We will be examining sound visualisation software, and its evolution over the thirty-five year timespan in which it has existed. How we judge software, is based on aesthetic criteria, the way they were handed down to us from theories of abstract painting (20th century avant-garde) , the theory of montage by Sergei Eisenstein, of neurophysiology (synesthesia, muscular images) and of the successful correspondence of the two media (pixel and music) in the works and theory of James Whitney.

In the domain of Ancient Greek musicology indeed, where we find the roots of the occidental music, the main research has been done mostly by scholars of classical Greek literature. However, there is still a vast territory for research in audio performances to be carried out with the help of new digital technologies.

Recent work shows that the musical and natural quality of singing voice synthesis has evolved enough for high fidelity commercial applications to be realistically envisioned.

Background in composition This paper refers also, to a particular point of view in composition using e/a material in order to achieve this sound structure that conventional means could not create. This is an advantage of the e/a sound editing, based on the flexibility of handling the sound as a plastic material. This technical topic brings new aesthetic and structural questions so at the conception of a work as at its realization too. A critical confrontation of editing ready given samples to newly made. Aims Distinguishing the recorded playback music from the e/a material we realize the s...

In this article we present a brief overview of the genesis and evolution of the electroacoustic music in Greece since 1967 until today, exposing three crucial periods. In the second section we present the works, the means and aesthetics of representative composers of the most recent period (1990-2005). In the last section we focus on the pedagogical and institutional development of the Greek electroacoustic music during the last fifteen years, as well as on the diversity of styles and techniques of works presented in various events in Athens and other places in Greece. We also stress the lack of an official institute for the archiving, creation and expansion of the electroacoustic music, and the indifference of the cultural authorities to cultivate such kind of music.

Building on previous research, we employ a hybrid musical instrument: Phonodeon (Georgaki et al. 2005), consisting of a MIDI-accordeon coupled to a real-time algorithmic interaction and vocal synthesis engine. The synthesis is based on data provided by the AOIDOS program developed in the Department of the Computer science of the University of Athens, investigating Greek liturgical chant compared to bel canto singing. Phonodeon controls expressive vocal synthesis models based on formant synthesis and concatenated filtered samples. Its bellows serve as hardware control device that is physically analogous to the human breathing mechanism [georgaki, 1998a], while the buttons of the right hand can serve multiple functions. On the level of pitch structure, this paper focuses on a particular aspect of control, namely that of playing in the traditional non-tempered and flexible inte...

Our goal is to implement a score-to-singing synthesis system, where the score is written in a score editor and saved in the midi format. However, MBROLA accepts phonetic files as input rather than midi ones and because of this, we construct a midi-file to phonetic-file converter, which applies irrespective of the underlying language. The evaluation of the Greek singing voice synthesis system is achieved through a psycho acoustic experiment. The thirty participants are given two samples and are asked to evaluate them according to vocalness, naturalness, intelligibility and expressivity, in a 1-5 scale MOS test. The results are encouraging, with naturalness and expressivity being ranked above 2.5 in average. Thereafter, we create a new diphone database, from the same text corpus but with a different human voice. The text is rec...

After much valuable work has been done to carefully collect, philologically ensure and cautiously construe the manifold relations of music related texts [Barker 1984/1989, West 1992] scholars have begun to review the scarce evidence of musical fragments [Pöhlmann & West 2001] in order to trace historical changes with-in the development of Ancient Greek music. Research mainly concentrated on scales and tuning [Franklin 2005], the role of modulation [Hagel 2000] and the intersection with philosophy — which, from the outset, keenly explored the rich 'Episteme of music 1 encompassing a wide field of knowledge that Barker outlines as "harmonic science" [Barker 2007]. However, the agency of musical notation (parasémantiké techné) as a medium and the charac...

On the one hand, we will refer to the main domains of Xenakis' contributions to Music Technology: the conquest of the computer as a tool for logical transformations of symbols into music and a laboratory of automation for certain compositional tasks on meta-musical and compositional design issues; his pedagogical and compositional approach by the sound-design system UPIC as an interface between musician and machine; his granular approaches of sound synthesis as a link between algorithms and the creation of new sounds; the multi-sensoring approach of the conception of Polytopes where he combines various technological tools in order to achieve a kind of a total art work. On the other hand, we will exalt the impact of his research in current music technology (use of the granular model in mo...

Our scope is to facilitate the access of visually impaired persons to musical databases (scores, audio and MIDI files) via Internet and give them the possibility to edit and create musical scores.

It is divided into two parts. The first part of the study is based upon reference, investigating the interconnection between art and science. This mechanism is characterized by transformation processes in the interdisciplinary practices that are applied mainly by various artists and movements of the post-Second World War period. The ...
