SpaDenRIR - Spatially Dense simulated Room Impulse Responses

SpaDenRIR is a a simulated dataset of Spatially Dense Room Impulse Responses designed for developing and benchmarking sound-field reconstruction methods for early reflections. The dataset comprises 100 simulated, non-rectangular rooms, each containing a cubic microphone array of 22×22×22 microphones with 21.4 mm spacing, allowing spatial interpolation without aliasing up to 8 kHz. In every room, five sources are placed in distinct regions relative to the array. Room impulse responses are simulated using the image-source method and stored only for the first 100 mS, capturing the direct sound and early reflections.
