Abstract: A method performed by a portable media player device. The method receives a microphone signal that includes audio content output by an audio playback device via a loudspeaker. The method determines identification information regarding the audio content, wherein the identification information is determined through an acoustic signal analysis of the microphone signal. In response to determining that the audio playback device has ceased outputting the audio content, the method retrieves from local memory of the portable media player device or a remote device with which the portable media player device is communicatively coupled, an audio signal that corresponds to the audio content and drives a speaker that is not part of the audio playback device using the audio signal to continue outputting the audio content and any additional audio content related to the audio content.

Abstract: The present disclosure relates to techniques for transitioning between imagery and sounds of two different environments, such as a virtual environment and a real environment. A view of a first environment and audio associated with the first environment are provided. In response to detecting a transition event, a view of the first environment combined with a second environment is provided. The combined view includes imagery of the first environment at a first visibility value and imagery of the second environment at a second visibility value. In addition, in response to detecting a transition event, the first environment audio is mixed with audio associated with the second environment.

Abstract: The present disclosure relates to techniques for presenting a combined view of a virtual environment and a real environment in response to detecting a transition event associated with an object in the real environment. While presenting the combined view, if an input of a first type is detected, the combined view is adjusted by increasing the visibility of imagery of the virtual environment and decreasing the visibility of imagery of the real environment. If an input of a second type is detected, the combined view is adjusted by decreasing the visibility of the imagery of the virtual environment and increasing the visibility of the imagery of the real environment.

Abstract: The present disclosure relates to techniques for inserting imagery from a real environment into a virtual environment. While presenting (e.g., displaying) the virtual environment at an electronic device, a proximity of the electronic device to a physical object located in a real environment is detected. In response to detecting that the proximity of the electronic device to the physical object is less than a first threshold distance, imagery of the physical object is isolated from other imagery of the real environment. The isolated imagery of the physical object is inserted into the virtual environment at a location corresponding to the location of the physical object in the real environment. The imagery of the physical object has a first visibility value associated with the proximity of the electronic device to the physical object.

Abstract: A method for reducing gain for audio amplification by an audio system having a tweeter channel, an optional midrange channel, and a woofer channel. Gain of the woofer channel is reduced simultaneously with reducing gain of the tweeter channel, both responsive to detecting the same instance of overloading (overdriving) the woofer channel. Other aspects are also described and claimed.

Abstract: Audio processing with audio transparency can include receiving a user content audio signal and receiving a microphone signal. The microphone signal can contain sensed sound of a user environment. Strength of the sensed sound can be increased based on strength of the user content audio signal, to reduce a masking of the sensed sound during playback. The sensed sound and the user content audio signal can be combined in a composite output audio signal used to drive a speaker. Other aspects are also described and claimed.

Abstract: An audio asset library containing audio assets formatted in accordance with a file format for spatial audio includes asset metadata that enables simulated reality (SR) application developers to compose sounds for use in SR applications. The audio assets are formatted to include audio data encoding a sound capable of being composed into a SR application along with asset metadata describing not only how the sound was encoded, but also how a listener in SR environment experiences the sound. A SR developer platform is configured so that developers can compose sound for SR objects using audio assets stored in the audio library, including editing the asset metadata to include transformation parameters that support dynamic transformation of the asset metadata in the SR environment to alter how the SR listener experiences the composed sound. Other embodiments are also described and claimed.
