Multichannel Impulse Response Database

The Multichannel Impulse Response Database is a joint venture between the Institute of Communication Systems and Data Processing, RWTH Aachen University, Germany and the acoustic lab at BIU. The impulse responses were measured at BIU acoustic lab, characterized by configurable reverberation level. The database consists of  three different acoustic scenarios with reverberation times RT60 equals to 160 ms, 360 ms and 610 ms. The measurements were carried out in recording sessions of several source positions on a spatial grid (angle range of 90° to 90° in 15° steps with 1 m and 2 m distance from the microphone array). The signals in all sessions were captured by three microphone array configurations. The database is accompanied with software utilities to easily access and manipulate the data.
