摘要： In a system and method for encoding a sound field the orientation of a computing device may be detected. Several orientation indications may be used to detect the computing device orientation. The detected orientation may be relative to a sound field that is a spatial representation of an audible environment associated with the computing device. Microphones associated with the computing device may be selected in order to receive the sound field based on the detected orientation. The received sound field may be processed and encoded with associated descriptive information.

摘要： A system and method for sample rate adaption. The system and method provide for information derived from sampling at a first rate to be applied or processed at a second rate where the first and second rates differ in frequency and phase. The information is adapted from the first rate to the second rate. Then phase differences including phase introduced as by-product of adapting the frequencies are reduced by phase adaption.

摘要： In an adaptive phase discovery system a first audio signal is received via a first microphone and a second signal is received via a second microphone. Corresponding audio frames of the first and second signals are each transformed into the frequency domain and a plurality of frequency sub-bands are generated. A phase is determined for each frequency sub-band in each signal. Instantaneous phase differences are determined between the signals at each of the frequency sub-bands. Lower frequency instantaneous phase differences are filtered over time to determine current phase differences at lower frequencies. When SNR is high in lower frequency sub-bands, lower frequency sub-band phase differences are tracked to the higher frequency sub-bands. The tracked higher frequency phase differences are filtered over time to determine phase differences for the current frame. The phase differences may be used to rotate phases in each sub-band and sum signals and/or to reject off-axis signals.

摘要： A system and method for mitigating microphone hiss may obtain a frequency spectrum characteristic for a microphone. A microphone that has limited dynamic range may create microphone hiss in an output signal. The microphone hiss may prevent a reproduction of a sound field, represented in an output signal of the microphone, from being perceived as a natural environment. The microphone frequency spectrum may be obtained using static measurements or calculated dynamically. A virtual noise floor may be calculated responsive to the microphone frequency spectrum and a desired noise floor. Gain coefficients may be calculated responsive to the output signal of the microphone. The gain coefficients may be calculated to mitigate undesirable signal content including background noise and echoes. The calculated gain coefficients may be modified responsive to the virtual noise floor. The modified gain coefficients may allow a reproduction of the sound field to be perceived as a natural environment.

摘要： A system and method for modal progress dialog may provide progress feedback to a user when an application accesses or uses system resources on a computing platform. The application may access or use the system resource by invoking an operation via a system interface. Execution of the application may be blocked pending receiving a result of the system resource operation. The progress feedback may be provided by the system interface without the involvement of the application. The progress feedback may include displaying a progress dialog. The progress dialog may be displayed in a window associated with the application. The progress dialog may include a visual indication of a degree of completion of the system resource operation. The progress dialog may mitigate a user misinterpreting delays in completion of the system resource operation as misoperation or failure of the application.

摘要： In a system and method for maintaining the spatial stability of a sound field a balance gain may be calculated for two or more microphone signals. The balance gain may be associated with a spatial image in the sound field. Signal values may be calculated for each of the microphone. The signal values may be signal estimates or signal gains calculated to improve a characteristic of the microphone signals. The differences between the signal values associated with each microphone signal may be limited although some difference between signal values may be allowable. One or more microphone signals are adjusted responsive to the two or more balance gains and the signal gains to maintain the spatial stability of the sound field. The adjustments of one or more microphone signals may include mixing of two or more microphone. The signal gains are applied to the two or more microphone signals.

摘要： A system and method for vehicle energy management are described that take driving context into account to derive suggested vehicle control inputs to reduce energy consumption. Driving context may be based on information including, for example, traffic congestion and/or flow information for a travelled route, road topology information, traffic controls, weather conditions, vehicle characteristics, and other types of driving context information. The driving context may be used to derive suggested control inputs to reduce energy consumption. The suggested control inputs can, for example, be expressed as: a suggested road speed, suggested gear selection, rate of acceleration or rate of deceleration.

摘要： In a conditional multipass automatic speech recognition system, one or more intent templates may be received from an application. A spoken utterance is received and audio frames are generated from the utterance. The audio frames are compared to a first grammar. Recognized speech results are generated and unrecognized audio frames or low confidence frames are collected. One of one or more intent templates and one or more corresponding intent parameters may be determined based on the recognized speech results. The unrecognized audio frames may be conditionally compared to a second grammar in instances when additional information is requested, relative to the determined intent template or the corresponding intent parameters.

摘要： A system and method for forwarding a graphics command stream. A graphics renderer may receive a graphics command stream where the graphic command stream contains graphical information renderable as a graphical image. The graphics renderer may process the received graphics command stream to generate a processed graphics stream where the processed graphics stream contains equivalent graphical information to the graphical information contained in the graphics command stream. A source redirector may encode the processed graphics stream to generate a formatted graphics stream. A source protocol stack may send the formatted graphics stream to a target graphics component. A target redirector may receive and decode the formatted graphics stream. The target redirector may process the decoded formatted graphics stream to generate a target graphics command stream where the target command stream contains equivalent graphical information contained in the formatted graphics stream.
