Abstract
In accordance with some embodiments of the present invention there is provided a system, a method and a circuit for processing a stereo audio signal. According to some embodiments, the system for processing a stereo audio signal may include an audio processing circuit. The audio processing module or circuit may be operatively connected to an audio input interface and to an output audio interface. Through the audio input interface, the audio processing circuit may be adapted for receiving a 2-channels stereo audio signal. The audio processing module may be adapted for determining an output mono audio signal representing the center sound and a stereo audio signal representing the stereo sound without the center. Through the output interface the audio processing circuit may provide each of an output mono audio signal representing the center sound and a stereo audio signal representing the stereo sound without the center.
