+/**
+ * A sound generated within a room travels in many directions. The listener first hears the
+ * direct sound from the source itself. Later, he or she hears discrete echoes caused by sound
+ * bouncing off nearby walls, the ceiling and the floor. As sound waves arrive after
+ * undergoing more and more reflections, individual reflections become indistinguishable and
+ * the listener hears continuous reverberation that decays over time.
+ * Reverb is vital for modeling a listener's environment. It can be used in music applications
+ * to simulate music being played back in various environments, or in games to immerse the
+ * listener within the game's environment.
+ * The EnvironmentalReverb class allows an application to control each reverb engine property in a
+ * global reverb environment and is more suitable for games. For basic control, more suitable for
+ * music applications, it is recommended to use the
+ // TODO when PresetReverb is unhidden
+ // {_at_link android.media.PresetReverb} class.
+ * <p>An application creates a EnvironmentalReverb object to instantiate and control a reverb engine
+ * in the audio framework.
+ * <p>The methods, parameter types and units exposed by the EnvironmentalReverb implementation are
+ * directly mapping those defined by the OpenSL ES 1.0.1 Specification
+ * (http://www.khronos.org/opensles/) for the SLEnvironmentalReverbItf interface.
+ * Please refer to this specification for more details.
+ * <p>The EnvironmentalReverb is an output mix auxiliary effect and should be created on
+ * Audio session 0. In order for a MediaPlayer or AudioTrack to be fed into this effect,
+ * they must be explicitely attached to it and a send level must be specified. Use the effect ID
+ * returned by getId() method to designate this particular effect when attaching it to the
+ * MediaPlayer or AudioTrack.
+ // TODO when AudioEffect is unhidden
+ // <p> See {_at_link android.media.AudioEffect} class for more details on controlling
+ * audio effects.

+/**
+ * A sound generated within a room travels in many directions. The listener first hears the
+ * direct sound from the source itself. Later, he or she hears discrete echoes caused by sound
+ * bouncing off nearby walls, the ceiling and the floor. As sound waves arrive after
+ * undergoing more and more reflections, individual reflections become indistinguishable and
+ * the listener hears continuous reverberation that decays over time.
+ * Reverb is vital for modeling a listener's environment. It can be used in music applications
+ * to simulate music being played back in various environments, or in games to immerse the
+ * listener within the game's environment.
+ * The PresetReverb class allows an application to configure the global reverb using a reverb preset.
+ * This is primarily used for adding some reverb in a music playback context. Applications
+ * requiring control over a more advanced environmental reverb are advised to use the
+ // TODO when EnvironmentalReverb is unhidden
+ // {_at_link android.media.EnvironmentalReverb} class.
+ * <p>An application creates a PresetReverb object to instantiate and control a reverb engine in the
+ * audio framework.
+ * <p>The methods, parameter types and units exposed by the PresetReverb implementation are
+ * directly mapping those defined by the OpenSL ES 1.0.1 Specification
+ * (http://www.khronos.org/opensles/) for the SLPresetReverbItf interface.
+ * Please refer to this specification for more details.
+ * <p>The PresetReverb is an output mix auxiliary effect and should be created on
+ * Audio session 0. In order for a MediaPlayer or AudioTrack to be fed into this effect,
+ * they must be explicitely attached to it and a send level must be specified. Use the effect ID
+ * returned by getId() method to designate this particular effect when attaching it to the
+ * MediaPlayer or AudioTrack.
+ // TODO when AudioEffect is unhidden
+ // <p> See {_at_link android.media.AudioEffect} class for more details on controlling audio effects.
