Frequency Classes

coupled-oscillators#

Phase oscillators on a graph, integrated forward under a coupling constant. Coherence drifts between ordered and disordered; the order parameter is the natural control signal for register and voice count. Slow, drone-shaped output.

cellular-automaton#

A discrete lattice under a fixed local rule. Fully specified by the rule number and the initial row. Percussive and rhythmic output; structure appears without being composed.

granular-synthesis#

A grain cloud evolving under a stochastic field. Density function, pitch-shift range and grain envelope are the design choices; the source corpus and its licence are the sourced data. Textural output. Citation: Roads, Microsound (ISBN 978-0-262-18215-7). This class alone requires sample clearance at launch: if the grain corpus contains copyrighted recordings, its licence status must be stated and the file hashed on chain.

physical-modeling-resonator#

A network of coupled resonators, each with its own excitation and decay, exchanging energy with its neighbours under damping. Struck nodes are sounded by plucked-string synthesis. Citation: Karplus and Strong, “Digital Synthesis of Plucked-String and Drum Timbres” (10.2307/3680062).

stochastic-process#

A formalized process stepped once per tick with entropy drawn from the block hash. The named distribution; Markov chain over scale degrees, Ornstein-Uhlenbeck field, Poisson point process, or sieve theory; is declared in the specification and recorded as sourced data, along with its parameters. Markov chains are one technique inside this class, not a class of their own.
