  • Patent number: 10448188
    Abstract: For generating 3D audio content from a two-channel stereo signal, the stereo signal (x(t)) is partitioned into overlapping sample blocks and is transformed into time-frequency domain. From the stereo signal directional and ambient signal components are separated, wherein the estimated directions of the directional components are changed by a predetermined factor, wherein, if changes are within a predetermined interval, they are combined in order to form a directional center channel object signal. For the other directions an encoding to Higher Order Ambisonics (HOA) is performed. Additional ambient signal channels are generated by de-correlation and rating by gain factors, followed by encoding to HOA. The directional HOA signals and the ambient HOA signals are combined, and the combined HOA signal and the center channel object signals are transformed to time domain.

  • Patent number: 10436828
    Abstract: A load detector for an audio system comprising a closed-loop amplifier is described. The load detector includes a noise detector configured to be coupled to the output of the closed-loop amplifier. The noise detector detects a noise signal at least partially generated by the amplifier. The generated noise signal comprises frequencies outside the audible frequency range due to the noise shaping of the amplifier. The load detector further includes a parameter calculation module having an input coupled to the output of the noise detector and an output. The parameter calculation module is configured to determine a parameter value relating to an impedance of the amplifier output load from the detected noise signal and to output a load detection signal dependent on the determined parameter value. The load detector may detect the presence of a load such as a tweeter without generating a reference signal.

  • Patent number: 10433046
    Abstract: An improved system and method for reducing the ambient noise experienced by a user listening to an earpiece without the use of a microphone is disclosed. An “ambient noise signal” created by the sound pressure wave of the ambient noise acting on the earpiece transducer is obtained. In some embodiments, the ambient noise signal is inverted and fed back, and the inverted signal is added to the intended audio signal being sent to the earpiece so that the ambient noise is cancelled. In other embodiments, a processor receives the ambient noise signal and predicts the modification to the intended audio signal needed to counteract the ambient noise. The ambient noise signal may be obtained by comparing the actual signal across the earpiece transducer to the intended audio signal, or by detecting variations in the current across the transducer from the current generated to drive the transducer.

  • Patent number: 10425764
    Abstract: A bass management system and method for mitigating bass management errors by using explicit information available in the object audio rendering process and deriving the correct subwoofer contribution for each audio object. Embodiments of the bass management system and method are used to maintain the correct balance of the bass reproduced by the subwoofer relative to the sound coming out of the other speakers. The system and method are useful for a variety of different speaker configurations, including speaker configurations having different speaker sub-zones. Power-normalized gain coefficients for each speaker are combined and the power of the combined gain coefficients is computed and used to obtain a power-preserving subwoofer contribution coefficient. This subwoofer contribution coefficient is applied to the bass portion of the audio signal and audio objects to determine the contribution of a particular subwoofer.

  • Patent number: 10410491
    Abstract: A method is provided that generates a sound illusion profile to replicate a quantity of resources arriving at an incident scene. A virtual partner or the like determines that an incident has escalated from a first severity level to a second severity level. The virtual partner determines a quantity of resources needed to deescalate the incident to the first severity level. A sound illusion profile is generated to replicate a sound associated with the quantity of resources. A signal is sent to one or more speaker devices in a region surrounding the location of the incident to generate an output sound based on the sound illusion profile.

  • Patent number: 10412529
    Abstract: A virtual reality (VR) audio rendering system and method using pre-computed impulse responses (IRs) to generate audio frames in a VR setting for rendering. Based on a current position of a user or a VR object, a set of possible motions are predicted and a set of IRs are pre-computed by using a Geometric Acoustic (GA) model of a virtual scene. Once a position change is actually detected, one of the pre-computed IRs is selected and convolved with a set of audio frames to generate modified audio frames for rendering. As the modified audio frames are generated by using pre-computed IR without requiring intensive ray tracing computations, the audio latency can be significantly reduced.

    Abstract: One or more computing devices, systems, and/or methods for controlling a volume level of a device are provided. For example, a first button corresponding to increasing a volume level of a device may be selected, and the volume level may be increased by a first amount (e.g., 10%). A second button corresponding to decreasing the volume level of the device may be selected. If the second button is determined to have been selected within a threshold period of time after the selection of the first button, the volume level may be decreased by a second amount (e.g., 5%). If the second button is determined to have not been selected within the threshold period of time after the selection of the first button, the volume level may be decreased by the first amount (e.g., 10%).

  • Patent number: 10405114
    Abstract: An active audio output detection system and method that automatically determines the type of audio output being used on an audio playback device. Embodiments of the system and method include playing back audio content on the audio playback device (such as a mobile phone) and capturing sound during playback using an audio capture device (such as a microphone). The captured sound is analyzed to determine whether the audio playing back on the audio playback device is contained therein. If the captured sound matches the audio playing back on the audio playback device, then the active audio output is a loudspeaker. On the other hand, if the captured sound does not match the audio playing back on the audio playback device, then the active audio output is headphones.

  • Patent number: 10405120
    Abstract: An audio object including audio content and object metadata is received. The object metadata indicates an object spatial position of the audio object to be rendered by audio speakers in a playback environment. Based on the object spatial position and source spatial positions of the audio speakers, initial gain values for the audio speakers are determined. The initial gain values can be used to select a set of audio speakers from among the audio speakers. Based on the object spatial position and a set of source spatial positions at which the set of audio speakers are respectively located in the playback environment, a set of non-negative optimized gain values for the set of audio speakers is determined. The audio object at the object spatial position is rendered with the set of optimized gain values for the set of audio speakers.
