Method and system for the configuration of a mobile station baseband circuit for an acoustic accessory |
摘要 |
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.
