The file stays on your device. Your browser makes a digital fingerprint of the file. TimeBinder records the fingerprint and the time, not the file.

Short answer

Often yes, if the recording is relevant, was lawfully made and can be shown to be genuine. A court may look at who made it, who is speaking, whether it was edited and how it was kept. Recording laws differ by country and state, and some require everyone’s consent, so check before you record or rely on one.

What courts look for

In US federal courts, evidence must be authenticated (Federal Rule of Evidence 901). The rule’s examples include testimony of a witness with knowledge, an opinion identifying a person’s voice based on hearing it under circumstances that connect it with the alleged speaker, and the item’s distinctive characteristics with all the circumstances. Courts therefore ask who recorded it, on what device, who is speaking and whether it was altered. Rule 902(14) allows a hash-based certification for data copied from a device.

Was it lawful to record? In the US federal wiretap law, it is generally not unlawful to intercept a call where you are a party or one party has consented, unless done for a criminal or tortious purpose (18 U.S.C. § 2511(2)(d)), but other countries and states can require everyone’s consent. Check local law first.

AI voice cloning means a convincing recording is not enough on its own. See how to tell if audio is AI-generated and is voice cloning legal.

Keeping the original recording

Keep the original audio file, not just a forwarded or compressed copy, and keep the device or account it came from. Note when and where it was recorded and who was present. A TimeBind records a SHA-256 fingerprint of the exact file and a time, anchored to Bitcoin. The fingerprint is made in your browser and the file is not uploaded.

Later, you can show the file is unchanged since that time. A TimeBind shows a file existed by a recorded time and has not changed since. It does not register copyright, is not legal advice and does not by itself prove who made the file. It does not show who is speaking or that the speech is genuine. Ask a lawyer about recording rules in your place.

Frequently asked questions

Is a voice memo admissible in court?

It can be, if it is relevant, lawfully made and authenticated. A witness who recognises the voice, plus the original file, helps.

Is a secret recording admissible?

It depends on the country and state. Some places allow recording by a party to the conversation, others require everyone’s consent, and a court may exclude unlawful recordings.

Can a recording be faked with AI?

Yes. Voice cloning can produce convincing speech, so courts and parties may question a recording’s authenticity. Original files and chain of custody matter.

Does a timestamp prove a recording is real?

No. It only shows the file existed by a recorded time and has not changed since.
