    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.

  • What Is a Magnetic Tape Recorders
    What is a Magnetic Tape Recorders Before explaining about magnetic tape recorders, I will tell you what a recorder is and what the uses of the recorder are? A recorder is used to produce a permanent record of the signal that is measured. A record is used to analyse how one variable varies with respect to another and how the signal saries with time. The objective of a recording system is to record and preserve information pertaining to measurement at a particular time and also to get an idea of the performance of the unit and to provide the results of the steps taken by the operator. The basic components of a general recorder are an operating mechanism to position the pen or writer on the paper and a paper mechanism for paper movement and a printing mechanism. Okay, now you know what is a recorder, why it is used and where it is used. Now I will explain about magnetic tape recorder. A magnetic tape recorder is used to record data which can be retrieved and reproduced in electrical form again. This recorder can record signals of high frequency. Description of Magnetic Tape Recorders: The magnetic tape is made of a thin sheet of tough plastic material; one side of it is coated with a magnetic material (iron oxide). The plastic base is usually polyvinyl chloride (PVC) or polyethylene terephthalate. Recording head, reproducing head and tape transport mechanism are also present. Operation of Magnetic Tape Recorders: 1. The recording head consists of core, coil and a fine air gap of about 10 micrometer.

  • Historical Development of Magnetic Recording and Tape Recorder 3 Masanori Kimizuka
    Historical Development of Magnetic Recording and Tape Recorder 3 Masanori Kimizuka ■ Abstract The history of sound recording started with the "Phonograph," the machine invented by Thomas Edison in the USA in 1877. Following that invention, Oberlin Smith, an American engineer, announced his idea for magnetic recording in 1888. Ten years later, Valdemar Poulsen, a Danish telephone engineer, invented the world's frst magnetic recorder, called the "Telegraphone," in 1898. The Telegraphone used thin metal wire as the recording material. Though wire recorders like the Telegraphone did not become popular, research on magnetic recording continued all over the world, and a new type of recorder that used tape coated with magnetic powder instead of metal wire as the recording material was invented in the 1920's. The real archetype of the modern tape recorder, the "Magnetophone," which was developed in Germany in the mid-1930's, was based on this recorder.After World War II, the USA conducted extensive research on the technology of the requisitioned Magnetophone and subsequently developed a modern professional tape recorder. Since the functionality of this tape recorder was superior to that of the conventional disc recorder, several broadcast stations immediately introduced new machines to their radio broadcasting operations. The tape recorder was soon introduced to the consumer market also, which led to a very rapid increase in the number of machines produced. In Japan, Tokyo Tsushin Kogyo, which eventually changed its name to Sony, started investigating magnetic recording technology after the end of the war and soon developed their original magnetic tape and recorder. In 1950 they released the frst Japanese tape recorder.

  • Digital Audio Tapes: Their Preservation and Conversion 1 Smithsonian Institution Archives Summer 2010
    Digital Audio Tapes: Their Preservation and Conversion 1 Smithsonian Institution Archives Summer 2010 Digital Audio Tapes: Their Preservation and Conversion Susan Eldridge, Digital Services Intern Overview Digital Audio Tapes (DATs) are 4mm (or 3.81mm) magnetic tape cassettes that store audio information in a digital manner. DATS are visually similar to compact audio cassettes, though approximately half the size, use thinner tapes, and can only be recorded on one side. Developed by Sony in 1987, DATs were quite popular in recording studios and were one of the first digital recording systems to become employed in archives in the late 1980s and 1990s due to their lossless encoding. Commercial use of DATs, on the other hand, never achieved the same success as the machines were expensive and commercial recordings were not available on DAT. Depending on the tape and machine used, DATs allow four different sampling modes: 32 kHz at 12 bits quantization, and 32 kHz, 44.1 kHz, and 48 kHz at 16 bits.1 All support two-channel stereo recording. Some of the later DATs (before being discontinued) could extend the bit-depth to 24 and up to 98 kHz, however, these tapes were likely rarely playable on other models.2 DATs can run between 15 and 180 minutes in length, one again depending on the tape and quality of the sampling. Unlike some other digital media, DATs do not use lossy data compression, which is important in the lossless transferring of a digital source to a DAT. Sony ultimately discontinued the production of DAT machines in 2005.3 Composition A digital magnetic tape is composed of two primary layers: the base film and magnetic layer.
