Introduction to Audio Analysis - Theodoros Giannakopoulos

. .

Résumé :
Introduction to Audio Analysis serves as a standalone introduction to audio analysis, providing theoretical background to many state-of-the-art techniques. It covers the essential theory necessary to develop audio engineering applications, but also uses programming techniques, notably MATLAB?, to take a more applied approach to the topic. Basic theory and reproducible experiments are combined to demonstrate theoretical concepts from a practical point of view and provide a solid foundation in the field of audio analysis.

Audio feature extraction, audio classification, audio segmentation, audio coding and music information retrieval are all addressed in detail, along with material on basic audio processing, frequency domain representations and filtering, and introductory psychoacoustics. Throughout the text, reproducible MATLAB? examples are accompanied by theoretical descriptions, illustrating how concepts and equations can be applied to the development of audio analysis systems and components. A blend of reproducible MATLAB? code and essential theory provides enable the reader to delve into the world of audio signals and develop real-world audio applications in various domains.

Biographie:
Forensic scientists are responsible for analyzing evidence collected at crime scenes and providing expert testimony related to the evidence during trials. While some forensic scientists do go out in the field to collect evidence, this is a job that is usually done by forensic or crime scene investigative technicians. Forensic scientists work closely with police and other law enforcement agencies in order to determine how and why a criminal act was perpetrated and to find the guilty person.

The aim of this book is to review the United State's Federal Rules of Evidence, regarding expert testimony and will include a multi-disciplinary look at the strengths and weaknesses in forensic science courtroom testimony. The statutes and the effects of judicial uses or non-use of the FRE, Daubert, Kumho, and the 2009 NAS report on Forensic Science will be included. The presentation will expand to study case law, legal opinions and studies on the reliability and pitfalls of forensic expertise in the US court system. Forensic Science Testimony will be useful in preparation for courtroom testimony, as well as classroom instruction.
