摘要： A method implemented in an audio synthesis device for synthesizing an audio signal is provided. The method includes determining a first plurality of harmonics based on a sinusoidal oscillator, at least two of the first plurality of harmonics being calculated in parallel, scaling the first plurality of harmonics according to a scaling parameter, determining a first sum of the first plurality of scaled harmonics to generate a first sample of the plurality of samples, determining a second plurality of harmonics based on the sinusoidal oscillator, at least two of the second plurality of harmonics being calculated in parallel, scaling the second plurality of harmonics according to the scaling parameter, determining a second sum of the second plurality of scaled harmonics to generate a second sample of the plurality of samples, and causing playback, on the speaker, of at least the first sample and the second sample.

摘要： Systems and methods for generating an engine vibration simulated signal, which is an acceleration sensor simulated signal, generate the signal based on current driving-related information, without mounting an acceleration sensor on an engine, such that a virtual engine sound can be controlled to be output naturally according to an engine output torque of a vehicle.

摘要： An audio generation device for brain dynamics audio stimulation includes an audio playing device, a brainwave capturing device, and a computing device. The audio playing device sequentially outputs multiple audio signals to give a subject sound stimulation with various audio frequencies. The brainwave capturing device captures brainwave signals from the subject. The computing device analyzes the pairwise dynamics correlation of the channel signals of the brainwave signal to obtain the correlation of the transfer direction associativity in response to the brain stimulation, synthesizes a test audio according to at least one audio frequency corresponding to a target channel, and makes the test audio as an output audio when the target channel belongs to the high-correlation response channel of the brainwave signal that the subject generates in response to listen to the test audio. An audio generation method for brain dynamics audio stimulation is also provided.

摘要： Systems and methods to increase environment awareness in remote driving applications may include a vehicle having an imaging device and a teleoperator station in communication with each other via a network. For example, audio data may be received from the vehicle and processed to identify known sounds associated with unseen objects in the environment. In addition, imaging data may be received from the vehicle and processed to identify known but unheard objects in the environment. Based on the identified sounds and/or objects, visualizations of the objects may be generated and presented to a teleoperator, and sounds associated with the objects may be amplified, synthesized, and/or emitted to the teleoperator to increase environment awareness.

摘要： Techniques (methods and devices) for audio content serving and creation based on modulation characteristics are disclosed. The techniques include receiving user-associated data related to a user; determining one or more desired modulation characteristic values based on the user-associated data; obtaining a set of one or more target audio tracks, wherein each target audio track represents at least one or more modulation characteristic values; comparing the desired modulation characteristic values with the modulation characteristic values of at least one target audio track from the set of one or more target audio tracks; selecting a target audio track from the at least one target audio track based on the comparing, wherein the modulation characteristic values of the target audio track substantially match the desired modulation characteristic values; and playing the target audio track.

摘要： A virtual engine sound generating system and method involves generating a virtual engine sound with a Shepard tone by superposing sine waves separated by octaves, which causes an auditory illusion as if an infinite musical scale is played, and gives a driver a feeling that engine power continually increases.

摘要： Disclosed is a sound design method for overcoming sense of difference when there is no virtual sound while an auto cruise control is activated. The method includes determining whether an accelerator pedal is actuated; upon determining that the accelerator pedal is not actuated, determining whether an auto cruise control system is operating; upon determining whether the auto cruise control system is operating, classifying a vehicle speed-based order component from a driving sound; and reproducing a speed sensitive virtual sound based on the classified vehicle speed-based order component.
