public class ConeSound
The ConeSound node object defines a PointSound node whose sound source is directed along a specific vector in space. A ConeSound source is attenuated by gain scale factors and filters based on the angle between the vector from the source to the listener, and the ConeSound's direction vector. This attenuation is either a single spherical distance gain attenuation (as for a general PointSound source) or dual front and back distance gain attenuations defining elliptical attenuation areas. The angular filter and the active AuralAttribute component filter define what filtering is applied to the sound source. (See AuralAtttribute class for more details on filtering.) This node has the same attributes as a PointSound node with the addition of a direction vector and an array of points each containing: angular distance (in radians), gain scale factor, and filter (which for now consists of a lowpass filter cutoff frequency). Similar to the definition of the back distance gain array for PointSounds, a piecewise linear curve (defined in terms of radians from the axis) specifies the slope of these additional attenuation values.
Distance Gain attuation
Use PointSound setDistanceGain() method to set the front distance attenuation array separate from the back distance attenuation array. A front distance attenuation array defines monotonicallyincreasing distances from the sound source origin along the position direction vector. A back distance attenuation array (if given) defines monotonicallyincreasing distances from the sound source origin along the negative direction vector. The two arrays must be of the same length. The backDistance[i] gain values must be less than or equal to the frontDistance[i] gain values.
Gain scale factors are associated with distances from the listener to the sound source via an array of (distance, gainscalefactor) pairs. The gain scale factor applied to the sound source is the linear interpolated gain value between the distance value range that includes the current distance from the listener to the sound source.
The getDistanceGainLength method defined for PointSound returns the length of the all distance gain attenuation arrays, including the back distance gain arrays. Arrays passed into getDistanceGain methods should all be at least this size.
Direction Methods
Angular Attenuation
This attenuation is defined as a triple of (angular distance, gainscalefactor, filter). The distance is measured as the angle in radians between the ConeSound's direction vector and the vector from the sound source position to the listener. Both the gain scale factor and filter applied to the sound source is the linear interpolation of values between the distance value range that includes the angular distance from the sound source axis.
If this is not set, no angular gain attenuation or filtering is performed (equivalent to using an angular gain scale factor of 1.0 and an angular filter of Sound.NO_FILTER for all distances).
If angular distance from the listenersoundposition vector and a sound's direction vector is less than the first distance in the array, only the first gain scale factor and first filter are applied to the sound source. This creates a conical region around the listener within which the sound is uniformly attenuated by first gain and first filter in the array.
If the distance from the listenersoundposition vector and the sound's direction vector is greater than the last distance in the array, the last gain scale factor and last filter are applied to the sound source.
Distance elements in this array of points is a monotonicallyincreasing set of floating point numbers measured from 0 to p radians. Gain scale factors elements in this list of points can be any positive floating point numbers. While for most applications this list of gain scale factors will usually be monotonicallydecreasing, they do not have to be. The filter (for now) is a single simple frequency cutoff value.
The getAngularAttenuationArrayLength method returns the length of the angular attenuation arrays. Arrays passed into getAngularAttenuation methods should all be at least this size.
