Patent ID: 7257452

Claim:
A graphical user interface for facilitating processing of a source audio signal by an audio signal processor to produce an encoded audio signal for subsequent transmission of the encoded audio signal through one of a plurality of transmission mediums selected for the transmission of the encoded audio signal, each of the plurality of transmission mediums having one or more transmission medium characteristics, the graphical user interface comprising a menu for displaying user selectable menu elements corresponding to a plurality of audio processing profiles related to the plurality of transmission mediums, the graphical user interface operable for: receiving user input data specifying a transmission medium selected for the transmission of the encoded audio signal; communicating the user input data specifying the transmission medium to the audio signal processor; receiving an encoded audio signal from the audio signal processor, wherein the encoded audio signal is generated at least in part by processing the source audio signal in two or more cascaded processing stages according to a audio processing profile comprising one or more processing parameters based at least in part on the one or more transmission medium characteristics of the transmission medium selected for the transmission of the encoded audio signal; displaying a visual representation of the source audio signal besides a visual representation of the encoded audio signal in a manner allowing for a visual comparison of the source audio signal and the encoded audio signal; and displaying an audio profile editing screen in response to a user selection of at least one of the user selectable menu elements corresponding to the plurality of audio processing profiles.
