13. A transducer driving system, comprising:
a driver output for driving an amplifier that drives an electromagnetic load;
a feedback input for receiving a signal driven by the amplifier in order to control a feedback loop of the transducer driving system; and
an unexpected spectral content detector and controller subsystem configured to:
detect unexpected spectral content in the signal;
declare an indicator event based on the detected unexpected spectral content;
determine whether the indicator event occurs in an undesired pattern; and
in response to the indicator event occurring in the undesired pattern, modify a behavior of the transducer driving system.
