Audio forensics as the field of forensic science relating to the acquisition, analysis, and evaluation of sound recordings that may ultimately be presented as admissible evidence in a court of law or some other official venue.
Audio forensic evidence may come from a criminal investigation by law enforcement or as part of an official inquiry into an accident, fraud, accusation of slander, or some other civil incident. Experts use different software in audio and video enhancement software to analyse the data.

The primary aspects of audio forensics are establishing the authenticity of audio evidence, performing enhancement of audio recordings to improve speech intelligibility and the audibility of low-level sounds, and interpreting and documenting sonic evidence, such as identifying talkers, transcribing dialogue, and reconstructing crime or accident scenes and timelines.
Modern audio forensics makes extensive use of digital signal processing, with the former use of analogue filters now being obsolete. Techniques such as adaptive filtering and discrete Fourier transforms are used extensively.
