After a SoundChannel is stopped, it s pretty much nished, and you can discard it. If you want to replay the sound, call play() on the Sound again, which creates a new SoundChannel. If you are streaming an audio le, you can also stop it from playing back by using the Sound object s clear() method. This not only causes the sound to stop, but it stops the download of the streamed audio le. If you want to play the sound again, you have to reinitiate the loading of the sound le before you can play it. In some cases, you ll want to quickly stop all audio playback. To handle this, you can use the nuclear option: SoundMixer.stopAll(). When you call this static method, all currently playing sounds are stopped immediately.

You ve used the play() method several times now, but I haven t explored its parameters. By using the optional parameters of play(), you can do much more with a sound. The full signature for play() is

startTime Determines the position of the playhead when the sound starts playing, in milliseconds. The default is 0; when you call play() with no arguments, the sound starts playing from the beginning.

sndTransform Sets an initial SoundTransform to modify how the sound is mixed. Can also be set after the sound starts playing. I ll discuss how to use sound transforms in the section Applying Sound Transformations.

In this section, you build a simple audio player. With just the startTime parameter of the play() method and the position property of the SoundChannel class, you can create all the standard audio player controls you know and love. I ve already beaten play() and stop() to death with a stick. With fast-forward or rewind, the goal is to jump forward or backward from the currently playing portion of the sound. To do this, you use the position property to get the current playhead position, add or subtract some value to that, and then restart the song from the new position. Pausing a sound is almost the same. Because the stop() method causes the position to be lost, you just remember the playhead position at the time the user pauses. Later, when the song is resumed, you can use the value to pick up where you left off. Example 31-3 a simple sound player example with four buttons rewind, pause, play, and fast-forward that uses the position parameter in the play() method. There is also a text eld that shows the current position and the overall time in seconds.
