In den Wald
interactive generative composition
2024-06-22

In den Wald is an immersive, interactive sound installation that blends technology with nature, inviting visitors to engage in a dynamic, evolving forest environment. Created for the Nature Unlimited exhibition at lange Nacht der Museen in the ArtPlus Museum in Donaueschingen, the installation uses a custom-built light barrier system to detect the number of people in the museum, generating a constantly shifting sonic landscape based on this data. 

The work explores the relationship between humans and nature, positioning visitors not just as observers but as active participants whose movements and presence influence the soundscape in real time.

The sound design of In den Wald is built around two layers: an atmospheric background and an interactive foreground. The background features forest-like sounds, rustling leaves, wind, and wood-like textures to create a tranquil, immersive environment in line with the exhibition's theme, "Nature Unlimited." The foreground evolves from percussive sounds to bird calls, which add a lively, organic element to the experience. The piece integrates four main sound groups: bird calls and synthesisers interacting with visitors, field recordings of forest sounds, and variable wind sounds that increase as more people enter the space.

At the heart of the installation is the custom-built light barrier system, which uses lasers and brightness sensors to track visitors’ movements. This system translates the data into MIDI messages, which are processed to drive generative sound elements. As people enter or exit the space, the system recalculates the sonic landscape, ensuring no two experiences are the same.

In den Wald offers a unique exploration of how technology can enhance the perception of natural environments, creating a living, breathing sound ecosystem where the boundary between human presence and nature blurs. The installation invites visitors to participate in the unfolding experience, fostering an evolving interaction between technology, sound, and nature.
