What You Get

Every Certified Audio Includes

Forensic Report

A court-ready PDF documenting every detail of the forensic audio acquisition per ISO 27037 guidelines. Admissible as digital evidence in civil and criminal proceedings.

Digital Signature

A qualified digital signature under eIDAS (EU 910/2014) seals your certified audio file. Any alteration breaks the cryptographic seal and is immediately detectable.

Certified Timestamp

Legally binding date and time from a Qualified Trust Service Provider (RFC 3161). Impossible to backdate or alter.

GPS Coordinates

Certified GPS coordinates prove exactly where the audio was recorded. Location data is locked at the moment of acquisition, confirming where the conversation took place.

Device Metadata

Model, OS, microphone data, and network information captured during the recording. A complete device fingerprint that makes the origin of the audio verifiable.

Chain of Custody

Every step from the first second to final certification is logged and cryptographically sealed. An unbroken chain of custody guarantees your audio evidence has never been tampered with.
