Microphone arrays are usually employed for spatial audio recordings and analysis. This requires converting the raw signals of the capsules into a 3d audio format, e.g., a spherical harmonics expansion. For processing such conversion, namely beamforming, it is necessary to know the complex response of each microphone of the array for many directions-of-Arrival of the sound waves. This information constitutes the spatial response and describes how the wave fronts are diffracted by the surface of the array. Beyond the experimental, numerical, or theoretical method employed to get the spatial response, the shape of the array and the number of capsules, the choice of the directions-of-Arrival of the sound waves is always critical. On one side, to maximize the spatial information and so the performance, on the other side to reduce the number of directions, and so the measurement or calculation time. The paper analyzes the problem of choosing an optimal geometry for obtaining the spatial response of a microphone array. it will be shown that spherical design, or T-design, allows maximizing the spatial information with the minimum amount of testing directions. Numerical and theoretical methods have been employed for characterizing two microphone arrays, a spherical and a non-spherical one. in both cases, Ambisonics format for spatial audio has been employed.

Realistic auralizations of sound fields have an enormous potential for many engineering, entertainment, and architecture applications. The research and development on immersive and 3d audio has been providing new solutions both for the capture and for the reproduction of sound fields and acoustical environments. This paper presents a study to assess the capacity of a recording and reproduction system to preserve the spatial properties of real 3d sound fields. The system is based on the audio capture through a 64-microphone spherical array and reproduction through a spherical layout of loudspeakers installed inside an anechoic chamber, making use of ambisonics format. A methodology to perform an objective analysis was proposed, using the spherical array of microphones as the listener of the implemented reproduction system, recording sound fields generated by the system itself or by external loudspeakers, and comparing audio signals before and after the processing by the system. Subjective listening tests were also performed by a set of individuals, evaluating the immersive experience provided by the system reproducing sound fields captured with the array in different environments: a car cabin, an aero generators farm, a tennis court, and a concert hall. Objective tests attested the system capacity to reproduce the location of the sound source adequately, although without a uniform source location separation along the different positions. The subjective listening tests revealed that the system provides different levels of accuracy on the perceived positions of the sound sources depending on their original positions and on the sound type. The perception of the overall original acoustic environments is achieved successfully, allowing the listeners to feel transported to the all the original places where the 3d audio capture took place.

Sound field reproduction methods based on numerical optimization, which aim to minimize the error between synthesized and desired sound fields, are useful in many practical scenarios because of their flexibility in the array geometry of loudspeakers. However, the reproduction performance of these methods in a practical environment has not been sufficiently investigated. We evaluate weighted mode matching, which is a sound field reproduction method based on the spherical wavefunction expansion of the sound field, in comparison with conventional pressure matching. We also introduce a method of infinite-dimensional harmonic analysis for estimating the expansion coefficients of the sound field from microphone measurements. Experimental results indicated that weighted mode matching using the expansion coefficients of the transfer functions estimated by the infinite-dimensional harmonic analysis outperforms conventional pressure matching, especially when the number of microphones is small.

Lossius et. al introduced the distance-based amplitude panning algorithm, or dBAP, to enable flexibility of loudspeaker placement in artistic and scientific contexts. The algorithm allows for arbitrary loudspeaker locations in a 2d plane so that a virtual sound source may navigate the 2d space. The gains for each speaker are calculated as a function of the source's distance to each loudspeaker, thus creating a sound field. This gives the listener the impression of a source moving through the field of loudspeakers. This paper introduces a heuristically developed robust variation of dBAP that corrects for faulty assumptions in the implementation of Lossius. Specifically, this paper develops a method for working with sound sources outside the field of loudspeakers in which the Lossius version produces distorted aural impressions and wildly undulating amplitudes caused by spatial discontinuities in the gains of the various loudspeakers. in smoothing the spatial impression of the virtual source, we are also able to eliminate the calculation of the convex hull entirely, a necessary component of the original implementation. This significantly simplifies and reduces the calculations required for any space in either two or three dimensions.

