MUltimicrophone source localization data base (MUSLOD)

The MUSLOD (Multi-microphone Source LOcalisation Data base) data base presented in this document is the result of work carried out in the center of development of advanced technologies in collaboration with the laboratory of (communication parlée) at USTHB. The database thus obtained contains 63,360 seconds (18 hours). Inspired from existing databases of specialized community, we propose a platform for sound acquisition using four microphones in order to develop a database called MUSLOD. It will be used for localization of sound sources in reverberant environments. We present the experimental device used for the development of basic MUSLOD data and place of registration and the terms of implementation. It consists of actual data desktop environment from a network of linear microphones. For this, we use different values of sampling and different inter-microphone distances frequencies, location data are presented for different emission angles of the sound source. The database is divided into two broad categories registration: The first category contains records acquired but denoised by a method of spectral subtraction. The second category contains rough recordings. The sampling frequencies used are 8, 16, 44.1, and 64 KHz.
