    refDistance: number;
    maxDistance: number;
    rolloffFactor: number;
}

About

Shared by SpatialAudioRendererOptions (defaults for all sources) and SpatialAudioSourceOptions (overrides for one source). refDistance and maxDistance also define the normalized distance used for the lowpass filter and the reverb send.

Properties

• distanceModel: SpatialDistanceModel - How the volume drops over distance. Default "inverse".
• refDistance: number - Distance at which the volume starts to drop. Within this distance the source plays at full volume. Default 50 (2D) or 1 (3D).
• maxDistance: number - Distance at which the source is inaudible. Default 1500 (2D) or 100 (3D).
• rolloffFactor: number - How fast the volume drops over distance. Default 1.
