Auralization in slow motion

A novel auralization method, in which the propagation speed of sound is slowed down, is demonstrated with a few examples. The auralization in slow motion enables to study the details of simulated impulse responses, such as spatial distribution of early reflections and spectrum of each reflection, in great detail. It is based on a simple idea that propagation speed of sound in simulations are slowed down. The method can be applied in room acoustics design as well as in teaching of room acoustics.

The demos are computed for headphone reproduction! (fs = 48 kHz)
