This paper presents software development and research on the field of digital audio synthesis of spectral data using the Pure Data environment (Miller Puckette et al) and the ATS spectral analysis technique (by Juan Pampin [6]). The ATS technique produces spectral data using a deterministic-plus-stochastic representation. The focus is on the methods by which such data may be real-time read and synthesized using several Pure Data externals developed by the author and others, as well as on the involved audio synthesis strategies. All the software involved in this development is GNU Licensed and runs under Linux.

The Pitch-class set theory and its extensions constitute an important basis for mastering multi- layered atonal composition. The SuperCollider environment offers significant possibilities of applying this technique in the creation of abstract Pitch-class designs that may be used as a part of more complex algorithmic composition developments. This paper presents pcslib-sc a quark (library) for Pitch-class set design in SuperCollider and an use case in order to demonstrate its musical relevance.
