A system and method for generating a virtual soundstage in a listening environment having a compact speaker array centrally positioned in a listening environment. A listener is sitting offset from the speaker array and the virtual soundstage is generated in front of a listener. A signal processing unit is configured to receive an incoming audio signal, to process left and right channel signals of the incoming audio signal to generate a null, and to steer the null toward one ear of a listener thereby generating a virtual sound source that is offset from the center of the listening environment. Virtual sound sources are generated in front of, to the left of, and to the right of the listener.

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.

An electronic device identifies a location of a physical object that is away from a listener. The electronic device convolves sound so the sound externally localizes as binaural sound to the physical object. The sound plays to the listener through earphones so the listener hears the sound as emanating from the physical object.

An electronic device receives, from a user, a restriction that restricts how sound of a digital asset plays to non-owners of the digital asset that is tokenized as a non-fungible token (NFT). One or more electronic devices tokenize the digital asset as the NFT on a blockchain that stores the restriction how the sound of the digital asset plays to the non-owners of the NFT.

Example techniques relate to audio generation in a media playback system. Based on one or more first functions and first characteristics of an area, the system may generate first audio that includes a first audio signal and a second audio signal. The system provides the first audio signal to at least one first audio driver and the second audio signal to at least one second audio driver, thereby causing a first playback device and a second playback device to play back the first audio synchronously. The system receives second characteristics of the area and based on one or more second functions and the second characteristics, generates second audio comprising a third audio signal and a fourth audio signal. The system provides the third audio signal to the at least one first audio driver and the fourth audio signal to the at least one second audio driver.

The invention discloses an electroencephalogram-controlled video input and auditory display blind guiding apparatus and method. The apparatus includes a video acquisition module, an electroencephalogram acquisition module, a processor and an audio playback module. The video acquisition module is connected to the processor, the electroencephalogram module is connected to the processor and configured to acquire an electroencephalogram signal, the audio playback module is connected to the processor, and the processor is separately connected to the video acquisition module, the electroencephalogram acquisition module and the audio playback module.
