Abstract:
A system includes a filter circuit configured to adjust digitized audio signal values based on filter parameters. The system also includes a filter parameter selection circuit configured to determine an audio signal bandwidth estimate based on back-EMF analysis and to supply different sets of filter parameters to the filter circuit based on the audio signal bandwidth estimate and a predetermined threshold. The system also includes a digital-to-analog converter (DAC) configured to convert an output of the filter circuit into an analog audio signal to be amplified.

Claim (Index 20):
The method of  claim 19 , further comprising:\n obtaining the voltage measurements and the current measurements from a voltage/current sensor as a function of time; estimating resistance values for the voice coil of the speaker as a function of time; and performing adaptive speaker parameter estimation based on the voltage measurements, the current measurements, and the estimated resistance values, wherein the different sets of filter parameters are obtained from adaptive speaker parameter estimation operations.
