The Luka‐chucK is a glitch audio composition environment that uses the ChucK programming language as its audio engine. It can be used to generate audio fragments or entire works. A user interface is provided using communication to Max/MSP via open sound control. A key motivation for this project is the development of features that allow the user to anticipate and control sonic results that emerge from digital audio glitches, and to increase the compatibility of such sounds with other materials used to compose electroacoustic music. With the interface, users can input data to modify pitch, rhythmic, timbral and textural elements by affecting algorithmic devices such as looping and conditional statements. The glitch sounds can also be modified by conventional tools such as a step sequencer, musical keyboard and the use of low frequency oscillators. The environment includes a number of audio instruments based on techniques such as foldover from aliasing, the use of infrasonic frequency content, and quality factor glitches with resonant filters. The purpose of this paper is to discuss motivations, applications and further work related to the development of the Luka‐chucK project.
