When two notes are played simultaneously they form a musical dyad. The sensation of pleasantness, or "consonance", of a dyad is likely driven by the harmonic relation of the frequency components of the combined spectrum of the two notes. Previous work has demonstrated a relation between individual preference for consonant over dissonant dyads, and the strength of neural temporal coding of the h...

We introduce the complete lifts of maps between (real and complex) Euclidean spaces and study their properties concerning holomorphicity, harmonicity and horizontal weakly conformality. As applications, we are able to use this concept to characterize holomorphic maps φ : C ⊃ U −→ C (Proposition 2.3) and to construct many new examples of harmonic morphisms (Theorem 3.3). Finally we show that the...

We evaluate a new filterbank structure, yielding the harmonic structure cepstral coefficients (HSCCs), on a mismatchedsession closed-set speaker classification task. The novelty of the filterbank lies in its averaging of energy at frequencies related by harmonicity rather than by adjacency. Improvements are presented which achieve a 37%rel reduction in error rate under these conditions. The imp...

We describe a new model of CASA labelling which assigns to each time-frequency region a probability "clean" enough to feed a multistream recogniser only adapted to clean data. This labelling process is based on the harmonicity of the speech. The probability is evaluated according to a SNR-feature mapping and the choice of a SNR decision threshold. This allows an extension of a previous method [...

Five experiments were conducted to study the acoustic attributes that enable the accurate identification and localization of rudimentary spatial warning sounds. In each experiment, two sounds were played simultaneously over loudspeakers at various azimuths and elevations. The stimuli consisted of pure tone complexes with a 13 kHz bandwidth. The fundamental frequencies, the amplitude modulation ...

Data Jockey is a free and open-source digital DJ software system that allows users to mix several audio works based on content features, such as average brightness and average harmonicity, while syncing the works to a common clock. This software allows users to search through an audio database using audio content descriptors as search criteria. These features help users explore their ever-expan...

The dynamics of chiral nuclei is investigated for the first time with time-dependent and tilted axis cranking covariant density functional theories on a three-dimensional space lattice in microscopic self-consistent way. experimental energies two pairs doublet bands $^{135}$Nd are well reproduced without any adjustable parameters beyond well-defined functional. A novel mechanism, i.e., precessi...

A new method for estimating the fundamental frequencies of concurrent musical sounds is described. The method is based on an iterative approach, where the fundamental frequency of the most prominent sound is estimated, the sound is subtracted from the mixture, and the process is repeated for the residual signal. For the estimation stage, an algorithm is proposed which utilizes the frequency rel...

We discuss the harmonicity of horizontally conformal maps and their relations with the spectrum of the Laplacian. We prove that if φ : M → N is a horizontally conformal map such that the tension field is divergence free, then φ is harmonic. Furthermore, if N is noncompact, then φ must be constant. Also we show that the projection of a warped product manifold onto the first component is harmonic...

In this article, we present some results concerning the harmonicity on tangent bundle equipped with vertical rescaled metric. We establish necessary and sufficient conditions under which a vector field is harmonic respect to metric construct examples of fields. also study along map between Riemannian manifolds, target manifold its bundle. Next discuss composition projection from into another ma...
