Constant Field Values

soundData

protected javax.media.j3d.MediaContainer soundData

sound data associated with sound source

soundType

protected int soundType

sound data associated with sound source

gain

protected float gain

Overall Scale Factor applied to sound gain.

rateScaleFactor

protected float rateScaleFactor

Overall Scale Factor applied to sound.

Since:

Java 3D 1.3

loopCount

protected int loopCount

Number of times sound is looped/repeated during play

DURATION_UNKNOWN

public static final int DURATION_UNKNOWN

See Also:

Constant Field Values

duration

protected long duration

numberOfChannels

protected int numberOfChannels

mute

protected boolean mute

vworldXfrm

protected javax.media.j3d.Transform3D vworldXfrm

vwXfrmFlag

protected boolean vwXfrmFlag

position

protected javax.vecmath.Point3f position

attenuationDistance

protected double[] attenuationDistance

attenuationGain

protected float[] attenuationGain

dirtyFlags

protected int dirtyFlags

dirty flags denoting what has changed since last rendering

direction

protected javax.vecmath.Vector3f direction

The Cone Sound's direction vector. This is the cone axis.

backAttenuationDistance

protected double[] backAttenuationDistance

Pairs of distances and gain scale factors that define piecewise linear gain BACK attenuation between each pair. These are used for defining elliptical attenuation regions.

backAttenuationGain

protected float[] backAttenuationGain

angularDistance

protected double[] angularDistance

Directional Sound's gain can be attenuated based on the listener's location off-angle from the source source direction. This can be set by three parameters: angular distance in radians gain scale factor filtering (currently the only filtering supported is lowpass)

angularGain

protected float[] angularGain

NO_FILTERING

public static final int NO_FILTERING

Distance Filter Each sound source is attenuated by a filter based on it's distance from the listener. For now the only supported filterType will be LOW_PASS frequency cutoff. At some time full FIR filtering will be supported.
