Retracted: Space Elements of Computer Music Production Based on VR Technology

Abstract

With the continuous development of computer technology and VR technology, computer music has become the mainstream music widely used in video, games and other major fields, and the research on computer music is becoming more and more important. At present, there are many research results about computer music software, but the research on space theory of computer music is slightly weak. In order to deeply study the space elements of computer music production, this paper takes Echo of the Wind as the research object and constructs the music space of virtual reality with VR technology. Firstly, the monitor system is calibrated, the virtual sound field is designed and adjusted, and reverberation and delay effectors are added to the sound field design template. After the VR music space is successfully constructed, the playback function of the server is tested. The audio in VR music space is extracted and processed. After the feature processing, the change of audio quality is counted. The results show that under the simulation of 150 users at the same time, the CPU consumption is 51%, the broadband consumption is 43.5%, and the good performance can still be maintained. After the audio feature processing, 91% of the audio can be converted to pitch normally, and 92% of the audio has no sound length deviation. The experimental results show that whether the traditional computer music or the computer music based on VR technology, the composition of the music space is mainly composed of timbre, voice part and depth space. INDEX TERMS VR Technology, Computer Music, Music Space Elements, Synthetic Timbre, MIDI Technology I. INTRODUCTION A. BACKGROUND SIGNIFICANCE Computer music has the advantages of various production methods, convenient storage and transmission, and high controllability, and has become an important part of new media information [1, 2]. The process of computer music production is also the composition process of music space. Only by studying and understanding the elements of music space, can we produce works with full space, clear levels and rich timbre [3]. VR technology can build a virtual space and put people in it. Through VR technology to help build music space, so that the illusory music space can be presented in front of everyone, which is more conducive to researchers' understanding of the elements of music space.

Transferring Music Pieces into Different Scales based on Nyquist Language

“…The root note of the music scale (Major or Minor) of a melody is estimated by fitting the notes to a music scale model. The estimated root note can then be used as the key in mode changing [12][13][14][15].…”

“…According to the analysis, one sees the future of computer music with different fields of studies, such as the ecology mentioned in Refs. [12][13][14][15]. The artefact ecology framework is also appealing.…”

A Study of Isan Folk Music Creation Using a Sampler for Music Education

“…Audio sampling technology has evolved over several decades, not limited to modern music but also encompassing the collection of sounds from various sources, including ethnic music, world music, orchestral, jazz, and music from all corners of the globe. It has become a valuable tool for music creators and producers, especially those with budget constraints, as it offers cost-effective alternatives to folk music production (Nopparat & Narkkong, 2019;Wang & Yu, 2020;Rambarran, 2021;Shang & Wang, 2022;Deruty et al, 2022).…”

Music Production Based on Brainwave and Acoustic Theory

“…After the processing of the acoustic function, 91% of the acoustic signals can be correctly converted to the basic frequency, and 92% of the acoustic signals have no obvious acoustic signals. The study found that, whether in traditional computer music or in virtual reality technology, its timbre, timbre and timbre are made up of three parts: timbre, timbre and depth [8]. This means that music produced virtually by modern computer software can have extremely high quality, and greatly provides convenience to musicians, which is also the premise of brainwave music generation.…”
