Remarks

The VolumeShaper class is used to automatically control audio volume during media playback, allowing simple implementation of transition effects and ducking. It is created from implementations of VolumeAutomation, such as MediaPlayer and AudioTrack (referred to as "players" below), by MediaPlayer#createVolumeShaper or AudioTrack#createVolumeShaper.

A VolumeShaper is intended for short volume changes. If the audio output sink changes during a VolumeShaper transition, the precise curve position may be lost, and the VolumeShaper may advance to the end of the curve for the new audio output sink.

The VolumeShaper appears as an additional scaling on the audio output, and adjusts independently of track or stream volume controls.

Equals(Object)	Indicates whether some other object is "equal to" this one. (Inherited from Object)
GetHashCode()	Returns a hash code value for the object. (Inherited from Object)
JavaFinalize()	Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. (Inherited from Object)
Notify()	Wakes up a single thread that is waiting on this object's monitor. (Inherited from Object)
NotifyAll()	Wakes up all threads that are waiting on this object's monitor. (Inherited from Object)
Replace(VolumeShaper+Configuration, VolumeShaper+Operation, Boolean)	Replaces the current `VolumeShaperconfiguration` with a new `configuration`.

ToArray<T>()	(Inherited from Object)
ToString()	Returns a string representation of the object. (Inherited from Object)
UnregisterFromRuntime()	(Inherited from Object)
Wait()	Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>. (Inherited from Object)
Wait(Int64)	Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>, or until a certain amount of real time has elapsed. (Inherited from Object)
Wait(Int64, Int32)	Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>, or until a certain amount of real time has elapsed. (Inherited from Object)
