Court-ready analysis of digital audio, delivered in accordance with forensic standards.
What is audio forensics?
Forensic audio analysis involves the scientific examination, clarification and interpretation of audio recordings for use in legal proceedings.
This may include enhancement, authentication, speaker comparison and the assessment of recording quality, continuity and evidential integrity.
When a recording is unclear and speech needs to be enhanced or clarified
When there are concerns that an audio file may have been edited, tampered with, or manipulated
When key events or conversations within a recording need to be accurately interpreted
When a reliable transcript of a poor-quality recording is required
When audio evidence is being prepared for use in legal proceedings
When the continuity or integrity of a recording needs to be assessed
When recordings form part of criminal, civil, or regulatory investigations

Our approach
We adopt a structured and methodical approach to the forensic analysis of audio recordings, ensuring that all work is conducted in a transparent, reproducible, and evidentially robust manner.
Audio recordings are first assessed to determine their suitability for analysis and to identify the most appropriate techniques. Enhancement and analytical processes are then applied using validated methodologies, with care taken to preserve the integrity of the original material at all times.
All stages of the examination are documented, including the techniques used and any limitations identified. This ensures that our findings can be clearly explained, independently reviewed, and relied upon within legal proceedings.
The results of the analysis are presented in a clear, balanced, and structured report suitable for use by solicitors, courts, and other decision-makers.
Accreditation and forensic compliance
Our laboratory is accredited by UKAS to ISO/IEC 17025 for specific testing activities.
For forensic casework, we operate in accordance with the Codes of Practice issued by the Forensic Science Regulator, ensuring that all work is suitable for use within the criminal justice system.
Limitations
The extent to which audio recordings can be enhanced or analysed is dependent on the quality and characteristics of the original material.
Poor recording quality may limit the level of improvement achievable
Background noise, distortion, or compression may obscure important details
Severely degraded or incomplete recordings may not contain recoverable information
Enhancement processes cannot recover information that is not present in the original recording
Findings are provided within the context of the available material and any identified limitations
All limitations are clearly documented within our reports to ensure that the findings can be properly understood and appropriately interpreted within a legal context.
Expertise
Our expertise in forensic audio is supported by published research, presentations at international conferences, and advanced academic qualifications, including a 1st Class Honours degree in Audio Engineering and a Master’s degree in Media Forensics.
All experts have undertaken formal training in report writing and courtroom presentation, ensuring that both written and oral evidence is delivered in a clear, structured, and professional manner appropriate to the legal context in which it is used.
