Patent ID: 7363096

Claim:
A system for processing an audio signal to produce an encoded audio signal for subsequent transmission through a selected one of two or more transmission mediums, each of which has one or more transmission medium characteristics, the system comprising: means for receiving signals specifying one of the two or more transmission mediums selected for the subsequent transmission of the encoded audio signal; means for storing processing parameter data related to the two or more transmission mediums, wherein the processing parameter data specifies audio signal processing in two or more cascaded processing stages by which the audio signal is processed according to the one or more of the transmission medium characteristics of the two or more transmission mediums to produce the encoded audio signal for subsequent transmission through the selected one of the two or more transmission mediums; means for retrieving from the memory, the processing parameter data corresponding to the transmission medium selected for the transmission of the encoded audio signal; and means for processing the audio signal in the two or more cascaded processing stages in accordance with the retrieved processing parameter data to produce the encoded audio signal for subsequent transmission through the selected one of the two or more transmission mediums, wherein the two or more cascaded processing stages includes a sample rate converter stage.
