3 : Sound-Source Localization
Descriptif
During the third part, we will study Sound-Source Localization: time difference of arrival (TDOA), estimation of TDOA by cross-correlation, in the temporal and spectral domains, the geometry of multiple microphones, embedding the microphones in a robot head, predicting direction of a sound with a robot head and an example of sound direction estimation.
