mp3 and midi simultaneously

[alexmelyon]

Hello I have a problem with the sound. In memory simultaneously hold multiple MIDlet mp3 files. But still I have to play midi sounds. Work individually and mp3, and midi. But if you play them with the following happens:

javax.microedition.media.MediaException: AUD
null

Is it possible to play two types of sounds at once? And how?

Hi alexmelyon,

It is possible to play two types of sounds at once on devices that supports Audio Mixing. You can check if your device supports Audio Mixing with the system property supports.mixing.

if(System.getProperty("supports.mixing"))
{
	System.out.println("Audio mixing supported");
}

Ok. I have the "supports.mixing = true", but an exception occurs. And the Nokia SDK, and the real device.
well, not. everything is fine. I just do not have enough memory for simultaneous loading and pre-fetch all the sounds.

Could you give some more information where the exception is thrown and a code snippet of your code. What device and SDK are you using?

You could also check the Multimedia - Media Sampler example and try if it works to play the midi file and the wav file simultaenously on your device.

I have SDK 1.1 and my code was as follows:
try{
for(int i=0;i<SOUNDS_LENGTH;i++)
{
effectsPlayers[i]=Manager.createPlayer (getClass ().getResourceAsStream (effectsFileNames [i]), "audio/mp3");
effectsPlayers[i].realize();
effectsPlayers[i].prefetch();//this line throws an exception
}
}
catch(MediaException e)
{
e.printStackTrace();
}
catch(IOException e)
{
e.printStackTrace();
}

Hi alexmelyon,

So if I understand you correctly the exception comes because you are running out of memory. Is that so?

Yes. and even if you do not use player.close () in five minutes, the application throws OutOfMemory. so that the player to observe the life cycle is very important. I've already figured out the task. here as something necessary to mark a thread closed? I have not found anything like it.
