Iam using the Clip class to play the audio. Frequently i get the following exception... java.lang.IllegalArgumentException: No line matching interface Clip supporting format ULAW 8000.0 Hz, 8 bit, mono, 1 bytes/frame, is supported. The exception is thrown in the code line "Targetclip = (Clip) AudioSystem.getLine(info);" The code snippet which throws the exception is as follows... //Converting Audio Format if (format.getEncoding() != AudioFormat.Encoding.PCM_SIGNED) { System.out.println("*** Converting..."); format = new AudioFormat( AudioFormat.Encoding.PCM_SIGNED, format.getSampleRate(), format.getSampleSizeInBits()*2, format.getChannels(), format.getFrameSize()*2, format.getFrameRate(), true); // big endian stream2 = AudioSystem.getAudioInputStream(format, stream2); } printDebug("((int)stream2.getFrameLength()*format.getFrameSize()): " + ((int)stream2.getFrameLength()*format.getFrameSize())); DataLine.Info info = new DataLine.Info(Clip.class, stream2.getFormat()); // DataLine.Info info2 = new DataLine.Info(Clip.class, stream2.getFormat(), ((int)stream2.getFrameLength()*format.getFrameSize())); Targetclip = (Clip) AudioSystem.getLine(info); What could be wrong?? Why this exception is thrown? How do we solve this?? Any links, sample code OR help in any form is highly appreciate.

Thanks in advance -Sundar My best guess is that your sound card doesn't support ULAW. -- Knute Johnson email s/nospam/knute/ Back to top Sundar Guest Posted: Wed Nov 22, 2006 11:28 pm    Post subject: Re: Baffeled with IllegalArgumentException exception Quote: My best guess is that your sound card doesn't support ULAW. It doesnt look like a hardware issue, coz the exception is thrown randomly. Sometimes the program works fine and plays the audio properly. But sometimes it fails with IllegalArgumentException !. If it is a harware problem the exception will be consistent, But in reality it isnt!!. -Sundar Knute Johnson wrote: Quote: Sundar wrote: Hi, Iam using java sound API to play the audio.

If you want to post a simple test program that will show the problem, I'd be happy to play with it. -- Knute Johnson email s/nospam/knute/ Back to top Display posts from previous: All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First         AppletTalk.com Forum Index -> Java Help All times are GMT Page 1 of 1   Jump to: Select a forum Java Newsgroups----------------Java DiscussionsWeb-based java games comp.lang.java 3D Graphics API's for Java Java: Support and criticism Java System Announcements comp.lang.java.api JavaBeans Java and CORBA Java and Databases comp.lang.java.developer Java GUI Toolkits Java Help comp.lang.java.javascript JVM, native methods and hardware comp.lang.java.misc Java Language Programming Security and Java comp.lang.java.setup Java Software Tools comp.lang.java.tech ibm.software.java.linux  Non-English Java Newsgroups----------------Java Language (German)Language Java (Français)Java (Italian)  You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum Powered by phpBB © 2001, 2006 phpBB Group SEO toolkit © 2004-2006 webmedic.
