Claim:
1. A method to control an audio receiver device to equalise loudness levels of audio signals output for playback on a connected audio playback device, the method comprising: outputting at least a first audio signal, ending output of the first audio signal, and then outputting a second audio signal in response to ending output of the second audio signal, wherein the first audio signal and the second audio signal are output to an audio output for playback on the connected audio playback device, the first audio signal and the second audio signal being digitally encoded in different audio formats, and the first audio signal being output at a first loudness level and the second audio signal being output at a second loudness level; controlling a connected display to output a graphical user interface that invites input from a user indicating the relative loudness of the first audio signal compared to the second audio signal, wherein the graphical user interface permits the user to select one of the first loudness level of the first audio signal and the second loudness level of the second audio signal as being the loudest of the output first loudness level and the subsequently output second loudness level; receiving a user input from the user via the graphical user interface that is output on the connected display, wherein the user input corresponds to a selection the first loudness level of the first audio signal or the second loudness level of the second audio signal; based on the user input that corresponds to the selection the first loudness level of the first audio signal or the second loudness level of the second audio signal, adjusting at least one of the first loudness level and the second loudness level, repeating output of the first loudness level and the second loudness level after one of the first loudness level and the second loudness level has been adjusted; receiving a new user input from the user via the graphical user interface that is output on the connected display, wherein the new user input corresponds a next selection the first loudness level of the first audio signal or the second loudness level of the second audio signal; and based on the new user input that corresponds to the next selection the first loudness level of the first audio signal or the second loudness level of the second audio signal, further adjusting at least one of the first loudness level and the second loudness level, wherein repeating the output of the first audio signal and the second audio signal, and the further adjusting of one of the first audio signal or the second audio signal continues until the user indicates that the first loudness level and the second loudness level are perceived to be heard at the same loudness level; and in response to receiving the user indication that indicates the first loudness level and the second loudness level are perceived to be heard at the same loudness level, saving information corresponding to the user indication that indicates that the first loudness level and the second loudness level are perceived to be heard at the same loudness level, wherein the information is stored in a memory of the audio receiver device for future reproduction of the audio signals.
