Total Recall VR: Statement on Use of Recordings for Legal Proceedings

Prolancer confirms that the TRC audio file format that is used to store audio and meta data for recordings on Total Recall VR recorders is suitable for use as evidence during legal proceedings. TRC audio files are a tamper proof file format and tools are available to detect and prove without any doubt that tampering with the information stored in the file has or has not occurred.

We confirm that:

  1. The TRC file format contains a watermark that identifies the recorder that produced the recording.
  2. Metadata information about the recording is stored in the file. This information identifies the time of recordings and the parties involved in the conversation.
  3. The file contains information that can be used to detect tampering with the content that is stored in the file.
  4. Our PC applications provide a mechanism to check the integrity of the information that is stored in the file.

Are the recordings acceptable in court? 

Ultimately this is a question for a legal professional in your particular jurisdiction.

However, we are aware of recordings from Total Recall VR systems being used for legal processes in numerous countries around the world, and to date have never been informed of Total Recall VR recordings not being accepted for use in legal proceedings.

For example, on March 6th 2016 CBS News (USA) broadcasted a story titled “King of Coal” in which it explained how a CEO of a major company was convicted of workplace safety crimes which resulted in 29 deaths. During the story the 60 Minutes show showed the actual Total Recall VR equipment which captured the recordings which were used in the court case to prove the crimes. Segments of the recordings were also aired during the story.
