Forensic audio enhancement is the process of clarifying audio recordings to increase intelligibility. Processing techniques must be applied to unwanted noises like static, HVAC fans, hums and other distracting sounds first. These distracting noises are also known as “unwanted sounds”. Once these sounds have been reduced or removed, then processing techniques can be applied to increase the “desired sounds”.

Often times when a lay person processes an audio recording, these changes can effect a negative effect. The authenticity of the events change, and inaccurate representation of the events makes the recording inadmissible in court.

A qualified forensic expert must perform the? audio enhancement or audio restoration, document the procedures used, and present their findings to a trier of fact.
