A method and system for the configuration of a mobile station baseband
circuit for an acoustic accessory having an identifier, the method
comprising the steps of: determining whether the mobile device recognizes
the identifier of the acoustic device; and configuring the baseband
circuit with a DSP filter response and CODEC acoustic gain parameters for
the acoustic device if the mobile device recognizes the identifier of the
acoustic device. The system comprising: an identifier for each of the
plurality of acoustic devices; a local memory in the mobile station
storing a frequency (filter) response and gain parameters for at least
one of the plurality of acoustic devices and for mapping them to the
identifier; and a digital signal processor to re-shape an acoustic
frequency response and adjust an audio gain of a baseband circuit for the
mobile station based on the stored frequency response and gain
parameters.
