Speech enhancement has come a long way in the digital era, but it is not the ‘magic wand’ depicted on TV and in Hollywood movies. Adaptive filters have traditionally been the basis of forensic audio work, but a combination of techniques – including broadband noise reduction, buzz removal, equalisation and background noise suppression – can provide superior results when compared with any single approach. This introduction, illustrated using examples processed in real-time on a CEDAR Cambridge Forensic system, aims to shed light on this, demonstrating how signal processing can aid investigators in areas including criminal investigation, counter-terrorism and air accident investigation.
