Class soundmodel.SonicObject 

java.lang.Object
   |
   +----soundmodel.SonicObject
public class SonicObject
extends Object
Vibration model of object. After creating a SonicObject you can obtain its sound through getSound(), which give you a mu-law encoded byte array of the sound in response to a force (encoded as an array of double). This byte array can be used for rendering with sun.audio.*, or you do with it what you want. Has some default simple sound, and is intended to be subclassed for different types of models.

Variable Index

o ampl
o decayRate
o freq
o max_short_ampl
o nf

Constructor Index

o SonicObject()
Create and initialize SonicObject

Method Index

o getSound(double, double[], double)
At sampling rate srate (must be 8012 now) apply external local force sampled in force[].
o getSound(double, double[], double, double, double)
At sampling rate srate (must be 8012 now) apply external local force sampled in force[].
o initSonicObject()
Init SonicObject with some meaningless sounds
o setMax_short_ampl(int)
Set maximum value of byte array of generated sound.
o setNf(int)
Set number of frequency modes

Variables

o freq 
 protected double freq[]
o decayRate 
 protected double decayRate[]
o ampl 
 protected double ampl[]
o nf 
 protected int nf
o max_short_ampl 
 protected double max_short_ampl

Constructors

o SonicObject 
 public SonicObject()
Create and initialize SonicObject

Methods

o initSonicObject 
 public void initSonicObject()
Init SonicObject with some meaningless sounds

o setNf 
 public void setNf(int n)
Set number of frequency modes

o setMax_short_ampl 
 public void setMax_short_ampl(int val)
Set maximum value of byte array of generated sound. Should be less than 2^15 if you want multiple sounds to add up together. Default is 10000

o getSound 
 public byte[] getSound(double srate,
                        double force[],
                        double dur)
At sampling rate srate (must be 8012 now) apply external local force sampled in force[]. Duration of everything is dur. If dur longer than time of force[] will pad with silence at end. Write to byte array. Equalize by first writing to double array and then scaling to (short). Maximum value of sound is max_short_ampl.

o getSound 
 public byte[] getSound(double srate,
                        double force[],
                        double dur,
                        double fscale,
                        double dscale)
At sampling rate srate (must be 8012 now) apply external local force sampled in force[]. Duration of everything is dur. If dur longer than time of force[] will pad with silence at end. Write to byte array. Equalize by first writing to double array and then scaling to (short). frscale and dscale scale frequencies and damping by a constant factor. Maximum value of sound is max_short_ampl.
