Help with AudioPlayer

joesteve51

I'm having trouble playing multiple sound files with the Minim audio player. Currently, I have an array of 3 AudioPlayers all initialized with separate audio files. I have a loop that goes to each cell of the array and plays the audio file.

  minim = new Minim(this);
  for (int i = 0 ; i < NUM_WAVS ; i++) {
    snd[i] = minim.loadFile(i+".mp3");
  }
  mLong = new Minim(this);
  for (int l = 0 ; l < LONG_WAVS ; l++) {
    sndlong[l] = mLong.loadFile("long"+l+".mp3");
  }
  mDrone = new Minim(this);
  for (int d = 0 ; d < DRONE_WAVS ; d++) {
    drone[d] = mDrone.loadFile("drone"+d+".mp3");
  }

The last AudioPlayer (mDrone) doesn't play unless I delete one of the first two, than it plays fine. So I know it can read the mp3s and play them. Will AudioPlayer only allow you 2 players?

Anybody know how to fix it?

Thanks

It sounds like the issue I had in Ubuntu. If that's the case, this may help: https://github.com/hamoid/Fun-Programming/blob/master/scripts/fix_sound.sh

thxs for reply hamoid, i'm using osx (& processing 2.0.3); do u think the same problem could exist on this platform?

BTW I do get 2 separate audio files playing together. Just can't get a 3rd playing.

Ah then it must be something different I think. Similar symptoms though :)

What values do you have in NUM_WAVS, LONG_WAVS and DRONE_WAVS? Are you maybe loading too many of them? Have you initialised the snd, sndlong and drone arrays? You say you have an array of AudioPlayers, but I see three arrays... is that what you want?

minim has 25 mp3s mLong has 8 mp3s drone has 3 longer mp3s

i've initialised snd, sndlong and drone. & I know the code is correct as if i delete snd, the other two play; Or if i delete sndlong, the other two play; otherwise as it is just the first two (snd, sndlong) play.

whichever i put as last doesn't play. So (as above) in this order; 1. minim 2. mLong 3. mDrone

mDrone doesn't play. But if I move mDrone to appear first, it does and mLong doesn't play.

mDrone = new Minim(this);
for (int d = 0 ; d < DRONE_WAVS ; d++) {
  drone[d] = mDrone.loadFile("drone"+d+".mp3");
}
minim = new Minim(this);
for (int i = 0 ; i < NUM_WAVS ; i++) {
  snd[i] = minim.loadFile(i+".mp3");
}
mLong = new Minim(this);
for (int l = 0 ; l < LONG_WAVS ; l++) {
  sndlong[l] = mLong.loadFile("long"+l+".mp3");
}

Maybe you could try reduce each array to 1 element to find out if it's related to the number of sounds, or the number of arrays. If loading 1 of each kind works, increase the numbers until it fails. Or maybe the word "minim" is somehow reserved? Does increasing the available ram in the Processing settings help?

Thanks hamoid, it seems like it is an issue with the number of sounds I can load. I've cut it back to 30 audio clips and all three audio players now work together.

many thanks for your help

Hi did this allow the tracks to be played at the same time? Could you show the whole code? thanks
