DETECTION AND CLASSIFICATION OF AUDIO EVENTS IN GAMING SYSTEMS
A system that incorporates the subject disclosure may include, for example, a gaming system that cooperates with a graphical user interface to enable user modification and enhancement of one or more audio streams associated with the gaming system. In embodiments, the audio streams may include a game audio stream, a chat audio stream of conversation among players of a video game, and a microphone audio stream of a player of the video game. Additional embodiments are disclosed.
AUDIO SIGNAL PROCESSING METHOD AND AUDIO SIGNAL PROCESSING APPARATUS
An audio signal processing method is provided. The method separates a left and a right channel audio signal to a center-left and center-right channel audio signals, and a side-left and side-right channel audio signals, and processes the center and side channel audio signals by a Head Related Transfer Function (HRTF) so as to simulate the audio signals into several audio source positions related to a user, then synthesizes the processed audio signals into dual channel audio signals according to the user's hearing characteristics by a frequency compensation process. The invention further provides an audio signal processing apparatus to perform the audio signal processing method.
SYSTEM AND METHOD FOR HEADPHONE EQUALIZATION AND ROOM ADJUSTMENT FOR BINAURAL PLAYBACK IN AUGMENTED REALITY
A system is provided. The system includes an analyzer for determining a plurality of binaural room impulse responses, and a loudspeaker signal generator for generating at least two loudspeaker signals depending on the plurality of binaural room impulse responses and depending on the audio source signal of at least one audio source. The analyzer is configured to determine the plurality of the binaural room impulse responses such that each of the plurality of the binaural room impulse responses considers an effect that results from a headphone being worn by a user.
Audio encoder, audio decoder, methods and computer program using jointly encoded residual signals
An audio decoder for providing at least four audio channel signals on the basis of an encoded representation is configured to provide a first residual signal and a second residual signal on the basis of a jointly encoded representation of the first residual signal and of the second residual signal using a multi-channel decoding. The audio decoder is configured to provide a first audio channel signal and a second audio channel signal on the basis of a first downmix signal and the first residual signal using a residual-signal-assisted multi-channel decoding. The audio decoder is configured to provide a third audio channel signal and a fourth audio channel signal on the basis of a second downmix signal and the second residual signal using a residual-signal-assisted multi-channel decoding. An audio encoder is based on corresponding considerations.
Method for generating and outputting an acoustic multichannel signal
Method for generating and outputting an acoustic multichannel signal, comprising the steps of: supplying a stereo signal (S), splitting the supplied stereo signal (S) into a plurality of perception-direction-dependent acoustic signal components (S.1-S.5), generating an acoustic multichannel signal by mixing each perception-direction-dependent acoustic signal component (S.1-S.5) onto an output channel (4.1-4.12) of an acoustic output apparatus (4) that comprises a plurality of, in particular more than two, acoustic output channels (4.1-4.12), outputting the generated multichannel signal over respective acoustic output channels (4.1-4.12) of the acoustic output apparatus (4).
Localizing binaural sound to objects
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.
System and method for rendering real-time spatial audio in virtual environment
A new real-time spatial audio rendering system includes a real-time spatial audio rendering computer software application adapted to run on a communication device. The application renders stereo audio from mono audio sources in a virtual room of a listener. The listener can be mobile. The stereo audio is rendered for each listener within the room. The real-time spatial audio rendering system has two different modes, with and without reverberation. Reverberation can provide the sense of the dimensions of the room, First, the anechoic processing module produces the anechoic stereo audio that provides the sense of direction and distance of spatial audio. When reverberation is desired, the reverberation processing module is also performed to provide the sense of the room's dimensions by the spatial audio.
6DOF Rendering of Microphone-Array Captured Audio For Locations Outside The Microphone-Arrays
An apparatus for generating a spatialized audio output based on a listener position, the apparatus including circuitry configured to: obtain two or more audio signal sets; obtain a listener position within an audio environment, wherein the audio environment includes one or more area having one or more inside and outside regions in relation to the respective audio signal set positions; obtain metadata based on a processing of the at least two audio signals; determine, for the listener position within an audio environment outside the inside region, a second listener position; determine modified metadata for the second listener position based on the metadata; determine at least two modified audio signals for the second listener position based on the at least two audio signals; determine spatial metadata for the listener position; and output the at least two modified audio signals and the spatial metadata.
Spatial audio parameters and associated spatial audio playback
An apparatus including at least one processor and at least one memory including a computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to: determine, for two or more microphone audio signals, at least one spatial audio parameter for providing spatial audio reproduction; determine at least one coherence parameter associated with a sound field based on the two or more microphone audio signals, such that another sound field is configured to be reproduced based on the at least one spatial audio parameter and the at least one coherence parameter.
CONTENT BASED SPATIAL REMIXING
A trained machine configured to input a stereo sound track and separate the stereo sound track into multiple N separated stereo audio signals respectively characterized by multiple N audio content classes. All stereo audio as input in the stereo sound track is included in the N separated stereo audio signals. A mixing module is configured to spatially localize symmetrically and without cross-talk, between left and right, the N separated stereo audio signals into multiple output channels. The output channels include respective mixtures of one or more of the N separated stereo audio signals. Gain is adjusted of the output channels into left and right binaural outputs to conserve summed levels of the N separated stereo audio signals distributed over the output channels.
