Soundstack is free series of workshops, concerts and masterclasses focused on the art and technologies of spatial sound. It is an intermediate-level event, and requires some understanding of spatial sound. Its ethos is to make the tools for spatial technologies accessible, and thereby encourage plurality in the uptake of such tools. Soundstack brings together diverse publics, to introduce them to artist-engineers working at the cutting edge of spatial sound for VR, AR, installations and performance.
