Patent ID: 7343019

Claim:
A method of normalization for streaming digital signals, comprising: (a) inputting a stream of digital signals into a playout buffer; (b) finding a current normalization gain for a current output digital signal from said playout buffer by the steps of: (i) finding the maximum digital signal magnitude of the digital signals in a sequence of digital signals in said playout buffer with said sequence including said current output digital signal where said current output digital signal precedes in said stream all other digital signals in said sequence, (ii) finding a gain factor for said current output digital signal using said maximum digital signal magnitude from (i), (iii) combining said gain factor from (ii) with a prior normalization gain for a prior output digital signal from said playout buffer when said gain factor is greater than said prior normalization gain, where said prior output digital signal precedes said current output digital signal in said stream; (c) outputting said current output digital signal from said playout buffer and modifying said current output digital signal with said normalization; (d) repeating steps (b) and (c) for a digital signal following said current output digital signal in said stream.
