It was found that the production of sound by the kulintangan was dominated by a particular mode which may be the (0,1), (1,1), (2,2), (3,2), and (4,2) of free edge circular gong. The spectrum distribution from the strike on the kulintangan showed it. The small gong A-H has an approximately harmonic spectrum with a fundamental frequency of 1240, 1055, 934, 792, 705, 624, 474, and 422 Hz. The gong does not display a similar occurrence of harmonics due to the ruggedness of the surface texture of the gong. This finding can be of great importance to facilitate a better understanding of the mechanisms involved in the sound production of musical instruments. Our research is visualising the sound sonically through PicoScope oscilloscopes and ESPI.

Through the development of methods and technical possibilities, the study can contribute to high quality audio archiving that encompasses multiple sound perspectives. Thus it will help to preserve instrumental music in its sound context and document the unique relationship of the communities to it. The study is limited to a strict choice of instruments, which will play the role of a model for further applications. The study applies qualitative research methods, especially recording experiments leading to a descriptive analysis. From the fieldwork conducted, two selected local string instruments have been selected and recorded embedded in their actual sound context, namely the Bidayuh...

Gongs are a symbol of prosperity for the Bidayuh (Horsbourgh, 1858). Gong players gather and perform and are frequently joined by the traditional Bidayuh dance at an open space, 'awah' of the longhouse known as 'Kupuo'. There are three levels of tone attribute derivative from the gongs, namely 'canang', 'satu' and 'tawak'. In the community of Annah Rais, Padawan, Sarawak, there are tube zithers known as pratuokng, which contain a similar tone structure as the Bidayuh gong set and offer comparative collections. Seen from the point of view of sound preservation, the Audiovisual Research Collection for Performing Arts (ARCPA) located at the Music Department of Faculty of Human Ecology, UPM is stepping forward in developing elusive learning for a scholarly group to get to far-reaching database collections. In t...

Meanwhile, there is an increasing keenness in exploring the inception of reality in the Internet Era as the scholarly discussion on how IoT potentially changes the patterns of seeing, considering and representing the reality is in high demands at present. This paper proposes workable means of representable reality by generating and re-generating acoustic data that reflect spatial properties of a designated environment through technical formulation of reverberation simulation. It also considers possible conditions of such representation, especially the process control through real-time accessibility of data directly collected from machineāmachine communication via sensors, IP addresses and network connectivity. The methodological outcome of this simul...

The method of temporal localization on the dominant frequency at its unique time for each tone allows for the detection of frequencies present in the signal. Two approaches used in retrieving the harmonic, pitch, and timbre of kenong are Picoscope and Melda analyzer. The audio recording was done using an At4050 microphone and Ur22 audio interface in mono at 24-bit resolution and 48 kHz sampling rate. PicoScope produces the spectrum while the Melda analyzer produces changes in the spectra with time. Kenong D, E, G, A, and C displayed their near overtones at (2:2.8:4.0), (2:3.0:3.9), (2:2.9:3.9), (2:2.6:3.9), and (2:2.6:3.9). Kenong D had a strong fundamental peak at 295Hz. Kenong G keeps the fundamental frequenc...

A gambang is constructed from a wooden bar with a similar thickness and width but a different length. The sound and established frequencies were compared with the equal tempered scale. The peak differed from the intended pitch and the partials were not always harmonic. This gambang only classified 4 octaves. The audio classification of the gambang was based on signal processing using a Picoscope oscilloscope. This article explains how wood is transformed into musical instruments. The findings revealed that the sound aspect and sound value of the wood keyboard instruments differed from the desired pitch. The third octave notes created C5, E5, E5, G5, and A5 instead of C5, D5, E5, G5, and A5, while the fourth octave pitch produced C6, D6, E6, G6, and A6# instead of C6, D6, E6, G6, and A6. Only the third and fourth octaves exhibited nearly flawless tuning for the gambang.

