Apparatus and associated methods for capture of spatial audio

A method, the method comprising:

• receiving spatial audio data comprising audio captured from one or more audio sources in a space extending around a capture device and directional information indicative of at least a direction towards said one or more audio sources, wherein the spatial audio data is captured by said capture device;
• receiving video imagery captured by a camera of the capture device, the video imagery having a field of view, wherein the extent of the space from which the spatial audio data is captured is greater than the field of view;
• associating each of one or more audio sources, determined from the directional information, with, for audio sources within the field of view, a region of the video imagery that corresponds to the direction towards the audio source, and, for audio sources outside the field of view, a part of an out-of-view graphic that corresponds to the direction towards the audio source, the out-of-view graphic indicative of the spatial extent of the space outside the field of view;
• providing for display of the video imagery on a display along with the out-of-view graphic;
• receiving user input to select the region of the video imagery or the part of the out-of-view graphic;
• and
• providing for control of at least one audio capture property of a selected one of said one or more audio sources, wherein said selected one of said one or more audio sources comprises one of the one or more audio sources that is associated with the region or part selected by the user input,
• wherein the out-of-view graphic indicative of the spatial extent of the space outside the field of view further comprises at least one of:
• a line, wherein the position along the line from one end thereof to the other represents the direction from which the audio of the audio sources that are associated with the out-of-view graphic is received, wherein the one end of the line represents a direction that corresponds to at least a first edge of the field of view and the other end of the line represents a direction that corresponds to at least a second edge of the field of view opposite the first edge;
• or
• a sector of an ellipse, wherein the position within the sector represents the direction from which the audio of the audio sources that are associated with the out-of-view graphic is received, wherein a first portion of the sector represents a direction that corresponds to at least a first edge of the field of view and a second portion of the sector represents a direction that corresponds to at least a second edge of the field of view opposite the first edge.

A non-transitory computer readable medium comprising program instructions stored thereon for performing at least the following:

• receiving spatial audio data comprising audio captured from one or more audio sources in a space extending around a capture device and directional information indicative of at least a direction towards said one or more audio sources, wherein the spatial audio data is captured by said capture device;
• receiving video imagery captured by a camera of the capture device, the video imagery having a field of view, wherein the extent of the space from which the spatial audio data is captured is greater than the field of view;
• associating each of one or more audio sources, determined from the directional information, with, for audio sources within the field of view, a region of the video imagery that corresponds to the direction towards the audio source, and, for audio sources outside the field of view, a part of an out-of-view graphic that corresponds to the direction towards the audio source, the out-of-view graphic indicative of the spatial extent of the space outside the field of view;
• providing for display of the video imagery on a display along with the out-of-view graphic;
• receiving user input to select the region of the video imagery or the part of the out-of-view graphic;
• and
• providing for control of at least one audio capture property of a selected one of said one or more audio sources, wherein said selected one of said one or more audio sources comprises one of the one or more audio sources that is associated with the region or part selected by the user input,
• wherein the out-of-view graphic indicative of the spatial extent of the space outside the field of view further comprises at least one of:
• a line, wherein the position along the line from one end thereof to the other represents the direction from which the audio of the audio sources that are associated with the out-of-view graphic is received, wherein the one end of the line represents a direction that corresponds to at least a first edge of the field of view and the other end of the line represents a direction that corresponds to at least a second edge of the field of view opposite the first edge;
• or
• a sector of an ellipse, wherein the position within the sector represents the direction from which the audio of the audio sources that are associated with the out-of-view graphic is received, wherein a first portion of the sector represents a direction that corresponds to at least a first edge of the field of view and a second portion of the sector represents a direction that corresponds to at least a second edge of the field of view opposite the first edge.
