ABSTRACT:
An automatic gain control method in accordance with the inventive arrangements can include the following steps. Initially, an audio signal can be provided to an audio device which has a range of permissible signal level settings and a signal level controller for establishing a particular signal level setting. In addition, an actual signal level can be measured for the audio signal at an established signal level setting. The measured actual signal level further can be stored in a volume map along with the corresponding established signal level setting. Following the storage of the measured actual signal level in the volume map, a different signal level setting can be established using the signal level controller. Subsequently, the actual signal level can be re-measured and the re-measured actual signal level and corresponding established different signal level setting can be stored in the volume map. Finally, the volume map can be used during an audio processing session to determine a signal level setting for the audio device, wherein the signal level setting corresponds to a desired actual audio signal level. In one aspect of the present invention, the method can also include detecting a hysteresis condition in the volume map.
