These Founding Documents mark the beginning of Acoustic Architecture, an evolving practice exploring how sound, space, memory, and attention can be composed into deeply human experiences. Created for the High End Society Show in Vienna, Austria, from June 4–7, 2026, this edition serves as both an introduction and an invitation: a first physical artifact outlining the ideas behind the project, the Berlin listening sessions that initiated its development, and the larger ambition to build environments where music is not simply played, but inhabited. Handed individually, these documents are intended less as promotional material and more as an archival gesture — a small piece of the project’s foundation, offered to future collaborators, supporters, researchers, artists, designers, and audio partners who may help shape what Acoustic Architecture becomes.
