Abstract
A method for processing audio signal that includes receiving a plurality of digital audio signals and calculating signal levels of them. The next step is calculating smooth attenuation signal for each one of the input audio signals. The smooth attenuation signals are calculated according to the signal levels and smoothing criteria, such that the mixing of signals that include the input audio signals multiplied by their respective smooth attenuation signals is peak limited by a given threshold level.
