not to mention that ogg has 200kbps over the 320kbps limit mp3 does. The only reason I use mp3 is for music I get off itunes or opensource music. However, a lot are using flac which does get a bit big. ogg at full is quite big but still.

Hi, Well, that definitely gives me a clearer picture of what your aiming for. Before I get into the technical details of working with audio in Java I would like to point out that ogg might be a better choice than mp3. The reason I say that is I'm not sure if you are aware of this but mp3 is a copyrighted and proprietary format and if you intend to use it in a commercial game or similar you have to pay money to use the mp3 file format. That's one major reason many game developers etc are moving to ogg which has the same or better quality and is licensed under an open source license. The other reason I point out ogg is that many audio libraries are now supporting ogg and moving away from mp3 do to those same licensing issues. Now, one thing you did not indicate is what OS you are developing this game for. Windows, Mac, and Linux all have different audio APIs available to you so I'm going to be shooting in the dark on which API would be best for your specific needs here so I'll give you a list of pros and cons for each possibility. As of Java 1.4.2 and later Java ships with a basic sound API in the javax package that is well suited for most games. It can not handle compressed file types such as wma, mp3, or ogg, but for wav files its a decent enough API for what you want to do. Using the javax.sound.sampled.Clip class you can load sound clips, pan them, control gain, change pitch/frequency, and even handle some simple DSP effects like echo too. Besides shipping with the Java runtime environment it works out of the box with Windows, Mac, and Linux JRE implementations so its really the way to go for anyone wishing to write a cross-platform game using Java. If you need I can probably whip up some code samples to show you how to initialize the sound system and load and play a sound clip using the Java Sound API. Next is Joal which I've mentioned before. Joal is a Java wrapper for the OpenAL cross-platform library. The principle advantage of Joal is that you can write applications that have 5.1 and 7.1 surround sound audio, have 3d virtualization, as well as handle pitch, gain, and so forth using OpenAL. The downside here is that it looks like overkill for your application and OpenAL doesn't have a basic 2d pan control. Its all 3d audio or nothing. :D Another option is JSDL which is a Java wrapper for the SDL libraries. I don't know if it is actively being maintained, is up to date, but one thing JSDL can do for you is help you access SDL Mixer. SDL Mixer isn't a really advanced audio library but it is usually very simple to work with. It has basic 2d stereo panning, allows you to change the volume/gain of files, and supports a number of compressed file types such as ogg and mp3 as well as wav, aif, and so on. I've recently began using SDL Mixer in my own projects and the only disadvantage is that you can't change the pitch of files on the fly and it doesn't have many DSP effects. Otherwise its a decent audio library for a 2d side-scroller etc. Finally, there is FMOD Ex. This library is a commercial API so it may cost depending on weather or not you intend to use it commercially. The advantage here is FMOD has everything you could want including 2d stereo panning, 3d audio virtualization, ability to change the pitch and gain of the sounds, handles several audio formats such as mp3, ogg, wma, wav, aif, and has many built in DSP effects. If you are developing this game for Windows you can access FMOD via a standard com wrapper. If you are writing a game for Mac OS or Linux you will have to write a Java wrapper for FMOD using the Java native interface or hunt around for an existing wrapper. The only disadvantage to using FMOD I have ever found is that it is only free for free games. If you want to use it in a commercial game you will have to pay licensing fees. There are a lot of other options here besides those mentioned above but you'd probably have to dig up documentation for Java or write custom JNI wrappers for them as I don't know if there are any existing Java wrappers out there for them. So I decided to give you the most common options available for you. Cheers!
