This paper presents a novel application for capturing the sound of the action during a football match by automatically mixing the signals of several microphones placed around the pitch and selecting only those microphones which are close to, or aiming at, the action. The sound engineer is presented with a user interface where he or she can define and move dynamically the point of interest on a screen representing the pitch, while the application controls the faders of the broadcast console. The technology has been applied in the context of a three-dimensional surround sound playback of a Spanish first-division match.
