OVERVIEW

With the rise in availability of free audio editing software packages, the editing of audio recordings is more prominent than ever before. Analysis of an audio recording by an Audio Forensics expert can detect tampering of an audio recording, regardless of the capture method and the type of editing that has been performed.

TYPES OF CASES

We perform authentication of audio recordings in all sectors including for use in criminal trials (both Crown and Magistrates), civil trials and family court matters,

As our duty is to the court and not the instructing party we can perform work on the instruction of both prosecution and defence, and can offer rates that meet those of the Legal Aid Agency accordingly.

TYPES OF RECORDINGS

We have experience in the detecting of edits to audio recordings from a wide range of devices, including, but not limited to:

• Mobile phone calls

• Call Centre recordings (for example, from telesales or insurance companies)

• 999 call recordings

• Mobile phone recordings (for example using iPhone Voice Memos)

• Dictaphone recordings

• Portable recorders

• Body Worn Camera recordings

• CCTV camera audio

• Undercover recordings

Types of Manipulations

As we use a variety of techniques, each devised to identify a different trace left by the audio editing process, we can detect a variety of manipulations, including:

• Deleted sections / Removal of sections

• Cloned sections

• Replaced sections

• Trimmed recordings

• Recordings purported to be from a different device
