Techniques for performing spatial audio processing based on a listening mode of a wearable device are described. An example technique includes detecting a listening mode that is activated on the wearable device. A set of spatial audio processing settings is determined based on the listening mode. The set of spatial audio processing settings is applied to a spatial audio rendering algorithm while audio content is output from the wearable device. Another example technique includes detecting a listening mode of the wearable device that has been activated for listening to audio content. A head-tracking mode of the wearable device is controlled based on the listening mode.

Adaptive spatial audio processing

The disclosure provides an approach for adaptive sound scene rotation. A method of adaptively rendering audio is provided. The method includes obtaining an audio signal. The audio signal is associated with one or more audio channels and each audio channel is associated with a position of an audio source with respect to a reference point within a local reproduction system. The method includes determining a rotation of a user with respect to a reference orientation about the reference position within the local reproduction system and determining a system rotation based on the rotation of the user. The method includes rendering the audio signal to one or more loudspeakers of a plurality of loudspeakers within the local reproduction system, based on the system rotation, a number of the plurality of loudspeakers, and the plurality of positions of the plurality of loudspeakers, to compensate for the rotation of the user.

Adaptive sound scene rotation

The disclosure provides an approach for adaptive sound image width enhancement. A method of adaptively correcting sound image width is provided. The method includes obtaining an audio signal. The audio signal is associated with one or more audio channels. Each audio channel is associated with a position of an audio source with respect to a reference point within a local reproduction system. The method includes decomposing the audio signal into mid signal, side signal, and unprocessed signal components. The method includes applying respective correction gains to each of the mid signal, side signal, and unprocessed signal components. The respective correction gains are based on a physical distance between a first loudspeaker and a second loudspeaker within the local reproduction system. The method includes rendering, after applying the respective correction gains, the mid signal, side signal, and unprocessed signal components to the first and second loudspeakers.

Adaptive sound image width enhancement

Techniques for generating an auditory memory for an auditory event are described. An example technique includes obtaining a first audio content associated with an event in an environment. At least one attribute of the environment is determined, based on evaluating the first audio content. At least one emotional attribute associated with the event in the environment is determined, based on evaluating the first audio content. A second audio content is determined, based at least in part on the at least one attribute of the environment. A third audio content is determined, based at least in part on the at least one emotional attribute. An auditory memory including fourth audio content associated with the event in the environment is generated, based on the first audio content, the second audio content, and the third audio content.
