Abstract: A heating, ventilation, and/or air conditioning (HVAC) system in accordance with present embodiments includes a housing, one or more sensing units disposed within the housing, and a controller disposed within the housing. The controller is operable to communicate with the one or more sensing units through a wireless communication link to receive sensed data, and analyze the sensed data by applying one or more data processing techniques.

Abstract: Methods, systems, and computer program products for simulating propagation of sound in a static scene can be operated for pre-computing a transfer operator for simulating results of sound reflection within a modeled scene, simulating distribution of sound energy from a sound source positioned within the scene, applying the transfer operator to the distribution of sound energy from the sound source to compute simulated sound at a plurality of points within the scene, and simulating collection of sound energy from the plurality of points within the scene to a listener positioned within the scene.

Abstract: In some embodiments, a method applying reverberation to audio from at least one client of a set of clients which share a virtual environment, including by asserting position data and at least one input audio stream to a server, selecting (in the server) a reverberation filter for each input audio stream in response to the position data and generating wet audio by applying to the input audio an early reverberation part of the selected reverberation filter. Typically, a client applies a late reverberation filter to the wet audio using metadata from the server. In other embodiments, a server selects a reverberation filter for application to audio in response to position data, asserts the audio and metadata indicative of the filter, and a client applies the filter to the audio using the metadata. Other aspects are systems, servers, and client devices configured to perform any embodiment of the method.

Abstract: Methods, systems, and computer program products for simulating sound propagation can be operable to define a sound source position within a modeled scene having a given geometry and construct a visibility tree for modeling sound propagation paths within the scene. Using from-region visibility techniques to model sound diffraction and from-point visibility technique to model specular sound reflections within the scene, the size of the visibility tree can be reduced. Using the visibility tree, an impulse response can be generated for the scene, and the impulse response can be used to simulate sound propagation in the scene.
