摘要： The invention relates to a circuit (100) for enhancing a stereo sound signal, represented by a left input signal (L) and a right signal (R). By only using the parts of the left input signal (L) and the right input signal (R) that are not correlated to each other, unwanted stereo enhancement of, for example, dialogs is eliminated. On the other hand, the stereo image of sound effects like explosions will be enhanced. Most movies are properly mixed for this. In one embodiment of the invention, a center signal is generated by averaging the left input signal and the right input signal. The invention relates to a method of enhancing a stereo sound signal. The invention also relates to an apparatus (500) for reproducing sound. The invention further relates to a record carrier (610) comprising a computer-executable code, enabling a computer (620) to perform the method according to the invention

摘要： A multi-channel audio conversion system is described, comprising audio mode converting means having a signal input and a signal output for converting audio input signals to audio output signals representing audio in an audio output mode. The audio mode converting means are arranged for user controlled conversion from the audio input signals to the audio output signals. Advantageously the influencing of the conversion from audio input signals to audio output signals may take place by the listener. This results in a smooth and personalized freedom of choice regarding the amount of multi-channel stereo and/or surround effects in the audio output signals of the system.
