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本数据集包含三维房间冲激响应（3D room impulse responses），其采集时采样频率为16 kHz，网格测点间距为2 cm（每个扬声器对应48×51×26个网格点）。完成测量后，我们抑制了麦克风阵列框架产生的反射信号，并将所有冲激响应截断至0.25秒时长。 附带提供MATLAB示例代码（example_read_visualization.m）作为附加文件。 针对Python使用者，需注意：由于本数据集由MATLAB生成，而MATLAB与NumPy采用不同的数组排序约定，因此使用Python/NumPy加载该数据集时，HDF5数组的维度可能会出现转置。用于加载并重塑该数据集的Python示例代码可在数据集GitHub页面获取：https://yh-audio.github.io/meshgrid-ir.html 本项目同步发布了配套数据集（第0部分），该数据集包含采样频率为48 kHz的房间冲激响应，且未移除测量系统引入的人工反射信号，单条信号时长为100 ms。 本数据集的DOI为：https://doi.org/10.5281/zenodo.19656813 如需了解更多细节，请参阅三维冲激响应数据集页面：https://yh-audio.github.io/meshgrid-ir.html
