Patent ID: 7149593

Claim:
A method for processing a source audio file to produce an encoded audio file, the encoded audio file corresponding in audio content to a portion of audio content of the source audio file for subsequent transmission through one of two or more transmission mediums selected for the transmission of the encoded audio file, each of the two or more transmission mediums having one or more transmission medium characteristics, the method comprising: storing an audio processing profile corresponding to each of the two or more transmission mediums, wherein the audio processing profile comprises processing parameter data for processing the source audio file in two or more cascaded processing stages, wherein the processing parameter data is based on the one or more of the transmission medium characteristics of the transmission mediums; associating data specifying the portion of the audio content of the source audio file to be encoded with at least some of the audio processing profiles corresponding to each of the two or more transmission mediums; receiving signals which specify one of the two or more transmission mediums selected for the transmission of the encoded audio file; retrieving the processing parameter data corresponding to the transmission medium selected for the transmission of the encoded audio file; and processing the specified portion of the audio content of the source audio file in the two or more cascaded processing stages in accordance with the retrieved processing parameter data to produce the encoded audio file for subsequent transmission through the transmission medium selected for the transmission of the encoded audio file.
