Klankclass

Klankclass is a term encountered in discussions of sound classification and timbre organization. It is a neologism that blends the Dutch word klank, meaning sound, with the English word class. In practice, it refers to a category of sounds defined by shared acoustic or perceptual properties. The term is not part of a single, widely adopted standard.

In linguistics, a klankclass may denote a group of phonemes or phones that share a feature set or a similar spectral profile. The label emphasizes auditory likeness—how the sounds are perceived—rather than formal articulatory features alone. Examples commonly discussed include a klankclass of voiceless stops or a klankclass of sibilant fricatives, though such groupings vary by author.

In computer music and sound design, klankclass can describe a collection of generators, samples, or resonators that produce related timbral qualities. Grouping modules into a klankclass can simplify control, with parameters adjusted to affect the entire class or to morph between members. This usage is common in modular synthesis and formant or modal synthesis contexts.

Because klankclass is not standardized, its definition is context dependent. Some authors treat it as a purely perceptual category; others tie it to specific acoustic measurements or to practical patching schemes in software and hardware environments.

The term remains niche and context-dependent, with no universal definition across linguistics or acoustics. Researchers typically specify their intended meaning when using the term.
