Abstract:
An electronic device, method, and computer program product provide acoustic limiting of an audio output using a feed-forward, filter-based, acoustic control system. An audio signal is received that has more than one acoustic frequency spectra intended for conversion to an acoustic output by transducers of an electronic device. A determination is made of an expected acoustic magnitude respectively for each acoustic frequency spectrum of the more than one acoustic frequency spectra. A determination is made whether the expected acoustic magnitude of any acoustic frequency spectra will exceed an acoustic output threshold. The acoustic control system attenuates the first acoustic frequency spectrum to generate a filtered audio signal with an attenuated acoustic frequency spectrum that is less than or equal to the acoustic output threshold. The filtered audio signal is transmitted to the at least one transducer to the produce the audio output that does not exceed.

Claim (Index 13):
A computer program product comprising:\n a non-transitory computer readable storage device; and program code on the computer readable storage device that when executed by a processor associated with an electronic device, the program code enables the electronic device to provide the functionality of:\n receiving an audio signal having more than one acoustic frequency spectra; \n determining an expected acoustic magnitude respectively for each acoustic frequency spectrum of the more than one acoustic frequency spectra; \n determining whether the expected acoustic magnitude of any of the more than one acoustic frequency spectra will exceed an acoustic output threshold resulting in a filtered audio signal; \n in response to determining that a first acoustic frequency spectrum of the more than one acoustic frequency spectra will exceed the acoustic output threshold, attenuating the first acoustic frequency spectrum to generate a filtered audio signal with an attenuated acoustic frequency spectrum that is less than or equal to the acoustic output threshold; \n determining whether the first acoustic frequency spectrum of the more than one acoustic frequency spectra will be less than the acoustic output threshold by a headroom value; \n in response to determining that the first acoustic frequency spectrum of the more than one acoustic frequency spectra will be less than the acoustic output threshold by the headroom value, amplifying the first acoustic frequency spectrum to reduce a headroom of the first acoustic frequency spectrum in the filtered audio signal; and \n transmitting the filtered audio signal to the at least one transducer of the electronic device.