Modern streaming services dominate the way people consume music. While immediate access to music is certainly convenient, such services do not provide users with much control over their listening experience, other than simple volume settings or more rarely via equalization. in this work, we enhance the music listening experience by combining deep musical source separation with online binaural spatial audio remixing of the separated sources. We introduce YouMixit(1), an end-to-end web application that allows users to separate music downloaded from You Tube into four different audio stems (vocals, bass, drums, and accompaniment) and interactively manipulate the 3d position and volume settings of each stem within the simulated listening space. Our interface introduces novel degrees of control allowing users to create personalized musical mixtures.

Music composition - much like every construction of a work of art - can be understood as a sequence of decisions made by the composer or artist. The specific work thus embodies one out of many possible variations. Especially in sonic art and electroacoustic music, where spatial-audio playback systems have been employed since the early days of multi-channel sound reproduction, the distribution of auditory objects in space continues to be an important step in the creative process - as a matter of composition and in stark contrast to more popular musical genres that are produced in stereo, where the spatial distribution is considered a rather technical issue. The aim of the present work is to gain an understanding of the relevance of incorporating spatial configuration as an artistic device in music composition. A listening test was conducted to investigate the perception of certain spatial configurations of sonic elements dependent of spatial complexity and the sonic material.

Many and great efforts have been put into creating anechoic recordings of symphony orchestras, opera arias, solo instruments, speech and etc. However, chamber music, a typical music formation is poorly represented in the available anechoic material library. This is especially relevant in the context of small concert halls, where typically the most common form of concert would be of chamber music. With this need for material in mind, short excerpts of each movement of Haydn's string quartet op. 76 n.1 have been recorded in an anechoic chamber. The recordings have been conducted with individual instruments with an array of 12 studio microphones positioned evenly around the musician. This paper reports on the methods, technical aspects and difficulties faced in producing such recording, as well as the post-processing required to achieve a realistic and usable performance of a string quartet. The finalized audio files will be made freely available for use in academic research.

in this paper, we present a method to auralize acoustic scattering and occlusion of a single rigid sphere with parametric filters and neural networks to provide fast processing and estimation of parameters. The filter parameters are estimated using neural networks based on the geometric parameters of the simulated scene, e.g., relative receiver position and size of the rigid spherical scatterer. The modeling differentiates an unoccluded and an occluded source-receiver path, for which different filter structures were used. in contrast to simulating occlusion and scattering numerically or analytically methods, the proposed approach provides rendering with low computational load making it suitable for real-time auralization in virtual reality. The presented method provides a good fit for modeling the acoustic effects of a rigid sphere. Further, a listening test was conducted, which resulted in plausible reproduction of the scattering and occlusion of a rigid sphere.

The acquisition of the spatio-temporal characteristics of a sound field over a large volume of space is experimentally challenging, as a large number of transducers is required to sample the sound field. Sound field reconstruction methods are a resourceful approach, as they enable the interpolation and extrapolation of the sound field from a limited number of observed data. in this study we examine the spatio-temporal and spatio-spectral reconstruction of the sound field in a room from distributed measurements of the sound pressure. Specifically, a variational Gaussian process regression model is formulated, using time-domain anisotropic kernels to reconstruct the direct sound and early reflections, and frequency-domain isotropic kernels for reconstructing the late reverberant field. The proposed methodology is compared experimentally to classical regression models based on plane wave decompositions, which are widely used in sound field reconstruction in enclosures due to their simplicity and accuracy.

The cinema Lux is one of the most relevant cinemas in Rome. it is located in the historical city center of the city, close to the Tevere river. The acoustics of the cinema Lux has been analyzed considering different approaches. First of all, monoaural acoustic parameters have been obtained following the iSO 3382-1 Standard;additionally, the binaural acoustic parameters have been obtained by employing a dummy head (Neumann KU 100). Moreover, the B-Format impulse responses (iRs) have been utilized for calculating the Lateral Fraction (LF) and the Lateral Efficiency (LE). The 3d acoustic information has been gathered by employing a 32-channel spherical microphone array, in combination with a 360 degrees camera, in order to reconstruct the reflection paths bouncing inside the screen. This paper deals with the main acoustic parameters by comparing the results with other cinemas of similar characteristics.
