We present a dataset used in the paper “A Closed Form Solution to the Microphone Position Self-Calibration Problem” (ICASSP 2012) for the calibration of microphone and sound source events position. The dataset contains the time of arrival of the sound events, the final calibration results and the ground truth obtained using a VICON motion capture system. For details please check the description in the .zip file and cite the paper if you use the dataset for your experiments.

Dataset description

  • Room of 6 x 4 x 3 meters with 8 microphones and 21 sources obtained by moving a transducer in different positions. Distance is proportional to time of flight.
  • Time of flight of the sound event computed using a chirp signal.
  • Ground truth was measured by a VICON motion capture system.
