A data processing method includes acquiring video frame data including one or more video frames and audio data of a video, and determining position attribute information of a target object in the acquired one or more video frames, the target object being associated with the audio data. The method also includes acquiring a channel encoding parameter associated with the position attribute information, and performing azimuth enhancement processing on the audio data according to the channel encoding parameter to obtain enhanced audio data. Apparatus and non-transitory computer-readable storage medium counterpart embodiments are also contemplated.

A method performed by a programmed processor of an audio system, the method includes receiving a sound track that has a track length, producing a binaural audio version of a sound track, the binaural audio version having an extended track length performing a fading operation upon the binaural audio version to gradually reduce a signal level of the binaural audio version to below a signal threshold level at a time along the extended track length that corresponds to an end time of the track length of the sound track; and storing the binaural audio version having the track length of the sound track in memory for later transmission to an audio playback device for driving one or more speakers.

A system for rotating sound or selective listening to sound provides for the ability of the apparent direction of sound sources in a listening environment to remain in consistent orientations in space despite rotations of the microphones used to capture the sound and despite rotations of the head of the listener, even when wearing headphones. Modules are provided in the system to distinguish the sound sources and their apparent directions, as well as to optionally rotate the sound sources in response to detected rotations of the listener's head and/or detected rotations of the microphones.

An apparatus for optimizing a binaural beat according to an embodiment of the present invention includes: a binaural beat generator that generates a binaural beat; and a binaural beat controller that optimizes the binaural beat in consideration of a hearing state of left and right ears of a listener. A method for optimizing a binaural beat according to an embodiment of the present invention includes: generating a binaural beat; and optimizing the binaural beat in consideration of a hearing state of left and right ears of a listener.

A method for processing an audio signal and an electronic device, relate to the field of audio and video technology. The method includes: detecting beat information of the audio signal; and obtaining virtual surround sound for the audio signal by performing a convolution operation on a head-related transfer function and the audio signal based on the beat information of the audio signal.

Systems and methods for rendering audio signals are disclosed. In some embodiments, a method may receive an input signal including a first portion and the second portion. A first processing stage comprising a first filter is applied to the first portion to generate a first filtered signal. A second processing stage comprising a second filter is applied to the first portion to generate a second filtered signal. A third processing stage comprising a third filter is applied to the second portion to generate a third filtered signal. A fourth processing stage comprising a fourth filter is applied to the second portion to generate a fourth filtered signal. A first output signal is determined based on a sum of the first filtered signal and the third filtered signal. A second output signal is determined based on a sum of the second filtered signal and the fourth filtered signal. The first output signal is presented to a first ear of a user of a virtual environment, and the second output signal is presented to the second ear of the user. The first portion of the input signal corresponds to a first location in the virtual environment, and the second portion of the input signal corresponds to a second location in the virtual environment.

Systems and methods for using auditorily-induced vection (AIV) to enhance a person's attitude awareness are provided herein. In at least one embodiment, an auditory object is projected based on the orientation of the person or a vehicle and the projected auditory is provided to the person. By projecting the auditory object, the attitude of the person or the vehicle can be conveyed to the person to enhance the person's attitude awareness.

Methods and apparatus assist listeners in distinguishing between electronically generated binaural sound and physical environment sound while the listener wears a wearable electronic device that provides the binaural sound to the listener. The wearable electronic device generates a visual alert or audio alert when the electronically generated binaural sound occurs.

This specification describes an apparatus for controlling audio output. The apparatus provides first and a second audio components for output to first and second audio transducers of a wearable device, determine a proximity between the wearable device and a third audio transducer and determining a first or second state of the first and second audio transducers, and controlling output of at least one of the first and second audio components based on the determined proximity and the state of the first and second transducers. Responsive the proximity being under a threshold and the state of the first transducer being in a first state whilst the second transducer is in a second state, the apparatus causes output of the audio component associated with the second state transducer to be transferred to the third audio transducer whilst continuing to output the audio component associated with the first state transducer to said transducer.

A method and system for facilitating enhanced perception of ambiance soundstage and imaging as well as frequency and phase response linearization in audio devices is provided. The method includes receiving measurement data from an omnidirectional microphone and linearizing the data, both in the amplitude and time domains, using digital signal processing. The method also includes a crossfeed algorithm designed to emulate sound propagation from speakers.
