Abstract
The bandwidth of a codec is compared with a determined bandwidth of the output signal produced by the codec. If the bandwidths match, then an audio profile of the apparatus is set to correspond to the established bandwidths and a corresponding icon is rendered on a display of the apparatus. If the signal bandwidth is narrower, than the codec bandwidth, then the audio profile of the apparatus is set to a narrower audio profile and a corresponding icon is rendered on the display of the apparatus. The bandwidth of the signal processed by the codec may be determined in several different ways and the narrower audio profile includes reduced bandwidth, reduced gain, or reduced dynamic range.
