minim audioplayer volume change
Oct 23rd, 2008, 6:10pm  
hello,

how does minim work to set the volume in runtime for a audioplayer object? or even a AudioSample ?

ive tried setVolume and setGain, but none of them works directly.

One of those two *should* work, but whether or not either control is available depends on the Java implementation you are running on. You call the method on the AudioPlayer you want to change the volume of:

AudioPlayer play;

...

play.setVolume(0.5);

ive check the range values for the gain and i was able to use setGain to change the volume for the application.

as for setVolume, didnt work for the wavesignals or even audioplayer.

it said that setvolume was not supported or so, in a error message.

where is it supported after all ?

I'm having the same problem on Leopard 10.5.5 using Processing 0154 - setVolume() doesn't work. What Java implementation should I be using in order for this to work?

Also, when using setGain(), I get clicks as I change the gain. Any way to interpolate more smoothly?

best,
Zachary

Like zseldess says,

What Java implementation should we be using?

Tnx alot.

Well, I've switched to Sonia for this. Volume changes and panning are far smoother (click free).

Still wondering if there's a way to fade and pan in minim without clicks (guessing the cause of this is that the signal is not being modified at the sample rate).

Yes, if all you are doing is setting volume or pan directly, you risk clicks. If you want it to change smoothly, you either need to interpolate the value over time yourself, or try using shiftPan or shiftVolume.

As far as which Java version to use to get a Volume control, I don't really know. I can't keep tabs on those things. At some point I may do my own implementations of these controls so that it won't be JVM dependent, we'll see.

i tryed the code:


import ddf.minim.*;

Minim minim;
AudioPlayer player;

void setup(){
   minim = new Minim(this);
   player = minim.loadFile("foo.mp3");
   player.loop();

   println(player.getControlls());
}



and then, i got messages below:


[0] Master Gain with current value: 0.0 dB (range: -80.0 - 13.9794)
[1] Mute Control with current value: False
[2] Pan with current value: 0.0  (range: -1.0 - 1.0)
[3] Sample Rate with current value: 44100.0 FPS (range: 0.0 - 48000.0)


these messages mean that Gain, Mute, Pan and Sample Rate are available on AudioPlayer.

According to [0],

   player.shiftGain(-80.0, 0.0, 10000);

   player.setGain(-10.0);

   player.mute();

   player.unmute();

will go fine Smiley


Gain's unit is dB and range is -80.0 to 14.0. Note that it has very large range in contrast to Volume (0.0 to 1.0). (the range maybe depends on your environment)
