Digital Music Waveform Analysis and Retrieval Based on Feature Extraction Algorithm

In order to improve the feature extraction effect of digital music and improve the efficiency of music retrieval, this paper combines digital technology to analyze music waveforms, extract music features, and realize digital processing of music features. Taking the extraction of waveform music file features as the starting point, this paper combines the digital music feature extraction algorithm to build a music feature extraction model and conducts an in-depth analysis of the digital music waveform extraction process. In addition, by setting the threshold, the linear difference between the sampling points on both sides of the threshold on the leading edge of the waveform is used to obtain the overthreshold time. From the experimental research results, it can be seen that the music feature extraction model based on digital music waveform analysis proposed in this paper has good results.

instance: Soma-based multi-user interaction design for the telematic sonic arts

The telematic work instance is a performance for viola and dance that digitally connects performers in Vancouver and Cape Town. The network interface enables a violist and a dancer to simultaneously play multi-user digital music-dance instruments over the internet with music and dance. The composition, design and performance interaction of instance draw from acoustic multi-user instrument paradigms and music-dance interactions in the African performing arts to explore the idiosyncrasies of the telematic performance space. The iterative design process implements soma-based research methods to inspire sonic compositional material with the body and to explore the performers’ embodied experience of sonic aesthetics during their interaction.

Türkiye’de Dijital Müzikteki Yeni Ekonomik Modellerin Sosyolojik ve Kültürel Yönleri

This research explained new economic models in the digital music industry in view of cultural, technological, and sociological aspects. The importance of local entrepreneurship, as well as global markets, were accessed. There have been many developments in digital music in the past two decades. These developments have affected relations between the digital economy and music technology. The study is mainly focused on the Turkish music market. Why the subscription and bundling models are on the rise? How does an economic merger between telecommunication companies and digital music services work? What are the effects of the recent developments in technology, in particular smartphones on music industry? The partnership of Turkcell, the largest GSM operator in Turkey, and one of the top 5 in Europe and Turkish digital music service Fizy was exemplified. Thus, the significance of local markets in the digital era, expectations of the audiences, the applicability of streaming, and bundling economic models in Turkey have been examined.
