An illustrative audio processing system identifies an experience location with which an augmented reality presentation device is associated. The experience location is included within a multizone augmented reality space that is presented by the augmented reality presentation device. The audio processing system determines that the experience location is within both a first sound zone and a second sound zone of the multizone augmented reality space, and, based on the determining that the experience location is within both the first and second sound zones, generates a binaural audio stream for presentation by the augmented reality presentation device. The binaural audio stream includes an environmental audio component implemented by a mix of a first environmental audio stream associated with the first sound zone and a second environmental audio stream associated with the second sound zone. Corresponding methods and systems are also disclosed.

One embodiment provides a method comprising determining stimuli for simultaneously exciting a plurality of speakers within a spatial area. The method further comprises simultaneously exciting the plurality of speakers by providing the stimuli to the plurality of speakers at the same time for reproduction. The method further comprises recording, during the reproduction, one or more measurements of sound arriving at one or more microphones within the spatial area. The method further comprises simultaneously deconvolving a plurality of impulse responses of the plurality of speakers based on the stimuli and the one or more measurements.

A method, system, server and device are disclosed. According to one or more embodiments, a server is provided. A first audio track is received which includes first audio originating from a premises client at a premises location. A second audio track is received which includes second audio originating from a remote client. A first pan angle is determined for the first audio track and a second pan angle is determined for the second audio track. The second pan angle is different from the first pan angle. A stereo composite track is generated based on the first pan angle and the second pan angle, where the stereo composite track includes the first audio track and the second audio track.

Example embodiments may include one or more of receiving an electrical sound emission signal from a sound controller, interrupting reception of the electrical sound emission signal, by a sound emission interruption circuit connected to a sound emitter, and receiving an electrical ambient sound signal via a sound detection circuit, based on ambient sound sensed by the sound emitter when the reception of the electrical sound emission signal is interrupted by the sound emission interruption circuit.

In some embodiments, virtualization methods for generating a binaural signal in response to channels of a multi-channel audio signal, which apply a binaural room impulse response (BRIR) to each channel including by using at least one feedback delay network (FDN) to apply a common late reverberation to a downmix of the channels. In some embodiments, input signal channels are processed in a first processing path to apply to each channel a direct response and early reflection portion of a single-channel BRIR for the channel, and the downmix of the channels is processed in a second processing path including at least one FDN which applies the common late reverberation. Typically, the common late reverberation emulates collective macro attributes of late reverberation portions of at least some of the single-channel BRIRs. Other aspects are headphone virtualizers configured to perform any embodiment of the method.

A computer program product having a non-transitory computer-readable medium including computer program logic encoded thereon that, when performed on a surround sound audio system that is configured to render left front, right front, and center front audio signals, and also render left and right near-field binaurally-encoded audio signals, causes the surround sound audio system to develop the left and right near-field binaurally-encoded audio signals, and provide the left near-field binaurally-encoded audio signal to a left non-occluding near-field driver and provide the right near-field binaurally-encoded audio signal to a right non-occluding near-field driver.

A method and a system for instrument separating and reproducing for a mixture audio source is provided. The method and/or the system includes inputting selected music into an instrument separation model for extracting features therefrom, determining audio source signals of multiple channels for the separation of all instruments, each channel containing sound of one instrument, and transmitting the signals of the different channels to multiple speakers placed at designated positions for playing, which can reproduce or recreate an immersive sound field listening experience for users.

The present disclosure provides a method and system for voice enhancement. The method and system of the present disclosure may simultaneously perform signal processing of two paths on an input signal. The first path signal processing includes receiving an audio source input and performing dynamic loudness balancing on the audio source input based on a first gain control parameter. The second path signal processing includes: performing voice detection on the audio source input and calculating a detection confidence; and calculating a second gain control parameter based on the detection confidence. The first path signal processing and the second path signal processing may be synchronous or asynchronous. The method of the present disclosure also includes updating the first gain control parameter with the second gain control parameter calculated by a second processing path and performing the first path signal processing based on the updated first gain control parameter.

One or more embodiments include techniques for generating immersive audio for an acoustic system. The techniques include determining an apparent location associated with a portion of audio; calculating, for each speaker included in a plurality of speakers of the acoustic system, a perceptual distance between the speaker and the apparent location; selecting a subset of speakers included in the plurality of speakers based on the perceptual distances between the plurality of speakers and the apparent location; generating a set of filters based on the subset of speakers and one or more target characteristics of the acoustic system; and generating, for each speaker included in the subset of speakers, a speaker signal using one or more filters included in the set of filters.
