SynIR dataset is a large set of synthetic impulse responses (IR), generated using geometric sound propagation in various room environment. We use 3D house models from the SUNCG dataset. As in the following image, several collision-free far-field sound source-listener pairs (shown as floating colored spheres) are sampled in each one-story house, and each pair's corresponding IR up to 8kHz is computed using geometric propagation.
This dataset is under heavy development, so please stay tuned.
Agreement of SynIR dataset
Before we are able to offer you access to SynIR dataset (the Dataset), please read the following aggrement and indicate your response.
This dataset has several versions synthesized for different microphone specifications. Detailed channel layouts and the naming scheme of wavfiles will be given soon, or upon request. Each dataset contains about 10K multi-channel wavfiles. The corresponding statistic files contain the RT60 and Speech Transmission Index (STI) of each file averaged over channels.Download SynIR 6-channel version (8GB) md5: 37aabca7ee22b8ebe4b4fd3bb55cfdf2
