problem running example buffer.write

in General Discussion • Other • 8 months ago

helo guys!!

i am running the following example from http://www.erase.net/projects/processing-sc/examples/buffer_write

import supercollider.*; import java.util.ArrayList; import ddf.minim.*; Buffer buffer; AudioPlayer song; void setup () { buffer = new Buffer(2); buffer.read("/Users/daniel/audio/samples/acoustic/piano-chord.aif", this, "done"); } void done (Buffer buffer) { println("Buffer loaded."); println("Channels: " + buffer.channels); println("Frames: " + buffer.frames); println("Sample Rate: " + buffer.sampleRate); } void mousePressed() { buffer.write("/tmp/test.aif", "aiff", "int16", this, "written"); } void written (Buffer buffer) { println("Buffer written to disk"); /// THIS IS WHERE THE PROBLEM APPEARS ///

 Minim.start(this); song = Minim.loadFile("/tmp/test.aif"); song.play(); } void draw() { background(0); stroke(255); // shamelessly taken from an example found here: // http://code.compartmental.net/tools/minim/manual-audiosource/ if (song != null) { for (int i = 0; i < song.bufferSize() - 1; i++ ) { float x = height/4 - song.left.get(i)*50; float y = height/4 - song.left.get(i+1)*50; line(i, x, i+1, y); x = 3*height/4 - song.right.get(i)*50; y = 3*height/4 - song.right.get(i+1)*50; line(i, x, i+1, y); } } }

IT SAYS THE FUNCTION START(BUFFER_WRITE) DOES NOT EXIST.

i really have NO IDEA what the problem might be... (i am pretty new in programming)

any help please??

thank you in advance! :)

this the code from above

I would expect setup()
to start with

size(800,800);

Otherwise I can't help you

import supercollider.*;
import java.util.ArrayList;
import ddf.minim.*;
Buffer buffer;
AudioPlayer song;
void setup () {
buffer = new Buffer(2);
buffer.read("/Users/daniel/audio/samples/acoustic/piano-chord.aif", this, "done");
}
void done (Buffer buffer) {
println("Buffer loaded.");
println("Channels: " + buffer.channels);
println("Frames: " + buffer.frames);
println("Sample Rate: " + buffer.sampleRate);
}
void mousePressed() {
buffer.write("/tmp/test.aif", "aiff", "int16", this, "written");
}
void written (Buffer buffer) {
println("Buffer written to disk"); /// THIS IS WHERE THE PROBLEM APPEARS ///
Minim.start(this);
song = Minim.loadFile("/tmp/test.aif");
song.play();
}
void draw() {
background(0);
stroke(255); // shamelessly taken from an example found here:
// http://code.compartmental.net/tools/minim/manual-audiosource/
if (song != null) {
for (int i = 0; i < song.bufferSize() - 1; i++ ) {
float x = height/4 - song.left.get(i)*50;
float y = height/4 - song.left.get(i+1)*50;
line(i, x, i+1, y);
x = 3*height/4 - song.right.get(i)*50;
y = 3*height/4 - song.right.get(i+1)*50;
line(i, x, i+1, y);
}
}
}

The problem still appears in line 21 of the code though...
This is what one of the developers posted to me in another forum:

For a long time, it's been the case that you need to make an instance of Minim and use that. There aren't static functions on the class anymore. So you need to add global variable of the type Minim and then create it in setup() with new Minim(this). Then you use that instance to load the file into an AudioPlayer.

Thank you in advance for your time, i'm a newbie and in order to fix this it will probably take me a week...
