jAudio Changes

jAudio users,

jAudio will no longer be released as a file release. Instead, it is a git only distribution. Use 'git clone git://git.code.sf.net/p/jaudio/git' to retrieve the latest project files. Preferably, use the github version under dmcennis. There are many changes in the master branch including internationalization, initial work on Android library, and a new GUI. Many new features are present and many old ones have had a cleaning. New results from this extractor may not match the old.... read more

adding mp3 support

To read mp3's in jAudio add jlayer.jar, tritonus_share.jar, and tritonus_mp3.jar to your classpath and restart jAudio. Likewise, to read ogg files, add tritonus_share.jar tritonus_vorbis.jar and jorbis.jar. Full instructions are at: http://www.tritonus.org/plugins.html

Unfortunately, I am still debugging my Java environment and am having trouble getting it to work on my system, so they are not included in jAudio 1.0.4. Others have no problems with this setup.

Access problems

Please be patient if you have problems getting assistance or with bugs on this project. I am having trouble receiving emails. Furthermore, I cannot access Sourceforge (including through ssh and https) directly and the sf.net domain is rejected entirely. Whats happening between me and the distribution server is unknown as someone must unencrypt and encrypt the connection for this to happen allowing openings for 3rd party modifications to occur.... read more

I have received reports of CVS archives more recent than 0.4.5. While a jar file exists in another project named 0.5, it was renamed 0.4.5 for release. The source code described in emails to me is a major release change. I am not the author and it is not located on the jaudio project or website.

jAudio Problems

A number of bugs have being linked to hacked copies of various jar files previously. More recent bugs appear to be the result of a hacked compiler. I am still tracking down the compiler errors, but have been able to isolate and confirm that a broken compiler is responsible for problems in other projects. As a work around, please use the CVS source and compile yourself. A public source code release is in the works.
