Abstract

Method for optimizing an audio signal in which the difference between a predefined audio signal and a modified signal that results from the predefined audio signal is continually determined. The signal difference is continuously determined in the time and or the frequency domain to provide an optimized audio signal. An Independent claim is made for a device for optimizing an audio signal with an arrangement for continuously determining the difference between a predefined audio signal and a modified audio signal derived from it and an arrangement for continuously determining an optimum audio signal based on the determined difference, whereby the difference is determined in the time or frequency domain.
