Abstract:
1. A method comprising: processing an audio signal with an audio system to identify a first audio source; determining whether the audio system stores an association between the first audio source and a gain; when the audio system does not store the association between the first audio source and the gain, modifying an automatic gain control algorithm with the audio system to increase at least one of an attack or decay rate, and applying the modified automatic gain control algorithm to the audio signal to determine the gain for the first audio source; applying, with the audio system, the gain for the first audio source to a representation of the audio signal to produce an output audio signal; after applying the gain to the representation of the audio signal, restoring the automatic gain control algorithm with the audio system to reduce at least one of the attack or decay rate; applying, with the audio system, the restored automatic gain control algorithm to the representation of the audio signal to determine a resultant gain for the first audio source; associating a first voice print with the resultant gain; storing the association of the first voice print with the resultant gain to a storage medium as the association between the first audio source and the resultant gain; and outputting the output audio signal from the audio system.
