Check that the token corresponds to your file
openssl ts -verify -data your-audio-file.wav \
-in audiverify-timestamp-AUD-2026-HCRSYFRT.tsr \
-CAfile sectigo-tsa-chain.pemRun this against the audio file you hold. It hashes your bytes and compares them with the value inside the token, so only someone who has the original file can complete this step. It is not a check against any copy of ours.
The creator declares: AI training use not permitted.This is the creator's stated permission, recorded with the certificate. The RFC 3161 token covers only the audio fingerprint, not this declaration. Audiverify documents this declaration and does not monitor or control how third parties use the file.
- Purchased samples or beat packs (licensed)
- Third-party samples (with clearance)
This records what the creator declares they used. Audiverify does not verify these sources, confirm exclusivity, or clear this track for distribution or social platforms — distributors make that determination separately.
Audiverify detects whether the uploaded file carried C2PA Content Credentials. It does not issue, sign, or validate them, and their absence does not indicate anything about the work.
