Forensic Audio Analysis

Document Thumbnail

[Feature] Forensic audio analysis now involves the use and analysis of digital techniques and signals in order to support criminal investigations. Tasks such as the detection of edits or the use of data compression can be made easier using sophisticated statistical analysis of audio samples. Voices may be disguised either intentionally or otherwise, and audio signal processing can be used either to simplify the segmentation of recordings into different talkers or to evaluate the effects of voice processing. There is also the question of evaluating the quality or intelligibility of signals that have been subject to heavy degradation, where traditional quality prediction algorithms may not work satisfactorily.
