PENGEMBANGAN MEDIA PEMBELAJARAN BERBASIS MULTIMEDIA INTERAKTIF UNTUK MENINGKATKAN KEMAMPUAN MELAKUKAN SHOLAT SISWA SEKOLAH DASAR

The research aims to see how the influence of developing interactive multimedia-based learning media is to improve the ability to pray. The focus of research for fourth-grade students at SD Negeri 115525 Sigambal. The material to be packaged is the primary material and the core of learning to pray. The packaged components are sound audio, visualization of images, videos, animations, and sentences or text. The teaching media section consists of introductions, media information assistance, teaching materials, assignments, and exam questions. The media is equipped with a button that makes the media move between the sheets of teaching media. Research methods R&D or Research and Development. Field test with the Guttman Scale for smooth scoring. The Guttman scale will generate action with a definite value, divided into two choices, yes or no. The effect of developing interactive multimedia-based learning media can improve the ability to pray for fourth-grade students at SD Negeri 115525 Sigambal has been recognized as eligible to be a teaching medium for grade four elementary school students at SD Negeri 115525 Sigambal

A New Timbre Visualization Technique Based on Semantic Descriptors

This article introduces the concept of Sound Signature audio visualization, a new form of amplitude waveform that also visualizes perceptually salient spectral features and their evolution over time. A brief review of existing research into timbre description and visualization is given. This is followed by an in-depth description of the algorithm. Rationale is given for the various visual mappings with reference to existing literature. The results of an online subjective evaluation survey are reported and discussed. The survey examined user preferences for the visual mappings used in Sound Signature visualizations. Results show a preference for inverse mapping of spectral centroid to the first component of the hue, saturation, value (HSV) color space.

Some Principles of Visual Design for Computer Music

This article presents observations pertaining to expressive visual design for computer music, focusing in particular on real-time integration of graphics and audio. The author describes specific projects as examples supporting a set of design principles that range from “user-oriented” to “aesthetic” and other observations. Examples include audio visualization, game-like interfaces, and mobile musical instruments.
