3D Meshgrid Room Impulse Response Dataset (part I)

The dataset contains 3D room impulse responses measured at a sampling frequency of 16 kHz with 2 cm spacing (48 × 51 × 26 grid points per loudspeaker). After measurement, reflections from the microphone array frame were suppressed and the impulse responses have been truncated to 0.25s. MATLAB example code (example_read_visualization.m) is included as an additional file. For Python users, please note that the dimensions of the HDF5 arrays may appear transposed when loaded with Python/NumPy, because the dataset was generated using MATLAB and MATLAB and NumPy use different array ordering conventions. A Python example code for loading and reshaping the dataset is available on the GitHub dataset page: https://yh-audio.github.io/meshgrid-ir.html We additionally release a complementary dataset (Part 0), which contains room impulse responses sampled at 48 kHz before the removal of artificial reflections from the measurement system, with a duration of 100 ms. https://doi.org/10.5281/zenodo.19656813 For details, please refer to the 3D IR dataset page: https://yh-audio.github.io/meshgrid-ir.html
