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. Tools for Digital Audio Recording in Qualitative Research Alan Stockdale In a recent book Michael Patton writes, “As a naïveté, can heighten the sense of “being Dr. Stockdaleʼs training is in good hammer is essential to fine carpentry, there”. For discussion of the naturalization cultural anthropology.

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. -

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.
