waveroom

One of Karel's recordings, played back as a point source inside a simulated resonant chamber. A real acoustic wave equation propagates its pressure across the room — wavefronts expand, reflect off the walls, and interfere into standing-wave patterns. Move the listener through the field and you hear the room from where you stand: antinodes are loud and open, nodes fall to a whisper.

This is not a mixer. There is one source. Walking the room is hearing its acoustic modes.
