USING MICROPHONE ARRAYS to RECONSTRUCT MOVING SOUND SOURCES for AURALIZATION 1 Introduction
USING MICROPHONE ARRAYS TO RECONSTRUCT MOVING SOUND SOURCES FOR AURALIZATION Fanyu Meng, Michael Vorlaender Institute of Technical Acoustics, RWTH Aachen University, Germany {[email protected]) Abstract Microphone arrays are widely used for sound source characterization as well as for moving sound sources. Beamforming is one of the post processing methods to localize sound sources based on microphone array in order to create a color map (the so-called “acoustic camera”). The beamformer response lies on the array pattern, which is influenced by the array shape. Irregular arrays are able to avoid the spatial aliasing which causes grating lobes and degrades array performance to find the spatial positions of sources. With precise characteristics from the beamformer output, the sources can be reconstructed regarding not only spatial distribution but also spectra. Therefore, spectral modeling methods, e.g. spectral modeling synthesis (SMS) can be combined to the previous results to obtain source signals for auralization. In this paper, we design a spiral microphone array to obtain a specific frequency range and resolution. Besides, an unequal-spacing rectangular array is developed as well to compare the performance with the spiral array. Since the second array is separable, Kronecker Array Transform (KAT) can be used to accelerate the beamforming calculation. The beamforming output can be optimized by using deconvolution approach to remove the array response function which is convolved with source signals. With the reconstructed source spectrum generated from the deconvolved beamforming output, the source signal is synthesized separately from tonal and broadband components. Keywords: auralization, synthesizer, microphone arrays, beamforming, SMS PACS no. -
The 1-Bit Instrument: the Fundamentals of 1-Bit Synthesis
BLAKE TROISE The 1-Bit Instrument The Fundamentals of 1-Bit Synthesis, Their Implementational Implications, and Instrumental Possibilities ABSTRACT The 1-bit sonic environment (perhaps most famously musically employed on the ZX Spectrum) is defined by extreme limitation. Yet, belying these restrictions, there is a surprisingly expressive instrumental versatility. This article explores the theory behind the primary, idiosyncratically 1-bit techniques available to the composer-programmer, those that are essential when designing “instruments” in 1-bit environments. These techniques include pulse width modulation for timbral manipulation and means of generating virtual polyph- ony in software, such as the pin pulse and pulse interleaving techniques. These methodologies are considered in respect to their compositional implications and instrumental applications. KEYWORDS chiptune, 1-bit, one-bit, ZX Spectrum, pulse pin method, pulse interleaving, timbre, polyphony, history 2020 18 May on guest by http://online.ucpress.edu/jsmg/article-pdf/1/1/44/378624/jsmg_1_1_44.pdf from Downloaded INTRODUCTION As unquestionably evident from the chipmusic scene, it is an understatement to say that there is a lot one can do with simple square waves. One-bit music, generally considered a subdivision of chipmusic,1 takes this one step further: it is the music of a single square wave. The only operation possible in a -bit environment is the variation of amplitude over time, where amplitude is quantized to two states: high or low, on or off. As such, it may seem in- tuitively impossible to achieve traditionally simple musical operations such as polyphony and dynamic control within a -bit environment. Despite these restrictions, the unique tech- niques and auditory tricks of contemporary -bit practice exploit the limits of human per- ception. -
The History of Computer Language Selection
The History of Computer Language Selection Kevin R. Parker College of Business, Idaho State University, Pocatello, Idaho USA [email protected] Bill Davey School of Business Information Technology, RMIT University, Melbourne, Australia [email protected] Abstract: This examines the history of computer language choice for both industry use and university programming courses. The study considers events in two developed countries and reveals themes that may be common in the language selection history of other developed nations. History shows a set of recurring problems for those involved in choosing languages. This study shows that those involved in the selection process can be informed by history when making those decisions. Keywords: selection of programming languages, pragmatic approach to selection, pedagogical approach to selection. 1. Introduction The history of computing is often expressed in terms of significant hardware developments. Both the United States and Australia made early contributions in computing. Many trace the dawn of the history of programmable computers to Eckert and Mauchly’s departure from the ENIAC project to start the Eckert-Mauchly Computer Corporation. In Australia, the history of programmable computers starts with CSIRAC, the fourth programmable computer in the world that ran its first test program in 1949. This computer, manufactured by the government science organization (CSIRO), was used into the 1960s as a working machine at the University of Melbourne and still exists as a complete unit at the Museum of Victoria in Melbourne. Australia’s early entry into computing makes a comparison with the United States interesting. These early computers needed programmers, that is, people with the expertise to convert a problem into a mathematical representation directly executable by the computer. -

How to Effectively Listen and Enjoy a Classical Music Concert
HOW TO EFFECTIVELY LISTEN AND ENJOY A CLASSICAL MUSIC CONCERT 1. INTRODUCTION Hearing live music is one of the most pleasurable experiences available to human beings. The music sounds great, it feels great, and you get to watch the musicians as they create it. No matter what kind of music you love, try listening to it live. This guide focuses on classical music, a tradition that originated before recordings, radio, and the Internet, back when all music was live music. In those days live human beings performed for other live human beings, with everybody together in the same room. When heard in this way, classical music can have a special excitement. Hearing classical music in a concert can leave you feeling refreshed and energized. It can be fun. It can be romantic. It can be spiritual. It can also scare you to death. Classical music concerts can seem like snobby affairs full of foreign terminology and peculiar behavior. It can be hard to understand what’s going on. It can be hard to know how to act. Not to worry. Concerts are no weirder than any other pastime, and the rules of behavior are much simpler and easier to understand than, say, the stock market, football, or system software upgrades. If you haven’t been to a live concert before, or if you’ve been baffled by concerts, this guide will explain the rigmarole so you can relax and enjoy the music. 2. THE LISTENER'S JOB DESCRIPTION Classical music concerts can seem intimidating. It seems like you have to know a lot. -
