hi,
this sounds totally different in browser and i don't know why...
BSound X;
int N = 12000;
float notes[] = {
20.0, 19.0, 18.0, 23.0, 20.0, 19.0, 18.0, 22.3,
20.0, 19.0, 18.0, 23.0, 20.0, 19.0, 18.0, 23.0,
20.0, 19.0, 18.0, 23.0, 20.0, 16.5, 18.0, 23.0,
20.0, 19.0, 18.0, 23.0, 20.0, 19.0, 18.0, 6.0};
int note = 0;
void setup()
{
size(400, 400);
background(#FF6600); //why orange?
X = new BSound(N);
}
void loop()
{
for (int n=0; n<N; n++) {
X.samples[n] = int(64*sin((PI/N)*float(n))); //original signal
X.samples[n] *= sin(float(n*PI/float(notes[note%notes.length]))); //add notes
X.samples[(n*mouseX)%N] += 0.2*sin(PI/(mouseY/190)*n); // add noise }
note++;
repeat(X);
}
help!

additional audio info
western notation scale
Code:
String[] names = { "A", "Bb", "B", "C", "C#", "D", "D#", "E", "F", "F#", "G" };
float[] frequencies = { 440, 466.16, 493.88,
523.25, 554.37, 587.33,
622.25, 659.26, 698.26,
739.99, 783.99 };

more crap
Code:
// Western Music in a Nutshell
// by Madmerv ; adaptation of original applet by Dara
BSound X;
int N = 44100; // 44.1khz
String[] names = { "A", "Bb", "B", "C", "C#", "D", "D#", "E", "F", "F#", "G" };
float[] freq = { 440, 466.16, 493.88,
523.25, 554.37, 587.33,
622.25, 659.26, 698.26,
739.99, 783.99 };
int note = 0;
int octave = 1;
void setup()
{
size(freq.length^2, freq.length^2);
for ( int o = 1; o < freq.length; o++ ) {
for ( int j = 0; j < freq.length; j++ ) {
fill(50+j*(freq.length));
rect(j*freq.length,o*freq.length,
j*freq.length+(freq.length), width);
}
}
X = new BSound(N);
}
void mousePressed()
{
note = (mouseX/freq.length);
octave = (mouseY/freq.length);
println("Note: "+names[note]+" Octave: "+octave+"/"
+freq.length+" Frequency: "
+freq[note]*octave+" Mouse(x,y): "+mouseX+","+mouseY);
for (int n=0; n<N; n++) {
X.samples[n] = int(64*sin((PI/N)*float(n))); //original signal
X.samples[n] *= sin(float(n*PI/float((freq[note]*octave)))); //add notes
//X.samples[(n*mouseX)%N] += 0.2*sin(PI/(mouseY/190)*n); // add noise
}
play(X);
}
void loop() {}
