Abstract:
Techniques for processing input signals in accordance with an output configuration are disclosed. According to one aspect of the techniques, a module implemented in a sound reproducing device is configured to determine whether a sound in the input audio source can be reproduced properly through speakers of an output configuration of the device by examining the sound effects in the input audio sound and the output channel in the output configuration, producing synthetically a sound effect if the number of sound channels is greater than the number of sound effects, or reducing synthetically a sound effect if the number of sound channels is less than the number of sound effects.
