Abstract
A sound processing system reduces speaker distortion at high volume levels by attenuating the filter gain and/or tone of audio and mixed output signals. The sound processing system has one or more filters to attenuate the filter gain and tone in response to the high volume levels. The sound processing system also can attenuate the filter gain and tone in response to a sound pressure level, which may be provided by a microphone.
