FLAIR: Room Impulse Response Dataset with Laser-Calibrated Room Geometry

The Field LAser-calibrated Impulse Response (FLAIR) dataset contains a total of 270 room impulse responses, along with a millimeter accurate dense 3D point cloud of the room. This dataset provides a basis for investigating inverse spatial audio problems that rely on boundary information, including sound field reconstruction [1] and room impulse response estimation [2]. This dataset was originally published in [1], where detailed descriptions are provided. [1] "Bayesian Sound Field Reconstruction Using Partial Boundary Information", D. Sundström, F. Elvander, and A.
