i'm I am using the minim library to play a wav, but i wonder if I can access the data file or object data for draw the all file on the screen. The buffer can be read using minim, but I need read all the wav file data for i can draw on the screen.

What exactly do you wish to draw? If you just need the waveform data, you can get it fairly easy. If you have an AudioPlayer named player, for instance, player.left.get(int dataPoint) and player.right.get(int dataPoint)get you the data for the left and right audio. To draw the waves for both the right and left audio streams (and this is straight from the example sketches for the minim library, specifically from LoadFile), do this:

for(int i = 0; i < player.left.size()-1; i++)
{
line(i, 50 + player.left.get(i)*50, i+1, 50 + player.left.get(i+1)*50);
line(i, 150 + player.right.get(i)*50, i+1, 150 + player.right.get(i+1)*50);
}

This draws the waveform in a rectangle 200 pixels tall and as wide as the audio buffer you specified in player=minim.loadFile("blablabl.wav",int audiobuffer);

Hope this helped!

the fisrt image is the fft audio, the second image is the buffer audio and last image is the wave form all audio file.

This code is make for me, but the last image is read directly from my hard disk. i wonder if i can acces to minim object in memory ram for draw the same wave.
