Doppler shift in VR is modeled by dynamically adjusting sample rate or propagation delay
Evidence
High-speed movement of the source relative to the listener in the physical world results in the Doppler effect, where the perceived pitch of the sound changes with the change in distance between the listener and the source. This effect can be modelled simply in the reproduction of recorded source signals with dynamic sample rate conversion. Alternatively, the effect can be implemented by updating the sound propagation delay correctly. The delay is computed dynamically from the distance between the avatar and the source. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 2567
