Audio processors as a learning tool for basic acoustics

Audio processors like Audacity provide a ‘‘hear-and-see’’ learning tool for basic acoustics, combining sound and image. Activities designed as laboratory experiments with PC (even at home!) have been already successfully implemented, for example, about the dependence of timbre and acoustic spectrum, of pitch and frequency, and of loudness and amplitude. 2009 Wiley Periodicals, Inc.

Signal Processing, Acoustics, and Psychoacoustics for High Quality Desktop Audio

Integrated media workstations are increasingly being used for creating, editing, and monitoring sound that is associated with video or computer-generated images. While the requirements for high quality reproduction in large-scale systems are well understood, these have not yet been adequately translated to the workstation environment. In this paper we discuss several factors that pertain to hig...

Audio-visual Virtual Reality System for Room Acoustics

We present an audio-visual Virtual Reality display system for simulated sound fields. In addition to the room acoustic simulation by means of phonon tracing and finite element method this system includes the stereoscopic visualization of simulation results using a 3D back projection system as well as auralization by use of a professional sound equipment. For auralization purposes we develop a s...
