This paper presents rhythm reading, one of the elementary ear training exercises, as a pedagogical software application of PWGL. We use different kinds of stochastic and mathematical models to generate a rhythmic database. The database is divided into several categories, including, binary or ternary, euclidian, afro-cuban, corpus-based, and contemporary. Our musical constraints systems is used to define a rule set, which, in turn, can be used to automatically generate graded rhythm reading exercises. The user is then presented with a musical score, and he or she can perform a reading with any percussive instrument or voice and a microphone connected to a computer. Our novel signal processing system is utilized to analyze the reading. Finally, visual feedback and statistics are displayed directly as a part of the exercise. In this paper we present our rhythm reading application, and discuss the details of its implementation. © 2013 Springer-Verlag. Source

Kronos is a visual-oriented programming language and a compiler aimed at musical signal processing tasks. Its distinctive feature is the support for functional programming idioms like closures and higher order functions in the context of high performance real time DSP. This paper examines the visual aspect of the system. The programming user interface is discussed, along with a scheme for building custom data visualization algorithms inside the system. Source

An application of ecological psychology, based on the work of James J. Gibson, to electroacoustic music would consider the listener in relationship with both the work and the environment, in a dynamic and mutually informing relationship. This perspective is applied to various electroacoustic concert paradigms, demonstrating a wide range of listening experiences; the implications for electroacoustic music as a genre are examined. Several qualities of acousmatic music are used to explore some potential limitations of Gibson's theories. Finally, some relative strengths and weaknesses of ecological psychology are considered, as well as some potentially fruitful cooperations with other, somewhat divergent, theoretical approaches. © 2011 Cambridge University Press.

This paper presents the latest developments of the SUM tool, aimed at the integration of image and sound. A user library within the PWGL visual programming environment, it allows both image sonification and graphical computer-aided composition. Initially developed for the sonification of graphic urban maps, in which MIDI data is generated from graphics, the SUM process can now be reversed, with MIDI being the generator of the graphics themselves. We present three new developments which allow this: the ability to import MIDI into SUM to generate spatio-temporal vector time-paths; the ability to access the temporal structure of these paths through its points; and the ability to draw vector objects and develop a custommade object library. These functions will allow us to generate graphics from music, which may form the basis of future works of 'visual music' as well as the musicalgeneration of graphical designs. Source

This paper presents a formal grammar for discussing data flows and dependencies in audio processing graphs. A graph is a highly general representation of an algorithm, applicable to most DSP processes. To demonstrate and exercise the grammar, three central problems in audio graph processing are examined. The grammar is used to exhaustively analyze the problem of scheduling processing nodes of the graph, examine automatic parallelization as well as signal rate inferral. The grammar is presented in terms of mathematical set theory, independent of and thus applicable to any conceivable software platform. Source
