Audio Visual Forensics


Analysing and enhancing audio and visual evidence


The evidence obtained from audio visual forensics, now more than ever, can be critical to the outcome of a criminal or civil case. CCTV networks
and sophisticated mobile phones and cameras have the ability to capture the world around us, however in its native format footage is often so badly distorted that it is useless or lacks impact. CYFOR offers a complete enhancement service to ensure you get the most from your evidence. Our audio visual forensic suite allows us to work from a variety of media to the highest possible standards.

The processes applied include;
Dialogue enhancement & transcription CCTV enhancement, de-multiplexing & frame averaging Video level adjustments
We can extract footage from CCTV systems, VHS tapes, mobile phones, cameras and dictaphones using our computer forensic and mobile phone
laboratories. CYFOR analysts can then work with your footage to improve it to an optimum level, so that it can be presented in a clear and understandable form.


Audio Forensic Investigations

Audio can be recorded on an increasingly diverse range of digital devices including mobile phones, Dictaphones, covert recording devices, cameras and laptops.  Such audio in its native format is often distorted and would be useless or lack impact.  CYFOR offer a full range of audio investigative services provided at the highest possible standard:

  • Dialogue Enhancement
  • Transcript Services
  • Audio Authentication
  • Tampering Investigations
  • Audio Enhancement 


Video Forensic Investigations

The proliferation of CCTV equipment on virtually every street corner, outside many businesses premises and even fitted to many domestic properties, has created an increase in the amount of audio and video evidence available for examination.

Evidence of this nature is heavily relied upon in court but often needs enhancing to ensure that it is clearly presented.  CYFOR’s experienced video analysis team uses state of the art equipment to enable the following:

  • CCTV and Video Footage Enhancement
  • Demultiplexing
  • Footage Restoration
  • Visual Authentication
  • Tampering Investigations
  • Enhancement & Speed Correction
  • Highlighting & Pixilation
  • Format Conversion
  • DVD Compilation

Phonetic Disclosure

In our increasingly litigious environment, the ability to search and disclose electronically stored information (ESI) is common place.  Audio is often not considered in litigation, disputes or forensic data searches and may contain valuable information.

As with the eDisclosure process followed for more traditional forms of ESI, tools are now available to automate the process, review and analysis of audio recordings.  CYFOR’s speech technology can accurately conduct complex searches for key words or phrases and reduce the time and resource needed to analyse audio recordings.  Features include iterative search, file based tagging and dataset filtering.
