In an example, a method for encoding a spatial audio signal can include receiving audio scene information from an audio capture source in an environment, and receiving a depth characteristic of a first object in the environment. The depth characteristic can be determined using information from a depth sensor. A correlation can be identified between at least a portion of the audio scene information and the first object. The spatial audio signal can be encoded using the portion of the audio scene and the depth characteristic of the first object.

Abstract: Embodiments of systems and methods are described for estimating a position of a loudspeaker and notifying a listener if an abnormal condition is detected, such as an incorrect loudspeaker orientation or an obstruction in a path between the loudspeaker and a microphone array. For example, a front component of a multi-channel surround sound system may include the microphone array and a position estimation engine. The position estimation engine may estimate the distance between the loudspeaker and the microphone array. In addition, the position estimation engine may estimate an angle of the loudspeaker using a first technique. The position estimation engine may also estimate an angle of the loudspeaker using a second technique. The two angles can be processed to determine whether the abnormal condition exists. If the abnormal condition exists, a listener can be notified and be provided with suggestions for resolving the issue in a graphical user interface.

For example, the multi-speaker system can include an array of forward-facing speakers, one or more upward-facing speakers, and/or one or more side-facing speakers. Filters coupled to any two of the speakers in the multi-speaker system can generate audio signals output by the coupled speakers to reduce, attenuate, or cancel a portion of an audio signal output by one or more non-front-facing speakers that acoustically propagates along a direct path from the respective non-front-facing speaker to a listening position in a listening area in front of the multi-speaker system.

Abstract: A graphical user interface (GUI) can specify a three-dimensional position. The GUI can include a puck that is user-positionable in two dimensions. A distance between the puck and a reference point on the graphical user interface can determine a radius of the three-dimensional position. An azimuthal orientation of the puck with respect to the reference point can determine an azimuthal angle of the three-dimensional position. The GUI can include an elevation controller, separate from the puck, to specify an elevation of the three-dimensional position. The elevation controller can specify an elevation angle, which can determine a position along the surface of a virtual sphere as a function of elevation angle. In addition, or alternatively, the elevation controller can specify an elevation height, which can determine a position along a line, such as directly upward or downward, as a function of elevation height.
