Forensic Audio Analysis

Audio forensics (as opposed to Forensic Acoustic Analysis) concerns the investigation of sound recorded or transmitted by electronic means, to help our clients find the answer to their audio enigmas. Recent projects include analysis of telephone recordings to determine whether answers to pre-recorded messages were genuine, or whether calls have been duplicated. For Sky News, we dissected the audio that was broadcasted during a Russian news programme, looking for evidence, such as data discontinuities, artefacts or unusual spectral distribution, of whether the phone call that formed the subject of the show was genuine, or otherwise.
