Protect an audio file :
complete guide 2026
3 methods for protect an audio file legally — a complete comparison of legal validity, timelines, costs, and what to do in case of plagiarism.
Why protect an audio file — even if it is automatically protected
An audio file is protected by copyright from the moment it is created — with no formalities. But this protection cannot be proven. In the event of a dispute or plagiarism, you must prove that you created the work before rather than the other party.
This is the crucial distinction to understand before protect an audio file :
✅ What the law gives you automatically
- Copyright from the moment of creation
- Permanent moral rights to the work
- Protection across the EU and in 180+ countries
❌ What the law does not give you automatically
- Proof of the creation date
- A document admissible in court
- Traceability in case of plagiarism
The fundamental rule: for protect an audio file effectively, you must create dated and certified evidence of authorship by an independent third party — before any external sharing.

2. Soleau Envelope — INPI
TheINPI's digital Soleau envelope is the traditional method for protect an audio file through a French government body. It creates a proof of creation that is officially recognised by French courts.
Positive points
- Official recognition by French courts
- €15 per envelope
- Valid for 5 years, renewable
- Government body
Limitations
- Processing time of 15 working days
- Limited file formats
- Interface not well-suited for artists
- No tracking dashboard
- Less suitable for multiple digital files
3. Metadata and copyright notices
Adding your author information into the audio file's metadata is a simple and useful step — but is not legal proof on its own.
What to include in your metadata:
- Author's name or pseudonym
- Creation date
- Statement:
© First Name Last Name — Year - Link to your TuneLockr certificate
Important: metadata can be changed or deleted — it does not constitute legally enforceable proof of prior creation. Use this method as a supplement to a TuneLockr or INPI deposit, never on its own.

Protect an audio file before publishing it on YouTube or Spotify
If you are publishing your audio file on a streaming platform, here is the correct procedure:
Register on TuneLockr before anything else
Before sending your file to a distributor, label, or collaborator — upload it to TuneLockr. The certificate timestamps your creation before any release.
Distribute via a service with Content ID
Use a distributor that enables YouTube Content ID — DistroKid, TuneCore or CD Baby. This allows YouTube to automatically detect and monetise any use of your audio file.
Add copyright metadata
In the ID3 tags of your MP3/WAV file, include your name, the date and your TuneLockr certificate number. In the YouTube description, include © and the year.
Declare to SACEM if applicable
If you are a member SACEM, declare your track before its public release. SACEM collects royalties upon exploitation — TuneLockr protects your authorship. Both are complementary.
