Visualizing spatial audio

A method comprising:

• for a first auditory spatial cue decoded from a spatialized audio signal,
• determining which of a plurality of positions indicated in a map of audio source positions corresponds to the first auditory spatial cue;
• calculating a value of a first visual feature based on an audio intensity value indicated in the first auditory spatial cue;
• generating a first visual spatial cue based on the calculated value for the first visual feature and the position of the plurality of positions determined as corresponding to the first auditory spatial cue;
• communicating the first visual spatial cue for rendering in a graphical user interface in coordination with rendering of the first auditory spatial cue and corresponding audio with an audio output device;
• determining a second auditory spatial cue does not correspond to one of the plurality of positions indicated in the map of audio source positions;
• determining at least two of the positions corresponding to the second auditory spatial cue;
• calculating a value of a second visual feature based on audio intensity values of the at least two positions;
• and
• determining a position of the second auditory spatial cue, wherein the position is not one of the plurality of positions indicated in the map of audio source positions.

A system comprising:

• a processor;
• and
• a machine-readable medium having a program code executable by the processor to cause the system to,
• for a first auditory spatial cue decoded from a spatialized audio signal,
• determine which of a plurality of positions indicated in a map of audio source positions corresponds to the first auditory spatial cue,
• calculate a value of a first visual feature based on an audio intensity value indicated in the first auditory spatial cue,
• generate a first visual spatial cue based on the calculated value for the first visual feature and the position of the plurality of positions determined as corresponding to the first auditory spatial cue,
• communicate the first visual spatial cue for rendering the first visual spatial cue around a listener displayed in a graphical user interface in coordination with rendering of the first auditory spatial cue and corresponding audio with an audio output device of the listener, and
• synchronize communicating of the first visual spatial cue for rendering with communicating the first auditory spatial cue for rendering;
• wherein the communication of the first visual spatial cue for rendering and the communication of the first auditory spatial cue for rendering are synchronized using buffering.

A non-transitory, computer-readable medium having instructions stored thereon that are executable by a computing device to perform operations comprising:

• for a first auditory spatial cue decoded from a spatialized audio signal,
• determining which of a plurality of positions indicated in a map of audio source positions corresponds to the first auditory spatial cue;
• calculating a value of a first visual feature based on an audio intensity value indicated in the first auditory spatial cue;
• generating a first visual spatial cue based on the calculated value for the first visual feature and the position of the plurality of positions determined as corresponding to the first auditory spatial cue;
• communicating the first visual spatial cue for rendering in the first visual spatial cue around a listener displayed a graphical user interface in coordination with rendering of the first auditory spatial cue and corresponding audio with an audio output device of the listener;
• and
• synchronizing communicating of the first visual spatial cue for rendering with communicating the first auditory spatial cue for rendering, wherein the communication of the first visual spatial cue for rendering and the communication of the first auditory spatial cue for rendering are synchronized using buffering;
• wherein the spatialized audio signal comprises object-based audio and the instructions for determining which of the plurality of positions indicated in the map of audio source positions corresponds to the first auditory spatial cue comprises instructions for determining spatial information from metadata decoded from the spatialized audio signal and determining the corresponding position based on the metadata indicated in the first auditory spatial cue.
