METHOD AND DEVICE FOR CONTROLLING A REPRODUCTION UNIT USING A MULTI-CHANNEL SIGNAL

摘要

The method involves determining a characteristic of a set of restoration (2) of acoustic field at a spatial field. A parameter representing a position of a restoration unit (3n) is determined in a three dimensional space with respect to a given point (5). An adaptation filter (A) is determined according to the characteristic and directions of fixed restoration associated with entry signals, for determining a control signal of the unit. The control signal is delivered with respect to an application of the restoration units. Independent claims are also included for the following: (a) a memory medium containing a computer program comprising instructions for executing a method of controlling restoration of acoustic field (b) a device for controlling a set of restoration of an acoustic field.
