Your case is based upon audio which you believe has been tampered with. However, you need an expert to analyze and detect these edits and redactions to help prove this.
Creative Forensic Services provides authentication and tampering analysis for the detection of editing or redaction of recorded audio and video evidence. Forensic Audio Authentication is the process of qualifying the validity or authenticity of an audio recording.
Often times a dispute will arise regarding the admissibility of recorded evidence.
For example, a person being charged with a criminal act based upon a prior confession, might question if the recording had been redacted, edited or tampered with in some way. This is one reason why someone might question the authenticity of an audio or video recording.
