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)

Deleted sections / Removal of sections
Recordings purported to be from a different device
Our Audio Forensics expertise is evidenced by our peer-reviewed and published scientific research papers, presentations at international conferences and degrees in both Audio Engineering and Media Forensics.
