Name That Room: Room Identification Using Acoustic Features in a Recording
This paper presents a system for identifying the room in an audio or video recording through the analysis of acoustical properties. The room identification system was tested using a corpus of 13440 reverberant audio samples. With no common content between the training and testing data, an accuracy of 61% for musical signals and 85% for speech signals was achieved. This approach could be applied in a variety of scenarios where knowledge about the acoustical environment is desired, such as location estimation, music recommendation, or emergency response systems.
Biography
Nils Peters is a postdoctoral fellow at the International Computer Science Institute (ICSI) and the Center for New Music and Audio Technologies (CNMAT) at UC Berkeley, California. He holds a MSc degree in Electrical and Audio Engineering from the University of Technology in Graz, Austria, in 2005 and a PhD in Music Technology from McGill University in Montreal, Canada, in 2011. Besides being a core developer of the media processing library Jamoma, he works on real-time algorithms for sound-field analysis using microphone arrays. Nils also organizes UC Berkeley’s lecture series on spatial audio technology and room acoustics.
