Abstract:
1. An adaptive gain control method for digital audio samples, the method comprising: initializing processing of a media stream; adjusting gain of a first set of digital audio samples in the media stream using a fast gain adaptation scheme, resulting in a first group of gain-adjusted digital audio samples having normalized volume during presentation; transmitting the first group of gain-adjusted digital audio samples to a remotely-located media player to generate sound based on the first group of gain-adjusted digital audio samples; thereafter, adjusting gain of a second set of digital audio samples in the media stream using a steady state gain adaptation scheme that is different than the fast gain adaptation scheme, resulting in a second group of gain-adjusted digital audio samples having normalized volume during presentation, wherein the second set of digital audio samples follow the first set of digital audio samples, and wherein the second group of gain-adjusted digital audio samples follow the first group of gain-adjusted digital audio samples; and transmitting the second group of gain-adjusted digital audio samples to the remotely-located media player to generate sound based on the second group of gain-adjusted digital audio samples.
