Structure from Sound Database (sfsdb)
This is a database of 'structure from sound' experiments. In each experiment multiple (typically 8-12) stationary microphones record the sound from a single moving sound source.
The task is to find the position of both the microphones and the moving sound source just from the sound recorded by the microphones.

Description of Data
The data is structured as ./Measurement Campaign/experiment/, Then each experiment folder contains the files:
- Track i.wav , the recording of the i-th microphone
- info.json , information about the experiment
and if ground truth is available, the experiment folder also contains
- gt_positions.csv , the ground truth positions of microphones and sound source.
- gt_tdoa.csv , the ground truth TDOA (could also be computed from gt_positions.csv)
