Predictive Automatic Gain Control In A Media Processing System
A method and a media processing system (MPS) for automatic gain control are provided. The MPS detects a portion of an input signal corresponding to a measurement window associated with a predetermined time interval and determines a peak value of the input signal during a first predetermined time segment within the measurement window. The MPS determines a number of occurrences of the peak value during a second predetermined time segment within the measurement window and compares the determined number of occurrences of the peak value with a predefined range of occurrences for identifying a speech portion or a non-speech portion of the input signal corresponding to the measurement window. The MPS adjusts a gain corresponding to the first predetermined time segment based on the peak value, upon identifying the speech portion. The MPS iteratively performs the method by shifting the measurement window in steps of the first predetermined time segment.
