Abstract
Method of processing an audio signal, audio reproduction system, and processing unit for conditioning audio signals. The audio signal includes at least first and second channels, the first channel being time-delayed by a predetermined delay factor, and a volume level of the first channel being attenuated by a predetermined attenuation factor. This attenuated and time-delayed first channel is added to the second channel to provide a second channel of the audio signal intended for reproduction.
