Considering that people watch video clips often on mobile terminals, we propose a method for surround sound mixing. In this method, a binaural signal for headphone listening is first generated and then decomposed into a surround sound signal such that the simple mixing of the surround sound signal into stereo results in the desired binaural signal. In order to make it also available for loudspeaker listening, a constrained weighted least squares problem is solved, where the constraint is that the previously mentioned condition is satisfied and the weight is the inverse of the power of each surround sound signal for the given frequency and time frame. The error function is the difference between the original surround sound signal and that obtained by decomposing the binaural signal. |
