EdiTracker

The unique software for audio authenticity analysis

Application

Fast analysis of audio authenticity in specialized laboratories and forensic science centers.

Functionality

Forensic investigation of audio recordings authenticity:

• Testing and calculating of technical characteristics of the recording device: total harmonic distortion (THD), frequency response, detonation, parasite amplitude modulation.
  
  
  
  
  
• Finding the traces of previous digital processing. Digital processing of analog signal leaves the traces in the signal which can be automatically detected by EdiTracker.
  
  
  
  
  
• Search for the traces of editing by the harmonic’s phase shift. EdiTracker automatically finds the harmonic components of the signal and investigates the continuity of the harmonics’ phase.
• Background noise scanning - analysis of the background noise continuity. An unjustified abrupt change of its characteristics can be suggestive of previous editing.
• Auditory analysis - detailed list of linguistic features of tampering.
• Final report is generated automatically.

Highlights

• Automation of finding and analysis of “suspicious” spots in the recording.
• Automation of recording device identification.
• Visualization of all steps of analysis.
• Automatic logging of each type of analysis and final protocol composition for the expert’s report.
• Built-in instructions for each type of analysis.
• Fastening of authenticity examination procedure and increasing reliability of the expert’s conclusion.
• Practical recommendations for audio authenticity examination.
