“Give me happy pop songs in C major and with a fast tempo”: A vocal assistant for content-based queries to online music repositories

This paper presents an Internet of Musical Things system devised to support recreational music-making, improvisation, composition, and music learning via vocal queries to an online music repository. The system involves a commercial voice-based interface and the Jamendo cloud-based repository of Creative Commons music content. Thanks to the system the user can query the Jamendo music repository by six content-based features and each combination thereof: mood, genre, tempo, chords, key and tuning. Such queries differ from the conventional methods for music retrieval, which are based on the piece's title and the artist's name. These features were identified following a survey with 112 musicians, which preliminary validated the concept underlying the proposed system. A user study with 20 musicians showed that the system was deemed usable, able to provide a satisfactory user experience, and useful in a variety of musical activities. Differences in the participants’ needs were identified, which highlighted the need for personalization mechanisms based on the expertise level of the user. Importantly, the system was seen as a concrete solution to physical encumbrances that arise from the concurrent use of the instrument and devices providing interactive media resources. Finally, the system offers benefits to visually-impaired musicians

Mechanical mode engineering with orthotropic metamaterial membranes

Metamaterials are structures engineered at a small scale with respect to the wavelength of the excitations they interact with. These structures behave as artificial materials whose properties can be chosen by design, mocking and even outperforming natural materials and making them the quintessential tool for manipulation of wave systems. In this Letter we show how the acoustic properties of a silicon nitride membrane can be affected by nanopatterning. The degree of asymmetry in the pattern geometry induces an artificial anisotropic elasticity, resulting in the splitting of otherwise degenerate mechanical modes. The artificial material we introduce has a maximum Ledbetter-Migliori anisotropy of 1.568, favorably comparing to most bulk natural crystals. With an additional freedom in defining arbitrary asymmetry axes by pattern rotation, our approach can be useful for fundamental investigation of material properties as well as for devising improved sensors of light, mass or acceleration based on micromechanical resonators

Interferometric control of absorption in thin plasmonic metamaterials: General two port theory and broadband operation

In order to extend the Coherent Perfect Absorption (CPA) phenomenology to broadband operation, the interferometric control of absorption is investigated in two-port systems without port permutation symmetry. Starting from the two-port theory of CPA treated within the Scattering Matrix formalism, we demonstrate that for all linear two-port systems with reciprocity the absorption is represented by an ellipse as function of the relative phase and intensity of the two input beams, and it is uniquely determined by the device single-beam reflectance and transmittance, and by the dephasing of the output beams. The basic properties of the phenomenon in systems without port permutation symmetry show that CPA conditions can still be found in such asymmetric devices, while the asymmetry can be beneficial for broadband operation. As experimental proof, we performed transmission measurements on a metal-semiconductor metamaterial, employing a Mach-Zehnder interferometer. The experimental results clearly evidence the elliptical feature of absorption and trace a route towards broadband operation
