Acoustic Environment Identification and Its Applications to Audio Forensics
IEEE Transactions on Information Forensics and Security, 2013 An audio recording is subject to a number of possible distortions and artifacts. Consider, for example, artifacts due to acoustic reverberation and background noise. The acoustic reverberation depends on the shape and the composition of a room, and it causes temporal and spectral smearing of the recorded sound.

Roomprints for forensic audio applications [PDF]
2013 IEEE Workshop on Applications of Signal Processing to Audio and Acoustics, 2013 A roomprint is a quantifiable description of an acoustic environment which can be measured under controlled conditions and estimated from a monophonic recording made in that space. We here identify the properties required of a roomprint in forensic audio applications and review the observable characteristics of a room that, when extracted from ...
