Abstract: It is inter alia disclosed to generate a signal representation at least based on a noise reduced component from a signal and on a noise component from the signal, said signal representation comprising at least two channel representations.

Abstract: A stereophonic signal is converted into a mid channel signal and a side channel signal. Noise is added to the side channel signal. The amount of noise is selected depending on masking thresholds for at least two channels of the stereophonic signal. The mid channel signal and the modified side channel signal are quantized for transmission. Alternatively or in addition, a set of quantization parameter for the quantization of the side channel signal is selected depending on the masking thresholds.

Abstract: A method, apparatus and computer program product are provided to synchronize audio signals with video images that are replayed with a modified motion. In a method, a trajectory is determined for each audio object of an audio signal. The method also determines each of the audio objects to be a transient or non-transient object. The method also causes a respective audio object to be differently extended depending upon whether the audio object is determined to be a transient object or a non-transient object, thereby synchronizing video signals that are to be played back with a predefined motion. The method causes the respective audio object to be differently extended by splitting the transient object into transient segments, inserting silent segments therebetween and maintaining the trajectories of the transient object and/or by repeating the non-transient object with a trajectory that varies based on the predefined motion of the video signals.
