hi, have been messing around with this example for about an hour or so trying to map height value to
set the room size..not quite there. Any help getting started with this would be appreciated..
- // Panner_01.pde
- // this example demonstrates how to use the Panner object
- import beads.*;
- AudioContext ac;
- String sourceFile; // this will hold the path to our audio file
- SamplePlayer sp; // the SamplePlayer class will be used to play the audio file
- // standard gain objects
- Gain g;
- Glide gainValue;
- Reverb r; // our Reverberation unit generator
- void setup()
- {
- size(800, 600);
- ac = new AudioContext(); // create our AudioContext
- sourceFile = sketchPath("") + "Drum_Loop_01.wav";
- // Try/Catch blocks will inform us if the file can't be found
- try {
- // initialize our SamplePlayer, loading the file indicated by the sourceFile string
- sp = new SamplePlayer(ac, new Sample(sourceFile));
- }
- catch(Exception e)
- {
- // if there is an error, show an error message (at the bottom of the processing window)
- println("Exception while attempting to load sample!");
- e.printStackTrace(); // then print a technical description of the error
- exit(); // and exit the program
- }
- // we would like to play the sample multiple times, so we set KillOnEnd to false
- sp.setKillOnEnd(false);
- // as usual, we create a gain that will control the volume of our sample player
- gainValue = new Glide(ac, 0.0, 20);
- g = new Gain(ac, 1, gainValue);
- g.addInput(sp); // connect the filter to the gain
- r = new Reverb(ac, 1); // create a new reverb with a single output channel
- r.setSize(0.7); // set the room size (between 0 and 1) 0.5 is the default
- r.setDamping(0.5); // set the damping (between 0 and 1) - the higher the dampening, the fewer resonant high frequencies
- // You can also control a Reverb's early reflections and late reverb
- // to do so, use r.setEarlyReflectionsLevel(0-1); or r.setLateReverbLevel(0-1);
- r.addInput(g); // connect the gain to the reverb
- ac.out.addInput(r); // connect the Reverb to the AudioContext
- // remember, the reverb unit only outputs a reverberated signal
- // so if we want to hear the dry drums as well, then we will also need to connect
- // the SamplePlayer to the output
- ac.out.addInput(g); // connect the sp gain to the output
- ac.start(); // begin audio processing
- background(0); // draw a black background
- text("Click to hear a Reverb object in action.", 50, 50); // tell the user what to do
- }
- // although we're not drawing to the screen, we need to have a draw function
- // in order to wait for mousePressed events
- void draw(){}
- // this routine is called whenever a mouse button is pressed on the Processing sketch
- void mousePressed()
- {
- gainValue.setValue((float)mouseX/(float)width); // set the gain based on mouse position
- sp.setToLoopStart(); // move the playback pointer to the first loop point (0.0)
- sp.start(); // play the audio file
- }
