2.4.4 The Environment

The environment defines global parameters that govern how sound is processed within the 3D modeling space.

Procedure: doppler-factor

Return the current doppler factor.

Procedure: speed-of-sound

Return the current speed of sound.

Procedure: distance-model

Return the current distance model.

Possible return values are:

Procedure: set-doppler-factor! doppler-factor

Change the doppler factor to doppler-factor.

Procedure: set-speed-of-sound! speed-of-sound

Change the speed of sound to speed-of-sound.

Procedure: set-distance-model! distance-model

Change the distance model to distance-model. Valid distance models are:
