Edgetone

Edgetone is a term with limited and inconsistent use in specialized discourse. It may refer to a scientific concept, a brand name, or a project title, and there is no widely accepted definition.

In aeroacoustics and fluid dynamics, the closely related term edge tone describes a periodic tone produced when a jet of air impinges on or passes near a sharp edge. In informal or broad discussions some sources use "edgetone" as an alternative spelling or variant to refer to the same phenomenon or to a model of it.

In the field of music technology and audio production, "Edgetone" has been used as a brand name or product label by some independent developers for plug-ins, synthesizers, or hardware modules that emphasize edge-based tonal characteristics; due to the small scale of such projects, information is not centralized.

Etymology: The term combines "edge" and "tone," reflecting the edge-driven nature of the sound generation mechanism.
