Abstract
Audio signals are processed in a manner that facilitates control for overpower conditions. According to an example embodiment of the present invention, an audio processing circuit is configured and arranged for controlling an output audio signal as a function of an output power and/or clip condition. The audio processing circuit is adapted to approximate output power from an amplifier independent from output load and varying line conditions. When an overpower and/or clip condition is approximated, a signal is generated to reduce the output power by, e.g., reducing the signal gain and/or disconnecting the output.
