Abstract: A head-worn sound reproduction device is provided in the form of left and right earphones, which can either be clipped to each ear or mounted on other headgear. The earphones deliver high fidelity audio to a user's eardrums from near-ear range, in a lightweight form factor that is fully “non-blocking” (allows coupling in and natural hearing of ambient sound). Each earphone has a woofer component that produces bass frequencies, and a tweeter component that produces treble frequencies. The woofer outputs the bass frequencies from a position close to the ear canal, while the tweeter outputs treble frequencies from a position that is either close to the ear canal or further away. In certain embodiments, the tweeter is significantly further from the ear canal than the woofer, leading to a more expansive perceived “sound stage”, but still with a “pure” listening experience.

Abstract: Systems and methods for capturing audio which can be used in applications such as virtual reality, augmented reality, and mixed reality systems. Some systems may include a plurality of distributed monitoring devices in an environment, each having a microphone and a location tracking unit. The system can capture audio signals while also capturing location tracking signals which indicate the locations of the monitoring devices over time during capture of the audio signals. The system can generate a representation of at least a portion of a sound wave field in the environment based on the audio signals and the location tracking signals. The system may also determine one or more acoustic properties of the environment based on the audio signals and the location tracking signals.

Abstract: The subject disclosure is directed towards a technology that may be used in an audio processing environment. Nodes of an audio flow graph are associated with virtual mix buffers. As the flow graph is processed, commands and virtual mix buffer data are provided to audio fixed-function processing blocks. Each virtual mix buffer is mapped to a physical mix buffer, and the associated command is executed with respect to the physical mix buffer. One physical mix buffer mix buffer may be used as an input data buffer for the audio fixed-function processing block, and another physical mix buffer as an output data buffer, for example.

Abstract: A handheld device includes: an orientation sensor; an audio processor connected to the orientation sensor and adapted to receive orientation information from the orientation sensor; and a plurality of speakers through which audio content is provided, wherein the audio processor modifies the audio signal provided to the speakers based, at least in part, on the orientation information. A method of controlling audio content provided through a plurality of speakers in the device includes the steps of: determining a neutral orientation of the sweet spot; using information from the orientation sensor to measure the relative orientation of the device; and determining whether the relative orientation of the device has changed. If the relative orientation of the device has changed, modifying the audio content provided through the speakers.

Abstract: Communication between a game console having a communication port and a portable device is facilitated by determining that a portable device has been directly connected to the communication port, determining the protocol associated with the portable device, and communicating with the portable device using a driver associated with the determined protocol. An ancillary application may handle the communication between the game console and the portable device while a game or entertainment application executes concurrently on the game console. The game application may execute in a reserved predetermined amount of hardware resources of the game console while the ancillary application may execute concurrently using the remaining hardware resources.

Abstract: Systems and methods for providing multi-channel audio using a reduced amount of resources for the decoding process. A 5.1 channel audio stream is divided into three stereo streams. The packets from each of three stereo streams are multiplexed to create a pseudo-5.1 channel audio stream. The pseudo 5.1 channel audio stream is then decoded and demultiplexed at the output to create the output 5.1 channel audio sound. As such, the decoder resources only have decode a single pseudo 5.1 stream. This technique is equally applicable to 7.1 or other multi-channel formats.

Abstract: A user of a game system can replace background music from a game with the user's selected background music, while still hearing any other audio streams (e.g. sound effects related to gameplay). A music engine and system audio mixer allow the playback of the user's requested replacement music. The game tags background music streams with an identifier indicating that they are background music, and such streams are muted at the music engine and system audio mixer (if the game is using the provided music engine in order to play the game's audio streams) or by the game if the game is using a game music engine and has received information indicating that a mute request has been issued.

Abstract: A system and method for enabling users and developers to store data on a number of different types of local and remote devices connected to a multimedia console or a gaming console. The range of available storage devices creates issues that are addressed to avoid apparent inconsistencies in storage performance (e.g. latency). A consistent method of reading and writing data is provided such that end users and developers do not have to be concerned with restrictions and limitations inherent to various devices.
