  Corpus-Based Sound Modelling for Computer-aided Composition.   Overview OM-Pursuit is a library for dictionary-based sound analysis/synthesis methods in OpenMusic. Parametric sound representations have since long served as conceptual models in composition contexts (see e.g. the French spectralist school). Today there are a number of software tools allowing composers to derive symbolic data from continuous sound phenomena, such […]


What is the Word

What is the word   … was created in 2008 during my program in music theory/computer music as a study for purely deterministic, rule-based algorithmic composition. Driven by a fascination of dialectic processes, this acousmatic work is characterized by an extreme reduction of sound materials, being composed exclusively from synthesized pure tones and algorithmically-transformed speech […]



Spatial Sound Synthesis Framework for Computer-aided Composition.   Overview OMPrisma is a library for spatial sound synthesis in the computer-aided composition environment OpenMusic. In addition to working with pre-existing sound sources (i.e. sound files) it permits the synthesis of sounds with complex spatial morphologies controlled by processes developed in OpenMusic in relation to other sound […]

Introduction to the CIRMMT Live Electronics Framework

Today we reviewed some of the most popular signal processing techniques used in live-electronics music repertoire. These included: delays (tap/feedback delays) flanger, chorus, phaser reverberation filtering (IIR/FIR also sometimes referred to as resonant vs fft) modulation (AM, FM, Ringmodulation) pitch shifting and harmonization Convolution, Cross-synthesis phase vocoding (time-stretching and freezing of sounds) We also listened […]



  Symbolic Audio Manipulation and Functional Batch Processing. OM-SoX is a free, cross-platform (Windows, MacOS, Linux), open source library for symbolic audio manipulation, analysis and batch processing, integrated in the computer-aided composition (CAC) environment OpenMusic. OM-SoX implements a structured framework of classes and functions comprising > 50 audio processors. Using visual programming tools, dsp-topologies can be constructed and related to […]
