Sets this sound's distance gain attenuation - where gain scale factor is applied to sound based on distance listener is from sound source.

Usage

From source file:SimpleSounds.java

/**
 * Add a sound to the transform group. This takes a point sound object and
 * loads into it a sounds from a given file. The edge of the sound's extent
 * is also defined in a parameter.//  w  ww .j  ava 2 s .  co m

 * @param soundFile
