Abstract
This document discusses, among other things, apparatus and methods for providing audio transducer protection. In an example, an audio protection circuit can include a first comparator configured to compare peak power information of a drive signal of an amplifier of an audio system with a first threshold, a limiter circuit configured to limit an input of the amplifier if the peak power information of the drive signal exceeds the first threshold, and a second comparator configured to compare average power information of the drive signal with a second threshold and to provide an output signal configured to modulate a gain of a pre-amplifier of the audio system using the comparison.
