Canada’s first real opera house is under construction in Toronto. For now, though, it exists in software. “In a opera house, sound is sacred. The worst nightmare is to pour the concrete, build the place, and then find out the acoustics are poor. So computer software has been heavily pressed into service to establish what kind of sound every person in the hall will hear – before the hall is built. This is something that has only become possible in the past four years, and Toronto’s opera house will be the first to receive the benefit.”
