ABSTRACT:
In one embodiment, a system comprises means for processing multiple result buffers by receiving multiple digital audio signals, providing portions of each of the digital audio signals into individual multi-bit input buffers, and combining the contents of the input buffers in a result buffer to provide a mixed audio signal; means for calculating a volume ramp function for a current result buffer as a function of one or more volumes associated with multiple previously-processed result buffers; means for combining multiple digital audio signals; means for processing the combined digital audio signals with the volume ramp function to provide a processed result signal; and means for providing at least some bits from the processed result signal into a result buffer to provide a mixed audio signal.
