surround sound

Dafar · September 6, 2009 at 11:30 PM

Hello Guys,

I´m wondering if its possible work with surround 5.1 mp3 files or if i can work with 4 different channels (mono files) and put them around the scene as sound hotspots. When the user turn the scene, start hearing the arounder sound (but the 4 files must start at the same time and in synchronicity). Is it possible?

Thank you!!

Hi,

I'm not sure but I think Flash doesn't support more than 2 channels in a mp3 file...
using separate mono (or stereo) files would be possible but if they will start really synchrony can't be not guaranteed...

best regards,
Klaus

Hello Klaus,

How can i write the code to make all hotspot sounds start playing automaticaly?

Could you please help me in order to make some tests?

Best Regards,

Daniel

Hi,

preloading the sounds before starting playing them could help a bit I think
(but I'm don't know how the Flashplayer will finally handle the loading internally),

e.g. this would be the code to preload the sound files and start playing them after 2 seconds:

Code

<krpano onstart="action(startsounds_step1);">


<plugin name="soundinterface" url="soundinterface.swf" preload="true" />


<action name="startsounds_step1">
  preloadsound(sound1.mp3);
  preloadsound(sound2.mp3);
  preloadsound(sound3.mp3);
  preloadsound(sound4.mp3);
  delayedcall(2, action(startsounds_step2));
</action>


<action name="startsounds_step2">
  playsound3D(s1, sound1.mp3, -45.0, 0, 90.0, 1.0, 0);
  playsound3D(s2, sound2.mp3, +45.0, 0, 90.0, 1.0, 0);
  playsound3D(s3, sound3.mp3, -135.0, 0, 90.0, 1.0, 0);
  playsound3D(s4, sound4.mp3, +135.0, 0, 90.0, 1.0, 0);
</action>

Great Klaus,

After reading the code it makes a lot of sense (of course, hehe)

I´ll make a test with the same file repeated (renamed 4 times) to see if it plays out ou in sync).

Thank you again!!

Hello, Klaus!
I used your example as described above.
But in some cases I desync audio tracks. I do not know how to fix it. It is even possible?
Sorry for my English, I use Google translator

Code

<action name="startsounds_step1">
  preloadsound(sounds/sound1.mp3);
  preloadsound(sounds/sound2.mp3);
  preloadsound(sounds/sound3.mp3);
  delayedcall(2, action(startsounds_step2));
	</action>


	<action name="startsounds_step2">
  playsound3D(s1, sounds/sound1.mp3, -35, -1, 30, 1.5, 0);
  playsound3D(s2, sounds/sound2.mp3, -10,  9, 30, 1.5, 0);
  playsound3D(s3, sounds/sound3.mp3,  10, -2, 30, 1.5, 0);


  playsound3D(s4, sounds/sound1.mp3, -35, -1, 300, 1, 0);
  playsound3D(s5, sounds/sound2.mp3, -10,  9, 300, 1, 0);
  playsound3D(s6, sounds/sound3.mp3,  10, -2, 300, 1, 0);
