Abstract
Disclosed are systems and methods for generating a long-term signal level estimate during automatic gain control. In an example method, a computing device receives an input signal comprising feed data, the input signal derived from an upstream input signal. The computing device selects a first subset of the feed data and divides the first subset of the feed data into a plurality of analysis intervals. The computing device calculates a statistical average of each analysis interval and generates a first Gaussian distribution based on the statistical average of each analysis interval of the plurality of analysis intervals. Based on one or more characteristics of the first Gaussian distribution, the computing device determines the long-term signal level estimate, generates a first stage gain based on the long-term signal level estimate, and applies the first stage gain to the input signal.
