ToneControl
ToneControl is the interface to enable playback of a user-defined monotonic tone
sequence. The JSR 135 Mobile Media API will implement public interface ToneControl.
A tone sequence is specified as a list of non-tone duration pairs and user-defined
sequence blocks and is packaged as an array of bytes. The setSequence() method
is used to input the sequence to the ToneControl.
The following is the available method for ToneControl:
-setSequence (byte[] sequence): Sets the tone sequence
VolumeControl
VolumeControl is an interface for manipulating the audio volume of a Player. The JSR 135
Mobile Media API will implement public interface VolumeControl.

StopTimeControl
StopTimeControl allows a specific preset sleep timer for a player. The JSR 135 Mobile
Media API will implement public interface StopTimeControl.
The following is a list of available methods with regards to StopTimeControl:
-getStopTime: Gets the last value successfully by setStopTime.
Volume Settings - allows the output volume to be specified using an integer
value that varies between 0 and 100. Depending on the application, this will need
to be mapped to the volume level on the phone (0-7).
Specifying Volume in the Level Scale - specifies volume in a linear scale. It
ranges from 0 – 100 where 0 represents silence and 100 represents the highest
volume available.
Mute – setting mute on or off does not change the volume level returned by the
getLevel. If mute is on, no audio signal is produced by the Player. If mute is off,
an audio signal is produced and the volume is restored.
