Abstract

We report on a recently-recorded database for use in processing of ad hoc microphone constellations. Twenty-four microphones were positioned in various locations at a central table in a large room, and their outputs were recorded while 4 target talkers at the table both read from a list of sentences in a constrained way and also maintained a natural conversation for several minutes. This was done in the quiet and in the presence of 8, 24, and 56 other simultaneous talkers surrounding the central table at various distances. We also recorded without the 4 target talkers active in each of these conditions, and used a loudspeaker to measure impulse responses to the microphones from various positions in the room. We provide details of the recording setup and demonstrate use of this database via an application of linearly constrained minimum variance beam-forming. The database will become available to researchers in the field.
