Tools for Digital Audio Recording in Qualitative Research
Sociology at Surrey University of Surrey social researchUPDATE • The technology needed to make digital recordings of interviews and meetings for the purpose of qualitative research is described. • The advantages of using digital audio technology are outlined. • The technical background needed to make an informed choice of technology is summarised. • The Update concludes with brief evaluations of the types of audio recorder currently available.

How to Tape-Record Primate Vocalisations Version June 2001
How To Tape-Record Primate Vocalisations Version June 2001 Thomas Geissmann Institute of Zoology, Tierärztliche Hochschule Hannover, D-30559 Hannover, Germany E-mail: [email protected] Key Words: Sound, vocalisation, song, call, tape-recorder, microphone Clarence R. Carpenter at Doi Dao (north of Chiengmai, Thailand) in 1937, with the parabolic reflector which was used for making the first sound- recordings of wild gibbons (from Carpenter, 1940, p. 26). Introduction Ornithologists have been exploring the possibilities and the methodology of tape- recording and archiving animal sounds for many decades. Primatologists, however, have only recently become aware that tape-recordings of primate sound may be just as valuable as traditional scientific specimens such as skins or skeletons, and should be preserved for posterity. Audio recordings should be fully documented, archived and curated to ensure proper care and accessibility. As natural populations disappear, sound archives will become increasingly important. This is an introductory text on how to tape-record primate vocalisations. It provides some information on the advantages and disadvantages of various types of equipment, and gives some tips for better recordings of primate vocalizations, both in the field and in the zoo. Ornithologists studying bird sound have to deal with very similar problems, and their introductory texts are recommended for further study (e.g. Budney & Grotke 1997; © Thomas Geissmann Geissmann: How to Tape-Record Primate Vocalisations 2 Kroodsman et al. 1996). For further information see also the websites listed at the end of this article. As a rule, prices for sound equipment go up over the years. Prices for equipment discussed below are in US$ and should only be used as very rough estimates. -

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. -
Application Notes
Measurement of Loudspeaker and Microphone Performance using Dual Channel FFT-Analysis by Henrik Biering M.Sc, Briiel&Kjcer Introduction In general, the components of an audio system have well-defined — mostly electrical — inputs and out puts. This is a great advantage when it comes to objective measurements of the performance of such devices. Loudspeakers and microphones, how ever, being electro-acoustic transduc ers, are the major exceptions to the rule and present us with two impor tant problems to be considered before meaningful evaluation of these devices is possible. Firstly, since measuring instru ments are based on the processing of electrical signals, any measurement of acoustical performance involves the Fig. 1. General set-up for loudspeaker measurements.

Secondly, neither the output of a loudspeaker nor the input to a micro phone are well-defined under practical circumstances where the interaction between the transducer and the room cannot be neglected if meaningful re sults — i.e. results correlating with subjective evaluations — are to be ob tained.

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. -

An interface for manipulating these elements is suggested, based on the concept of a disk-jockey turntable as a performance instrument. A system is developed around this idea, enabling optical pickup of visual informa- tion from physical media as input to processes on the computer. Software architecture(s) are discussed and examples are implemented, illustrating the potential uses of the interface for the purpose of creative expression in the virtual domain.
