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 centers and police radio dispatchers, inexpensive portable audio/video recording systems are 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 examples, supplementary material, and authoritative references are also included for those who are interested in delving deeper into the field. 546 $a Text in English. 650 0 $a Forensic sciences. 650 0 $a Signal processing $x Digital techniques. 650 0 $a Computer sound processing. 650 0 $a Sound $x Digital techniques. $x Digital techniques. 650 7 $a Computer sound processing. $2 fast $0 (OCoLC)fst00872627 650 7 $a Forensic sciences. $2 fast $0 (OCoLC)fst00932011 650 7 $a Signal processing $x Digital techniques. $2 fast $0 (OCoLC)fst01118285 650 7 $a Sound $x Digital techniques. $x Digital techniques. $2 fast $0 (OCoLC)fst01126959 830 0 $a Modern acoustics and signal processing. 941 $a 1 952 $l OVUX522 $d 20200318012631.0 956 $a http://locator.silo.lib.ia.us/search.cgi?index_0=id&term_0=58F4AFB60B6411EAA467CE0D97128E48Initiate Another SILO Locator Search
