Bmód

Bmód is a specialised term within digital audio engineering that refers to a modular synthesis system designed for real‑time manipulation of sound waveforms based on biological modulation patterns. The concept was first introduced in 2014 by a research group at the University of Freiburg, who sought to incorporate naturally occurring signal variations into modular synthesizers. The Bmód architecture consists of a series of independent modules, each capable of being patched together via a standardized Eurorack format. Unlike conventional modular systems, Bmód modules are equipped with adaptive algorithms that analyse input signals and generate modulation cues derived from physiological data such as heart‑rate variability or electrodermal activity. This approach enables performers to use bodily states as expressive control parameters, creating a direct link between physiological responses and sonic output.

In practice, Bmód is employed both in live performance and studio settings. Artists often pair the system with traditional virtual instruments, using Bmód’s modulation outputs to drive LFOs, filter envelopes, and pitch shifts. The research community has tested the platform in studies of multisensory integration, reporting increased engagement when users perform with Bmód‑controlled instruments. Production software manufacturers have begun to incorporate Bmód SDKs into plug‑in offerings, allowing developers to embed biometric modulation into commercial audio products. While Bmód remains a niche tool, its interdisciplinary focus highlights emerging trends in bio‑mediated music creation and the broader movement toward more embodied interaction with technology.
