Method and mobile communication device for characterizing an audio accessory for use with the mobile communication device
First Claim
1. A method for characterizing an audio accessory for use with a mobile communication device, the mobile communication device comprising a microphone having a microphone spectral response, the microphone spectral response stored in a memory of the mobile communication device, the method performed by the mobile communication device and comprising:
- detecting attachment of an audio accessory to the mobile communication device;
prompting a user of the mobile communication device to initiate testing of the audio accessory;
playing an audio test regimen over the audio accessory;
measuring audio parameters with the microphone while playing the audio test regimen;
processing the audio parameters in view of the microphone spectral response to provide an audio accessory spectral response.

Abstract
A mobile communication device (100) is attached to an audio accessory (114, 124) and characterizes the audio response of the audio accessory. Upon detecting attachment to the mobile communication device (204), the mobile communication device plays an audio test regimen over the speaker of the audio accessory (210, 212, 214, 216, 218, 220). Once the audio accessory'"'"'s spectral response is known, the mobile communication device may adjust audio processing filter coefficients used in processing audio signals played over the audio accessory.
