Abstract: A remote commander (RC) for a TV or other entertainment system component has a microphone. A device can query the RC for its serial number, access the Internet with the serial number to look up characteristics of the microphone, and then knowing the characteristics, use the RC microphone to detect sound such as speaker test chirps to calibrate an audio system in a convenient and user-friendly manner while achieving the accuracy of calibration that can only be obtained by using a calibrated microphone system.

Abstract: Implementations generally provide simulated audience reactions to performers on camera. In some implementations, a method includes receiving a video of a target user from a target client device. The method further includes providing the video to a plurality of audience client devices. The method further includes receiving raw audience feedback from the plurality of audience client devices. The method further includes providing simulated audience feedback to the target client device based on one or more predetermined audience feedback policies, wherein the target client device provides the simulated audience feedback to the target user.

Abstract: A head related transfer function (HRTF), which can be considered as biometric data is used to authenticate a user from whom the HRTF is derived. The HRTF may be used for authentication in combination with other biometric data such as retina scan or fingerprint to render two-factor biometric authentication. The HRTF used for authentication is encrypted for security.

Abstract: An audio reproduction device and method for audio control based on room-correction (RC) and head related transfer function (HRTF) are provided. The audio reproduction device includes a speaker that reproduces a first audio signal. The audio reproduction device receives a plurality of second audio signals indicative of frequency responses captured based on the first audio signal and captured by a plurality of audio capturing devices positioned on a head wearable device of a user present within an enclosed physical space. The audio reproduction device determines RC preset for one or more RC filters associated with the speaker, based on the captured frequency responses. The audio reproduction device further determines HRTF associated with the user based on the captured frequency responses, and user-specific information of the user. The audio reproduction device further controls audio reproduction of the speaker based on the determined RC preset and the determined HRTF.

Abstract: Audio speaker angular determination is made using sensor fusion technology involving an accelerometer, gyroscope, and magnetometer (compass). All speakers in an audio system use their magnetometers to determine their orientation relative to magnetic north. A group owner (typically the center channel or sound bar) gathers the orientation information from all speakers in the system. The group owner determines the angle of orientation of all speakers relative to its own orientation. Changes in angular orientation are sensed by the gyroscopes. For example, during calibration, the user can be told to rotate a certain speaker in the system, and the gyroscope measures the change and reports to the group owner. An indication is presented as to whether the new angle is good, or more is required. The gyroscope in combination with the accelerometer senses changes of angular orientation to aim height speakers downward towards the listening position or bottom speakers upward.

Abstract: An audio reproduction device and method for room correction based on occupancy determination is provided. The audio reproduction device includes a speaker which reproduces audio, and includes a memory which stores a plurality of room-correction (RC) presets. The audio reproduction of the speaker is controlled within an enclosed physical space based on each of the plurality of RC presets. The audio reproduction device receives an occupancy signal from at least one sensor communicatively coupled with the audio reproduction device. The audio reproduction device further determines a number of people of a set of people, present in the enclosed physical space, based on the received occupancy signal. The audio reproduction device retrieves first room-correction (RC) preset from the stored plurality of RC presets based on the determined number of people. The audio reproduction device further controls the audio reproduction of the speaker based on the retrieved first RC preset.

Abstract: A personalized HRTF is generated from a generic HRTF by having a person don headphones, then select a generic HRTF model from a list. Test signals emulating sounds from a source at a specific virtual speaker location are played on the headphones, and the person indicates where he thinks the emulated sounds are coming from. Any difference between the virtual speaker location and the “heard” location is used to adjust the parameters (amplitude, phase, and frequency response) of the generic HRTF to render a HRTF personalized to the listening person.

Abstract: A networked speaker system includes plural speaker assemblies around the perimeter of a space with sound axes oriented up and inward into the space. Each speaker assembly includes an audio transducer to output demanded sound and a noise cancelation transducer which is driven to cancel sound from other speaker assemblies in the space based on signals from a microphone on the speaker assembly and location and device information from the other speaker assemblies.

Abstract: A cloud-based HRTF repository system that can be accessed via a public application program interface (API) on the remote repository server to permit individual users of audio-capable client devices to upload and store personalized HRTFs and basic device data in an open format. The cloud server repository includes a computer readable non-volatile memory which further includes a program memory portion comprising an application program interface (API) module configured for receiving HRTF data from a client device, or from a brand manufacturer, and for sending HRTF data to a client device. A brand manufacturer can upload HRTF data to the cloud-based HRTF repository system either directly from their branded companion app in a client device, or optionally via their own cloud server.

Abstract: A visual component is added to a 3D audio stream to present on a display at the player side a visual representation of objects in the 3D audio, enabling the user to better understand what is happening in the 3D audio experience. The visual representation may include visual objects with the same location and movement in 3D space as audio objects being played.

Abstract: A personalized room related transfer function (RRTF) for sound bars and speakers within a specific room is generated without the need for photographs of the listener's head or microphones in a headphone apparatus. A smart device aids the listener in creating his own RRTF by enabling the listener to select a general RRTF model based on the specific sound bar setup (e.g., sound bar; sound bar+subwoofer; sound bar+rear speakers+height; etc.) from a set of general RRTFs downloaded locally or from the cloud. A test signal is played from a specific driver of the sound bar, and the listener identifies a location at which he would like the perceived sound to originate. If the driver location signal and desired location are not the same, the app adjusts parameters and replays the test signal until the driver signal and the desired location are the same.

Abstract: An audio video device (AVD) is activated post-sale using an unlock code issued during the purchase. The buyer connects to his home network and enters the unlock code issued in the store at the point of sale. Then a server associated with the seller can complete the transaction and unlock the AVD for full functionality. In the event the AVD is reported stolen before activation, it can be blocked from use. When in the reduced functionality mode” the AVD can remain in demonstration mode or other reduced functionality state (e.g., only works with HDMI1).
