Keynote Talk 3 The ATS technique in Csound: theoretical background, present state and prospective Oscar Pablo Di Liscia Universidad Nacional de Quilmes, Argentina Abstract The ATS technique (Analysis.Transformation-Synthesis) was developed by the composer and researcher <uan (ampin (CRA)TS &7 &SA). 4ssentially it represents two aspects of the analyzed signalM the deterministic part and the stochastic part. This model was initially conceived by <ulius 1rion Smith and Ravier Serra, but ATS refines certain aspects of it such as the inclusion of psycho-acoustic data. The deterministic part consists of sinusoidal traDectories with varying amplitude, frequency and phase. It is obtained performing high-level analysis on the spectral data obtained using Short. Time /ourier Transform analysis. The stochastic part is also termed residual because it is achieved by subtracting the deterministic signal from the original signal. Since approximately "##$ several applications were developed by a team of academics from &AS (Argentina) and &7 Seattle (&SA). These applications included stand alone programs as well as unit generators for environments li-e (ure Data, SuperCollider and Csound.

  • Interactive Csound Coding with Emacs
    Interactive Csound coding with Emacs Hlöðver Sigurðsson Abstract. This paper will cover the features of the Emacs package csound-mode, a new major-mode for Csound coding. The package is in most part a typical emacs major mode where indentation rules, comple- tions, docstrings and syntax highlighting are provided. With an extra feature of a REPL1, that is based on running csound instance through the csound-api. Similar to csound-repl.vim[1] csound- mode strives to enable the Csound user a faster feedback loop by offering a REPL instance inside of the text editor. Making the gap between de- velopment and the final output reachable within a real-time interaction. 1 Introduction After reading the changelog of Emacs 25.1[2] I discovered a new Emacs feature of dynamic modules, enabling the possibility of Foreign Function Interface(FFI). Being insired by Gogins’s recent Common Lisp FFI for the CsoundAPI[3], I decided to use this new feature and develop an FFI for Csound. I made the dynamic module which ports the greater part of the C-lang’s csound-api and wrote some of Steven Yi’s csound-api examples for Elisp, which can be found on the Gihub page for CsoundAPI-emacsLisp[4]. This sparked my idea of creating a new REPL based Csound major mode for Emacs. As a composer using Csound, I feel the need to be close to that which I’m composing at any given moment. From previous Csound front-end tools I’ve used, the time between writing a Csound statement and hearing its output has been for me a too long process of mouseclicking and/or changing windows.

  • Expanding the Power of Csound with Integrated Html and Javascript
    Michael Gogins. Expanding the Power of Csound with Intergrated HTML and JavaScript EXPANDING THE POWER OF CSOUND WITH INTEGRATED HTML AND JAVA SCRIPT Michael Gogins [email protected] https://michaelgogins.tumblr.com http://michaelgogins.tumblr.com/ This paper presents recent developments integrating Csound [1] with HTML [2] and JavaScript [3, 4]. For those new to Csound, it is a “MUSIC N” style, user- programmable software sound synthesizer, one of the first yet still being extended, written mostly in the C language. No synthesizer is more powerful. Csound can now run in an interactive Web page, using all the capabilities of current Web browsers: custom widgets, 2- and 3-dimensional animated and interactive graphics canvases, video, data storage, WebSockets, Web Audio, mathematics typesetting, etc. See the whole list at HTML5 TEST [5]. Above all, the JavaScript programming language can be used to control Csound, extend its capabilities, generate scores, and more. JavaScript is the “glue” that binds together the components and capabilities of HTML5. JavaScript is a full-featured, dynamically typed language that supports functional programming and prototype-based object- oriented programming. In most browsers, the JavaScript virtual machine includes a just- in-time compiler that runs about 4 times slower than compiled C, very fast for a dynamic language. JavaScript has limitations. It is single-threaded, and in standard browsers, is not permitted to access the local file system outside the browser's sandbox. But most musical applications can use an embedded browser, which bypasses the sandbox and accesses the local file system. HTML Environments for Csound There are two approaches to integrating Csound with HTML and JavaScript.

  • Algorithmic Composition with Open Music and Csound: Two Examples
    Algorithmic Composition with Open Music and Csound: two examples Fabio De Sanctis De Benedictis ISSM \P. Mascagni" { Leghorn (Italy) [email protected] Abstract. In this paper, after a concise and not exhaustive review about GUI software related to Csound, and brief notes about Algorithmic Com- position, two examples of Open Music patches will be illustrated, taken from the pre-compositive work in some author's compositions. These patches are utilized for sound generation and spatialization using Csound as synthesis engine. Very specific and thorough Csound programming ex- amples will be not discussed here, even if automatically generated .csd file examples will be showed, nor will it be possible to explain in detail Open Music patches; however we retain that what will be described can stimulate the reader towards further deepening. Keywords: Csound, Algorithmic Composition, Open Music, Electronic Music, Sound Spatialization, Music Composition 1 Introduction As well-known, \Csound is a sound and music computing system"([1], p. 35), founded on a text file containing synthesis instructions and the score, that the software reads and transforms into sound. By its very nature Csound can be supported by other software that facilitates the writing of code, or that, provided by a graphic interface, can use Csound itself as synthesis engine. Dave Phillips has mentioned several in his book ([2]): hYdraJ by Malte Steiner; Cecilia by Jean Piche and Alexander Burton; Silence by Michael Go- gins; the family of HPK software, by Didiel Debril and Jean-Pierre Lemoine.1 The book by Bianchini and Cipriani encloses Windows software for interfacing Csound, and various utilities ([6]).

Karpen James Coupe Program Authorized to Offer Degree: Digital Arts and Experimental Media University of Washington Abstract Axial; a Sound Art Work of an Oceanographic Expedition Hugo Solis Chair of the Supervisory Committee: Dr. Juan Pampin DXARTS Axial is a sound installation in which a cargo container is employed as a resonant object: resonant in its acoustic sense because the container is used as sound generator, but also resonant in its metaphorical connotation because the container and the generated sounds translate and represent the geological properties of Axial, an active submarine volcano on the Juan de Fuca Ridge located about 250 miles off the coast of Oregon. The container is also the space-instrument for interpreting the scientific data obtained during the oceanographic expedition Enlighten10, during which the artist recorded the sounds of the hydrothermal vents located in the area at depth of over 4,500 feet. This thesis describes in detail the entire compositional process as well as the con- cepts, procedures, and context of the artwork. Chapter one offers a general description of the project and should be the starting point for a first-time reader because it helps to establish the context. Chapter two describes the concept of digital plurifocality and presents the properties of the Plurifocal Events Controller, a technological infrastructure for creating spatially distributed sound works.

  • Building a Synthesizer Using Csound and the Intel Galileo: Towards an Internet of Things Music Programming Environment
    Building a synthesizer using Csound and the Intel Galileo: towards an Internet of Things music programming environment Lazzarini Victor1,Timoney Joe1, Byrne Shane1 1 Maynooth University, Maynooth, Co. Kildare, Ireland [email protected] Summary This paper explains how the Intel Galileo can be configured to run as a music synthesizer. A special build of the music programming language application Csound was configured to run on the Intel Galileo. Achieving this meant that the Galileo could be set up to receive Midi information over USB that could drive a music synthesizer system. Furthermore, sound parameters could be controlled using Midi to allow real-time timbral change. The next step is to integrate this in as an Internet of Things (IoT) music application, providing a new technology platform to allow musicians to program, compose and play music from disparate locations. 1. Introduction Arduino to run and control Csound.
