In this paper we describe a new multichannel room impulse responses database. The impulse responses are measured in a room with configurable reverberation level resulting in 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. Besides the description of the database we demonstrate its use in spatial source separation task.
