- Description
- A man’s alibi to his girlfriend’s murder centres on a mysterious phone call. Police enquiries locate a public phone box in a sleepy village and a subsequent search reveals a broken cassette tape in a roadside ditch. Peter French was called in to analyse the tape and unlock its secrets. He found that the signal characteristics recorded onto the tape matched those of a tape recorder belonging to the suspect. Further checks were carried out on a batch of the same model of recorder as a control. None of the results matched the original fragment of tape. The man was charged and convicted. audio tape analysis Police enquiries signal-characteristics
