Extended Waveform Segment Synthesis, a Nonstandard Synthesis Model for Microsound Composition

This paper discusses a non-standard technique for timedomain waveform synthesis. In Extended Waveform Segment Synthesis sound is described as a structure of blocks of amplitude micro-fluctuations. These structures can be updated during synthesis or different structures can be combined generating dynamic evolving waveforms. This technique is intended to be: first, an extension of the existing linear segment synthesis techniques, second a generalized framework of various existing non-standard techniques like stochastic waveform synthesis or pulsar synthesis and third, the basis of new directions in composing the sound and in waveform transformation. The concept of a compositional structure that goes down to the microlevel is also presented.
