Abstract
We introduce a database of multi-channel recordings performed in an acoustic lab with adjustable reverberation time. The recordings provide detailed information about room acoustics for positions of a source within a confined area. In particular, the main positions correspond to 4104 vertices of a cube-shaped dense grid within a 46 × 36 × 32 cm volume. The database can serve for simulations of a real-world situations and as a tool for detailed analyses of beampatterns of spatial processing methods. It could be used also for training and testing of mathematical models of the acoustic field.