Eurostring1 and Eurostring2 were the names given to the two Eurostring units. The purpose of this study is to identify elements in various violins that could be used as tools for selecting a pleasantsounding violin by having them classified by a professional violinist. The signalās time varying frequency was evaluated using a frequency spectrum and a time frequency plane, and the combination of frequency spectrum and time frequency domain is utilised. PicoScope oscilloscopes and Adobe Audition version 3 were used to record the acoustic spectra in terms of time and frequency. The time frequency plane is identified, and time frequency analysis (TFA) is produced by Adobe Audition spectrograms. The sound was processed in order to generate Fast Fourier Transform analysis: Fourier spectra (using PicoScope) and spectrograms (using Adobe Audition). Fourie...

Recordings of ethnic instruments that are available in the marketplace today show various types of timbre determined by different sampling rates, choice of microphone placements and acoustic environment. In many cases, the timbre produced in recordings of one ethnic instrument called sape is highly diversified. Music recordings available for ethnic instruments such as the sape of the Orang Ulu, Kenyah and other ethnic groups were manipulated either through the sound of the instrument itself or through the original recording that was extracted from various recording mediums, or recorded in a āmock-upā context created by producers. The effects of all these manipulations have misled listeners into thinking that what they are hearing are the original sounds of instruments such a...

They need data derived from professional recordings that help to support conventional observations. Media distributors have long-held the role of environment sounds as disturbing nuisance that had to be eliminated or suppressed. In the best / worst case, side sounds were left unchanged to create a "lively" atmosphere for an anthropological sound recording or a sound recording for a special audience to which the place of the performance is of particular interest. The coughing in a live concert or the dog barking in the background of a village ensemble became then part of the marketed item. In an archive, sound reductions hopefully not take place. Nevertheless, environmental sound inclusions, in certain recordings, are considered to be side effects of the main recording project undertaken by collectors of different disciplines who did not purposely intended to...

It is also known as a simple idiochord chordophone. It is made of a petung bamboo, and the sound faculty is equivalent to the functions of the Bidayuh community gong set. The sound radiator meaning is made up of tawak, satuk and canang. A similar tube zither made of bamboo, named pretong or sretong, is used by the Bidayuh of Bau. The three-string sound radiators are kromong, canang, gong, plus the tawak and gedabak. Pratuokng sound radiators are like the gongs of the Bidayuh. According to Horsbourgh's observation, "... gongs... are both a musical instrument and a representation of wealthā2. The Annah Rais Bidayuh gong set, privately owned by the villagers, can be typically played every year for ritual practice as well as for entertainment during the Gawai celebration on the first and second June. The audio collection of the Ethnology Section of the Sarawak Museum provides similar recordings from ot...

It seems to be difficult for them to do current multitrack recordings and at the same time maintaining the aesthetic aspect of past technology. In other words, if one preserves the recorded item, they have also to care about the specific features coming with these recordings. It is not the primary recorded subject alone they may have to consider. There is an urgency to migrate the recorded material such as cassette tapes that come in varying forms ranging from Ferric-Oxide, to Cro2, and Metal. These carriers are warranted to be extracted and migrate onto a more stable medium, not only in general as everywhere in the world, but also since it has become the university policy that equipmentās exceeding certain years will be disposed of.

The fast Fourier transform (FFT) of sompoton was determined via a Pico oscilloscope. All three sompotons displayed almost similar fundamental frequencies. The individual tubes 1, 2, 3, 4, 5, 6, and 8 (except tube 7) of sompoton I, II, and III produced the fundamental frequency (in hertz) as 924, 758, 655, 589, 449, 407, 537, as 954, 779, 655, 614, 469, 387, 552, and as 944, 820, 655, 635, 407, 407, and 552, respectively. The averaged frequency obtained from the three sompotons (with the diatonic frequency and note in bracket) was 940.6 (932.3-A5# tube 1), 785.6 (783.9-G5 tube 2), 655 (659.2-E5 tube 3), 612.6 (622.2-D5# tube 4), 547 (554.3-C5# tube 8), 441.6 (440-A4 tube 5), and 400.3 (392-G4 tube 6). The tunings were remarkably similar in the tonal relationships. The pitch of the drone tube (tube 6) repeated an octave higher at tube 2, the intervals of perfect 4th higher at tube 8, and the intervals of ...
