Abstract: Technologies are provided for a programmable hardware proxy (PHP) for assessment of control logic. A control sequence that controls execution of an automation task within a physical automation system can be accessed to generate a virtual representation of physical control connections among sensor devices and a control device associated with an automation subsystem. The virtual representation constitutes a realistic virtual control interface that can be exposed to the automation subsystem in virtual domain. The virtual control interface can replace the control device in virtual domain, while preserving the functionality of the control device. The virtual control interface constitutes the PHP for the sensors devices and the control device. The PHP can be used to assess control logic for the automation subsystem, without reliance on hardware present in the automation subsystems.

Abstract: The disclosed computer-implemented method may include applying, via a sound reproduction system, sound cancellation that reduces an amplitude of various sound signals. The method further includes identifying, among the sound signals, an external sound whose amplitude is to be reduced by the sound cancellation. The method then includes analyzing the identified external sound to determine whether the identified external sound is to be made audible to a user and, upon determining that the external sound is to be made audible to the user, the method includes modifying the sound cancellation so that the identified external sound is made audible to the user. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: Techniques are described for generating spatialized audio content based on head orientation information and torso orientation information obtained from a drift compensation system. The drift compensation system compensates for drift in measurements performed by an inertial measurement unit (IMU), based on biological constraints pertaining to a user. The head orientation information is applied to a first set of filters to generate intermediate audio content. In turn, the torso orientation information and the intermediate audio content are applied to a second set of filters to generate the spatialized audio content. The first set of filters includes one or more audio filters that receive an input audio signal corresponding to a left channel. The second set of filters includes one or more audio filters that receive an input audio signal corresponding to a right channel. The spatialized audio content includes separate output signals for the left channel and the right channel.

Abstract: Embodiments relate to binaural spatialization of more than two sound sources on two audio channels of an audio system. Sound signals each emitted from a corresponding sound source are collected, and a respective virtual position within an angular range of a sound scene is assigned to each sound source. Multi-source audio signals are generated by panning each sound signal according to the respective virtual position. A first multi-source audio signal is spatialized to a first direction to generate a first left signal and a first right signal. A second multi-source audio signal is spatialized to a second direction to generate a second left signal and a second right signal. A binaural signal is generated using the first left signal, the second left signal, the first right signal, and the second right signal. The binaural signal is such that each sound source appears to originate from its respective virtual position.
