MIRaGe: Multichannel Database Of Room Impulse Responses Measured On High-Resolution Cube-Shaped Grid In Multiple Acoustic Conditions
This database addresses the need for high-resolution acoustic data for researchers in audio processing and spatial audio, though it is incremental as it focuses on data collection rather than new methods.
The authors introduced a multichannel database of room impulse responses measured on a high-resolution cube-shaped grid under adjustable acoustic conditions, providing a tool for detailed analysis of spatial processing methods and training/testing of acoustic field models.
We introduce a database of multi-channel recordings performed in an acoustic lab with adjustable reverberation time. The recordings provide information about room impulse responses (RIR) for various positions of a loudspeaker. In particular, the main positions correspond to 4104 vertices of a cube-shaped dense grid within a 46x36x32 cm volume. The database thus provides a tool for detailed analyses of beampatterns of spatial processing methods as well as for training and testing of mathematical models of the acoustic field.
