A system and method facilitating signal enhancement utilizing an adaptive filter is provided. The invention includes an adaptive filter that filters an input based upon a plurality of adaptive coefficients, the adaptive filter modifying at least one of the adaptive coefficients based on a feedback output. The invention further includes a feedback component that provides the feedback output based, at least in part, upon a non-linear function of the acoustic reverberation reduced output. The invention further provides a noise statistics component that stores noise statistics associated with a noise portion of an input signal and a signal+noise statistics component that stores signal+noise statistics associated with a signal and noise portion of the input signal. The invention further provides a spatial filter that provides an output signal based, at least in part, upon a filtered input signal, the filtering being based, at least in part, upon a weighted error calculation of the noise statistics and the signal+noise statistics.

Microphone array signal enhancement

A prototyping tool is provided to an artistic team, which can use the tool to experiment with, demonstrate, and communicate aspects of the user interface interaction with various user interface elements. These user interface elements can be defined within a layered graphics representation of the user interface artwork, rather than individual flattened graphics files. By setting properties on individual user interface elements through the prototyping tool, the artistic team can review how the elements will appear and behave during typical interaction with a user. Furthermore, a description of the interaction properties and relationships of these user interface elements, as defined by the artistic team, is captured for communication to a programming team. The programming team can then load the layered graphical representation and the interaction description to implement the user interface interactivity developed and proposed by the artistic team.

Adding interactivity to artwork

A design application uses metadata-based techniques (e.g., runtime reflection) to examine class metadata of design objects. A key object is provided by a programmer of a graphical design application to generically animate properties of design objects in one or more animation frames. Using runtime reflection or other metadata techniques, the key object finds properties of each design object and updates specified property values for animated display in one or more animation frames. A key set object is provided to group multiple key objects into a sequence of key frames along a timeline. In this manner, a programmer can provide a small amount of support program code (e.g., a key class and a key set class) that can be associated with selected design objects at runtime of the design application in order to allow an animation designer to decide which design objects and which properties to animate.

Animating objects using metadata

A networked computing environment in which a computing device is configured according to configuration information associated with a detected communication network is presented. As a computer detects a change in the network to which it is connected, the computer obtains configuration information associated with the newly detected network. According to the configuration information, the computer is configured such that some computer functions are presented and/or made available and accessible, while other computer functions are hidden and/or made unavailable and inaccessible.

A system and method facilitating signal enhancement utilizing an adaptive filter is provided. The invention includes an adaptive filter that filters an input based upon a plurality of adaptive coefficients and modifies the adaptive coefficients based on a feedback output. A feedback component provides the feedback output based, at least in part, upon a non-linear function of the acoustic reverberation reduced output. Optionally, the system can further include a linear prediction (LP) analyzer and/or a LP synthesis filter. The system can enhance signal(s), for example, to improve the quality of speech that is acquired by a microphone by reducing reverberation. The system utilizes, at least in part, the principle that certain characteristics of reverberated speech are measurably different from corresponding characteristics of clean speech. The system can employ a filter technology (e.g., reverberation reducing) based on a non-linear function, for example, the kurtosis metric.
