Start and stop sounds in Java

Similar to this question, I would like 开发者_如何学Pythonto play a WAV file in a Java application - however, I would also like the ability to pause, resume, and restart the sound. I'm guessing I can restart by pausing and then just creating a new sound, but how would I pause and resume in the first place?

Note that my sound is ~15minutes and 152.8mb. If there is a way to do this with an MP3 file (same length, 20.8mb) that would be even better.

For playing WAV files, see the answers to this question:
Problem with Javas Audio Clips on frequent playback of beep sounds

For playing MP3s, you can use JLayer which is a fairly small jar (100k I think, maybe smaller) that you can bundle with your application.

Here's a fairly decent example of how to use it:
MP3.java (from How to play an MP3 file in Java)

/*************************************************************************
 *  Compilation:  javac -classpath .:jl1.0.jar MP3.java         (OS X)
 *                javac -classpath .;jl1.0.jar MP3.java         (Windows)
 *  Execution:    java -classpath .:jl1.0.jar MP3 filename.mp3  (OS X / Linux)
 *                java -classpath .;jl1.0.jar MP3 filename.mp3  (Windows)

The javax.sound.sampled.Clip would be ideal for this, except for the fact that most implementations of Clip will not load more than 2 seconds of stereo, 16 bit, 44.1KHz sound! For that reason I developed BigClip. BigClip can handle sounds that are as big as the available memory.

Note that my sound is ~15minutes and 152.8mb. If there is a way to do this with an MP3 file (same length, 20.8mb) that would be even better.

Sure thing. As mentioned in the JavaSound tag info page..

MP3 decoding support

The Java Sound API does not support many formats of sampled sound internally. In a 1.6.0_24 Oracle JRE getAudioFileTypes() will generally return {WAVE, AU, AIFF}. An MP3 decoder at least, is close by. The mp3plugin.jar of the Java Media Framework supports decoding MP3s.

I currently use BigClip & the mp3plugin.jar Jar in the DukeBox player. Given 1024Meg of memory, it can easily load both the 17:12 of the 1812 Overture, & 15:38 of Bolero (the two longest tracks in my favorites play list). I mention 'both' since it will load the next track while playing the current one.

As an aside, beware of looking at code that mentions the sun.audio packages (mentioned in both linked threads). This package and/or it's classes might be moved or removed in the next release (at Oracle's discretion) & have not been necessary since Java 1.3.
