The JRE, the sound, or the code?
in [Java Help]
|
From: Andrew Thompson on 4 Oct 2009 22:46 I am having a devil of a time trying to develop a new sound format. After abandoning my earlier efforts on the basis that I could not reconstruct the binary representation to a usable sound, I revisited the problem today and found my local JREs do not seem to play the *original* sound that I am converting, correctly. Which leaves me to wonder whether it is the sound, the code or the JRE that is the problem. The code is .. <sscce> import java.net.URL; import javax.sound.sampled.*; public class LoopSound { public static void main(String[] args) throws Exception { URL url = new URL( "http://pscode.org/media/leftright.wav"); Clip clip = AudioSystem.getClip(); AudioInputStream ais = AudioSystem. getAudioInputStream( url ); clip.open(ais); clip.loop(5); } } </sscce> The sound is located at the URL shown above. It was made using Java sound, is 2 seconds in duration, stereo, and should fade between 441 Hz in one channel, to 882 Hz in the other, and back again. When I play it in the system default player, the Totem Movie Player v. 2.24.3, it sounds as I expect. Does it play OK for you? (And as an aside) It should be loopable without any perceptible 'click' at the loop points. Totem loops it but has a noticeable click. Does it loop smoothly for you? -- Andrew T. pscode.org

There were some changes made in Java Sound in 1.5 that changed one of the threads to a daemon. So when your program ends so does the sound. Try putting a sleep after the loop and it will be obvious. What you need to do is add a LineListener and wait until you get a STOP LineEvent before you end your main thread. -- Knute Johnson email s/nospam/knute2009/ -- Posted via NewsDemon.com - Premium Uncensored Newsgroup Service ------->>>>>>http://www.NewsDemon.com<<<<<<------ Unlimited Access, Anonymous Accounts, Uncensored Broadband Access

Following Knute's advice now has it working, it loops without clicking. -- And loving it, -Qu0ll (Rare, not extinct) _________________________________________________ Qu0llSixFour(a)gmail.com [Replace the "SixFour" with numbers to email me]

The quick and dirty fix is to pop a JOptionPane. And to answer my own (second) question, it seems to loop without any ugly clicks. Thanks to you both. -- Andrew T. pscode.org |
