i have a large sound file 10mb ogg. it wont play beacause of a ‘out of memory’. can xith stream audio data instead of loading it all into ram?

also i cant seems to find anywhere to add reverb and the other effects… :frowning:

I remember there was a discussion related to streaming issues:

http://www.java-gaming.org/cgi-bin/JGNetForums/YaBB.cgi?board=xith3d;action=display;num=1063036501, thread named “Sound”.

This was at very early stage of Xith3D sound system, but I don’t know if we have some progress with streaming since that time.

strange it reads as if it can stream the audio.

i am playing the sound the same way as in the demo. and it seems to need to be all loaded into memory.

#4

The xith3d design supports streaming sources, but the ogg and wav loaders do not support it yet… if that makes sense. I will add it to the long list of things to do :slight_smile:

cool- also the setMaxDistance didnt see to work for me. i have an object that is around 80f height width depth. i set the MaxDistance to 100f and at -38f the sound still plays full volume, then at -39f it stops. any ideas?


    SoundDriver soundDriver = new SoundDriverImpl();
    soundDriver.setListenerVolume(1f);
    view.setSoundDriver(soundDriver);

on me object:


      MediaContainer mc = new MediaContainer(bSoundName); // wav filepath
      PointSound sound = new PointSound(mc, 1);
      sound.setMaxDistance(100f);
      sound.setEnable(true);

      model.addChild(sound);

cant see where i am going wrong… :frowning:

gosh this still not working… the sound turns on or off… nothing else. no 3d fade, nothing :(. sodding sod all!

anyone got any pointers? getting me down. i done this in a snap in joal. and i’ve looked at the xith src and it all looks just sweet. also the xith soundtest works! gurrr…

help! LOL :slight_smile: ;D

i got it working alittle bit- but as i get closer to the object the sound just kicks in. then fade from that point to 100%. but seems to start around 50% at max distance.

anyone?

the other problem was me being a muppet - joal seems not to work with stereo files.

#8

OpenGL does not allow distance attenuation with anything but mono sounds. I have that from the Gerin, the OpenGL main dev. It makes sense when you think about it since it needs both channels to attenuate spatially.

#9

well thats omething for another list then ;).

but whats with the sound just kicking in? when at the edge of the sound zone i would of thought the sound would start at a lvl of 0 and fade up to max volume as u got closer to the sounds location.

but it seems to load and start at around (min 0f - max 1f) 0.5f, strange. i have tryed this with your test sounds with the same results.

#10

OK sorry to say the SoundTest dont work ither. If u turn the background sound off (coss it gets in the way). and then run it. u will find when the cubes go into Z the sound cuts out before it fades to 0f.

think we have a bug. maybe a OpenAL thing- coss it looks to me like its not working.

#11

Is there a way to change playing speed (frequency) and volume through Xith3D API’s yet?

#12

anyone mind if i look into the xith sound openal stuff? i think its maybe an openal change that we not updated.

i maybe of help yet :slight_smile:

Would be really great if you can check that!

I personally interested in spatialized sound, but still use Xith3D JavaSound driver.
