Abstract

The Doppler shift is a naturally occurring phenomenon that shifts the pitch of sound if the emitting object’s distance to the listener is not a constant. These pitch deviations, alongside amplitude change help humans to localise a source’s position, velocity and movement direction. In this paper we investigate spatial audio reproduction methods to determine if Doppler shift is present for a moving sound source. We expand spatialisation techniques to include time-variance in order to produce the Doppler shift. Recordings of several different loudspeaker layouts demonstrate the presence of Doppler with and without time-variance, comparing this to the pre-calculated theoretical values.
