Graphical user interface for calibrating a surround sound system

A method for calibrating a multichannel surround sound system with a plurality of loudspeakers, the method comprising:

• under control of a hardware processor,
• outputting a graphical user interface for display, the graphical user interface comprising a model room comprising a plurality of icons indicating initial positions of the plurality of loudspeakers;
• receiving user input through the graphical user interface, the user input comprising adjusting a first icon in the plurality of icons corresponding to a first loudspeaker in the plurality of loudspeakers inside the model room, the adjusted first icon indicating a modified position of the first loudspeaker;
• in response to receiving the user input, estimating an actual location of the first loudspeaker using test signals;
• further automatically adjusting the first icon corresponding to the first loudspeaker based on the estimated actual location of the first loudspeaker, the further automatically adjusted first icon indicating a second modified position of the first loudspeaker;
• performing a spatial calibration for the multichannel surround sound system based on the second modified position of the first loudspeaker;
• and
• applying the spatial calibration to audio for playback through the plurality of loudspeakers.

An apparatus for calibrating a multichannel surround sound system including one or more loudspeakers, the apparatus comprising:

• a graphical user interface provided by a client device, the graphical user interface configured to:
• display a model room indicating estimated locations of the one or more loudspeakers;
• and
• receive user input through the graphical user interface, the user input including moving an icon representing a first loudspeaker in the one or more loudspeakers inside the model room;
• and
• a calibration engine configured to:
• estimate an actual location of the first loudspeaker using test signals;
• provide the estimated actual location of the first loudspeaker to the client device such that the icon representing the first loudspeaker is automatically moved by the client device to a new position inside the model room corresponding to the estimated actual location;
• and
• perform a spatial calibration for the multichannel surround sound system based at least on the new position of the icon representing the first loudspeaker.
