This study investigates the human ability to perceive biological movements through friction sounds produced by drawings and, furthermore, recover drawn shapes from generated.In a first experiment, sounds, real-time synthesized and modulated velocity profile of drawing gesture, revealed that subjects associated movement those whose timbre variations were generated profiles following 1/3 power law.This finding demonstrates can adequately inform about if their acoustic characteristics are in...

Sleep deprivation has an ever-increasing impact on individuals and societies. Yet, to date, there is no quick objective test for sleep deprivation. Here, we used automated acoustic analyses of the voice detect Building current machine-learning approaches, focused interpretability by introducing two novel ideas: use a fully generic auditory representation as input feature space, combined with interpretation technique based reverse correlation. The consisted spectro-temporal modulation...

Timbre provides an important cue to identify musical instruments. Many timbral attributes covary with other parameters like pitch. This study explores listeners' ability construct categories of instrumental sound sources from sounds that vary in Nonmusicians identified 11 instruments the woodwind, brass, percussion, and plucked bowed string families. In experiment 1, they were trained playing a pitch C4, experiments 2 3, five-tone sequence (F#3–F#4), exposing them way timbre varies...

The Temporal Voice Areas (TVAs) respond more strongly to speech sounds than non-speech vocal sounds, but does this make them "Speech" Areas? We provide a perspective on issue by combining univariate, multivariate, and representational similarity analyses of fMRI activations balanced set sounds. find that while activate the TVAs which is likely related their larger temporal modulations in syllabic rate, they do not appear additional areas nor are segregated from when higher activation...

Abstract In this article, we propose a control strategy for synthesized continuous-interaction sounds. The framework of our research is based on the action–object paradigm that describes sound as result an action object and presumes existence invariants (i.e., perceptually relevant signal morphologies carry information about action's or object's attributes). Auditory cues are investigated here evocations rubbing, scratching, rolling interactions. A generic sound-synthesis model simulates...

Timbre perception and auditory grouping principles can provide a theoretical basis for aspects of orchestration. In Experiment 1, 36 excerpts contained two streams 12 one stream as determined by music analysts. Streams—the perceptual connecting successive events—comprised either single instruments or blended combinations from the same different families. Musicians nonmusicians rated degree segregation perceived in excerpts. Heterogeneous instrument between yielded greater than did...

The ability of a listener to recognize sound sources, and in particular musical instruments from the sounds they produce, raises question determining acoustical information used achieve such task. It is now well known that shapes temporal spectral envelopes are crucial recognition instrument. More recently, Modulation Power Spectra (MPS) have been shown be representation potentially explains perception instrument sounds. Nevertheless, which specific regions this characterize still open. An...

Abstract What is the function of auditory hemispheric asymmetry? We propose that identification sound sources relies on asymmetric processing two complementary and perceptually relevant acoustic invariants: actions objects. In a large dataset environmental sounds, we observed temporal spectral modulations display only weak covariation. then synthesized stimuli by simulating various (frictions) occurring different objects (solid surfaces). Behaviorally, discrimination modulations, while...

Abstract What is the function of auditory hemispheric asymmetry? We propose that identification sound sources relies on two complementary and perceptually relevant acoustic invariants — actions objects are processed asymmetrically sufficient to model categorize any sound. observed environmental sounds an independent combination purely temporal spectral modulations. Behaviorally, discrimination relied modulations, while Functional magnetic resonance imaging data showed respectively decoded in...

The perception and production of biological movements is characterized by the 1/3 power law, a relation linking curvature velocity an intended action. In particular, motions are perceived reproduced distorted when their kinematics deviate from this law. Whereas most studies dealing with perceptual-motor focused on visual or kinaesthetic modalities in unimodal context, paper we show that auditory dynamics strikingly biases visuomotor processes. Biologically consistent inconsistent circular...

Modulation Power Spectra include dimensions of spectral and temporal modulation that contribute significantly to the perception musical instrument timbres. Nevertheless, it remains unknown whether each instrument's identity is characterized by specific regions in this representation. A recognition task was applied tuba, trombone, cello, saxophone, clarinet sounds resynthesized with filtered spectrotemporal modulations. The most relevant parts representation for identification were determined...

Abstract The cerebral processing of voice information is known to engage, in human as well non-human primates, “temporal areas” (TVAs) that respond preferentially conspecific vocalizations. However, how represented by neuronal populations these areas, particularly speaker identity information, remains poorly understood. Here, we used a deep neural network (DNN) generate high-level, small-dimension representational space for identity—the ‘voice latent space’ (VLS)—and examined its linear...

Many animals can extract useful information from the vocalizations of other species. Neuroimaging studies have evidenced areas sensitive to conspecific in cerebral cortex primates, but how these process heterospecific remains unclear. Using fMRI-guided electrophysiology, we recorded spiking activity individual neurons anterior temporal voice patches two macaques while they listened complex sounds including several In addition cells selective for macaque vocalizations, identified an...

Musical instrument timbre has been intensively investigated through dissimilarity rating tasks. It is now well known that audio descriptors such as attack time and spectral centroid, among others, account for the dimensions of spaces underlying these ratings. Nevertheless, it remains very difficult to reproduce perceptual judgments from distances computed on acoustical representations waveform or spectrogram. Interestingly, biologically inspired based spectrotemporal modulation spectra...

We combine perceptual research and acoustic analysis to probe the messy, pluralistic world of musical semantics, focusing on sound mass music. Composers scholars describe with many semantic associations. designed an experiment evaluate what extent these associations are experienced by other listeners. Thirty-eight participants heard 40 excerpts music related contemporary genres rated them along batteries scales. Participants also described their rating strategies for some categories. A...
