Play soundclip and generate"wind" like sound

[diablo2070]

Hi,

My knowledge in Java are very limited and I need to do a program for a project. However, I can't find how to do it.

2 things :

1)
I want to play a soundclip. It can be a wav, a mp3, whatever will be the easiest to read I don't care since I will create that file and it will never change it after. This sound will happen when a specific event happen. I download the Demo of the Java Sound API from the official Java website, but it is quite hard for me to understand how to just read a simple file.

Also, that file will be a Mono file, wich I want to be able to gage the volume in 3D (2 fronts, 2 rears)... I don't know if something like that is possible in Java.. especially with my knowledge. In the worst case, a left/right balance could do it.

2)
I need to generate a sound that will give a wind effect that will be more or less loud depending on parameters coming from an external sensor. I have absolutly no idea how to do that, but i though maybe i could use the MIDI sounds using an instrument like "helicopter" or something like that.


The first part is the most important one, it is essential to the project.

Any idea :confused: I'm really lost with all that.

Have a look at the static method Applet.newAudioClip( ... ); it loads a clip and you can play, loop and stop it. Personally I still wonder why this is a static method in the Applet class.

kind regards,

I just tried it, and trying to read a song converted to wav makes a very slow reading, like if a buffer was always full or something like that :P and one of my core is almost at 85% (i have a T9600 wich should be far enough :P). Any idea why it does that?

Edit : Ok well I just loaded a short clip (about 1 sec.) and it looks fine.

WAVs are huge and java doesn't natively decode mp3. You can look at JLayer for mp3 decoding, but thats quite a bit of work/learning curve. For simple games and the like, WAV and AIFF are fine - assuming you don't have any huge audio tracks.

The method Applet.newAudioClip( ... ) works fine for my needs, but I really can't find a way to control gain. I'm leaving the idea of surround, but i would at least want to be able to control gain. I've searched a lot on the internet but I can't find any way to control gain with that method. Anyone has an idea?

Thanks

There aren't many transformation controls built in that I know of (there could be some, I have not used them before) but there are many third party libraries that might be helpful.
