Forensic Authenticity Analyses of
Audio/Video Evidence

Has the recording or tape been altered, edited, falsified, fabricated or tampered with? Or is the recording a true and accurate audio or video reproduction of the event that it purports to record?

Voice/Speaker Identification or Elimination via Aural-Acoustic- Spectrography

Is the speaker on the recording really John Doe? Or, can we eliminate John Doe as the speaker on the recording?

Digital Enhancement

Can the recording be “cleaned up” for better intelligibility and for a more accurate transcript?

Discourse or Linguistic Analyses of Speech

Used forensically initially as a defence to entrapment, such analyses can determine whether the conversants are talking about the same subject matter, or it can explain to a non-conversant, e.g., jury or fact finder, what the recorded conversants are talking about.

Transcription Development and Verification

Based on our digital equipment and the quality of the original evidence, we may be able to render a highly accurate and unbiased verbatim transcript of the recording(s), which could be an invaluable aid in better understanding the recorded event.

Audio (or Video) Copying From and To Most Any Format

We can reliably copy or transfer a recording in most any format to most any other format. The most useful format to play back an audio recording is on a compact disc, or CD (either an audio CD or data CD). We can provide testimony (affidavit, declaration or live testimony) as to the accuracy and reliability of our copying or transferring procedures in the accurate reproduction of the original.
