Welcome to the Spatialization and Auditory Display Environment
The Spatialization and Auditory Display Environment (SpADE) is a specialised 32-channel surround sound system designed for multi-disciplinary research. Hosted by DMARC, SpADE supports artistic and scientific investigations by faculty and student researchers from the University of Limerick. It is also open to visiting researchers.
With 32 speakers and two sub-woofers, SpADE is the largest loudspeaker array in the Republic of Ireland. SpADE is a hybrid space where practice-led arts research and technological research in or requiring spatial audio are welcome.
Researchers from the University of Limerick use SpADE to study a wide variety of fields including: auditory display, interactive sonification, music composition, musicology, music software development, psychoacoustics, haptics, interface design, and wearable computing in the sound environment. These researchers are collaborating with other musicians and scientists in Ireland and around the world in the fine arts, marine biology, chemistry, medicine, and software engineering.
