Java playing audiofiles

Newbie & Debugging Questions
#1

Hi. I got an audiorelated problem in Java:
I know how to play an audiofile with AudioClip,
but there is no option to stop the Audioclip while playing and resume it after a few seconds.
I also need to know how much of it is left to play, has been played etc.
Is there a java-class that offers these methods and not only a play() and stop() ?

There is more advanced sound class to produce sound in java, google for it

about AudioClip:
you can play/stop it that’s all (http://java.sun.com/j2se/1.4.2/docs/api/java/applet/AudioClip.html)
to know how much has been played you can do something like that
start=System.currentTimeMillis();
a.play()
//than later use playingtime=System.ucrrentTimeMillis()-start;

you can mix multiple audio file by doing:
a.play()
a2.play

you can simulate volume using a little trick:
create 5 AudioClip using same source file
than to play the sound with volume=3 do
a1.paly()
a2.play()
a3.play()

and so … for volume =1
a1.play()

finally if you like challenge you can try to produce/get a better control using sinewave as source file for multiple AudioClip and try to produce the sound using FFT :slight_smile: but finally you better use something like that http://java.sun.com/j2se/1.4.2/docs/api/javax/sound/sampled/AudioSystem.html

below a sample source code showing how to control volume with AudioClip

it use 5 different sourcefiles
SOUND0.WAV
SOUND1.WAV
SOUND2.WAV
SOUND3.WAV
SOUND4.WAV

to be compatible with JVM 1.1+ but using newAudioClip() you can use only one source file
SOUND.WAV

	public void paint(Graphics g)

}

EDIT:
using 4 differents sources files with differents volume could enable you to change sound volume from 0 to 15

your sound just have to match the below rule:
sound0.wav (volume==1)
sound1.wav (volume==2)
sound2.wav (volume==4)
sound4.wav (volume==8)

then using binary representation of your volume you can play the sound at any volume between 0 and 16 :
sound0 and sound4 for volume=9
sound0 and sound1 and sound2 a for volume=7
etc…
