Method Detail
-
bindAudioBuffer
boolean bindAudioBuffer(AudioBuffer audioBuffer)
Description copied from class:AbstractAudioSource
Binds this AudioSource with the specified AudioBuffer.Applies only to sub-types:
- Source
- Specified by:
bindAudioBuffer
in classAbstractAudioSource
- Parameters:
audioBuffer
- The AudioBuffer to bind to this AudioSource- Returns:
- true if successful
-
changePosition
protected void changePosition(javax.vecmath.Vector3f pos)
Description copied from class:AbstractAudioSource
Change the current position of this source.- Specified by:
changePosition
in classAbstractAudioSource
- Parameters:
pos
- new position
-
setGain
public void setGain(float gain)
Description copied from interface:AudioSource
Set the gain of this AudioSource objectDefault value = 1.0f
Applies only to sub-types:
- Listener
- Source
- Specified by:
setGain
in interfaceAudioSource
- Overrides:
setGain
in classAbstractAudioSource
- Parameters:
gain
- the gain of this AudioSource
-
setPitch
public void setPitch(float pitch)
Description copied from interface:AudioSource
Set the pitch of this AudioSource objectValues are restricted from 0.5f to 2.0f, i.e. half to double
Default value = 1.0f
Applies only to sub-types:
- Source
- Specified by:
setPitch
in interfaceAudioSource
- Overrides:
setPitch
in classAbstractAudioSource
- Parameters:
pitch
- the pitch of this AudioSource
-
setReferenceDistance
public void setReferenceDistance(float referenceDistance)
Description copied from interface:AudioSource
Set the reference distance of this AudioSource object.Default value = 1.0f
The Reference Distance is one of the main parameters you have for controlling the way that sounds attenuate with distance. A Source with Reference Distance set to 5 (meters) will be at maximum volume while it is within 5 metere of the listener, and start to fade out as it moves further away. At 10 meters it will be at half volume, and at 20 meters at a quarter volume, etc ...
Applies only to sub-types:
- Source
- Specified by:
setReferenceDistance
in interfaceAudioSource
- Overrides:
setReferenceDistance
in classAbstractAudioSource
- Parameters:
referenceDistance
- the Reference Distance for this AudioSource
-
setOffset
public void setOffset(long offset)
Description copied from interface:AudioSource
Set the offset in which to start playback of this AudioSource.Default value = 0
Value is clamped between 0 and length of attached AudioBuffer
Applies only to sub-types:
- Source
- Specified by:
setOffset
in interfaceAudioSource
- Overrides:
setOffset
in classAbstractAudioSource
- Parameters:
offset
- the offset in samples marking the point to commence playback
-
getState
public int getState()
Description copied from interface:NamedBean
Provide generic access to internal state.This generally shouldn't be used by Java code; use the class-specific form instead (e.g. getCommandedState in Turnout). This is provided to make scripts easier to read.
- Specified by:
getState
in interfaceNamedBean
- Overrides:
getState
in classAbstractAudio
- Returns:
- the state
-
stateChanged
public void stateChanged(int oldState)

stateChanged
in classAbstractAudioSource
- Parameters:
oldState
- the former state
-

- Specified by:
cleanup
in classAbstractAudio
-
