Abstract
A sound pickup system with which there are associated a video aiming system and a method for the setting of the characteristic parameters of the sound pickup. The device comprises, in addition to the network of sensors, a control unit and a circuit for the setting of the characteristic parameters, a video camera, a video screen and a circuit for coupling the screen to the a circuit for setting the characteristic parameters of each of the sound reception channels in order to achieve a superimposition of images so that it is possible to control the setting of the parameters with respect to the position and size of the sound sources. A method for the setting of the characteristic parameters of the sound pickup enables the interpolation of the coefficients of digital filters linearly and in time. Application to sound pickup systems adapted to conference halls.
