PannerNode: distanceModel property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since April 2021.

The distanceModel property of the PannerNode interface is an enumerated value determining which algorithm to use to reduce the volume of the audio source as it moves away from the listener.

The possible values are:

linear: A linear distance model calculating the gain induced by the distance according to: 1 - rolloffFactor * (distance - refDistance) / (maxDistance - refDistance)
inverse: An inverse distance model calculating the gain induced by the distance according to: refDistance / (refDistance + rolloffFactor * (Math.max(distance, refDistance) - refDistance))
exponential: An exponential distance model calculating the gain induced by the distance according to: pow((Math.max(distance, refDistance) / refDistance, -rolloffFactor).
