Abstract:
A method for processing a virtual acoustic environment that comprises surfaces, using a transmitting device, a receiving device, and a number of filters, comprising the steps of:generating, in the transmitting device, a certain virtual acoustic environment with surfaces which are represented by filters having an effect on an acoustic signal, which effect depends on certain parameters that relate to a transfer function of each filter, so that each of said filters is associated with one of the surfaces of the virtual acoustic environment for describing the effect of such surface in the virtual acoustic environment with its associated filter, transferring from the transmitting device to the receiving device information about said certain parameters relating to the filters, and creating, in order to reconstruct the virtual acoustic environment, a filter bank in the receiving device comprising filters which have an effect on the acoustic signal depending on the parameters relating to each filter and generating the parameters relating to each filter on the basis of the information transferred from the transmitting device.
