This book provides an expert introduction to audio forensics  an essential specialty in modern
forensic science  equipping readers with the fundamental background necessary to understand and
participate in this exciting and important field of study. Modern audio forensic analysis
combines skills in digital signal processing  the physics of sound propagation  acoustical
phonetics  audio engineering  and many other fields. Scientists and engineers who work in the
field of audio forensics are called upon to address issues of authenticity  quality enhancement
and signal interpretation for audio evidence that is important to a criminal law enforcement
investigation  an accident investigation board  or an official civil inquiry.Expertise in audio
forensics has never been more important. In addition to routine recordings from emergency call

now in widespread use. Forensic evidence from the scene of a civil or criminal incident
increasingly involves dashboard recorders in police cars  vest-pocket personal recorders worn
by law enforcement officers  smart phone recordings from bystanders  and security surveillance
systems in public areas and businesses. Utilizing new research findings and both historical and
contemporary casework examples  this book blends audio forensic theory and practice in an
informative and readable manner suitable for any scientifically-literate reader. Extensive
