Hello, good evening,
In my code, I would like to have a single line that moves with my music and not that new lines are formed, what can I do to make this not happen? Thanks
import processing.sound.*;
SoundFile sample;
Waveform waveform;
int samples = 100;
float r;
float g;
float b;
float a;
float diam;
float x;
float y;
void setup(){
size(1000, 1000);
background(0);
smooth();
sample = new SoundFile(this, "Maroon 5 - Nobody's Love.wav");
sample.loop();
waveform = new Waveform(this, samples);
waveform.input(sample);
}
void draw() {
r = random(255);
g = random(255);
b = random(255);
a = random(255);
diam = random(15);
x = random(width);
y = random(height);
noStroke();
fill(r,g,b,a);
ellipse(x,y,diam,diam);
strokeWeight(1);
waveform.analyze();
beginShape();
for(int i = 0; i < samples; i++){
// Draw current data of the waveform
// Each sample in the data array is between -1 and +1
vertex(
map(i, 1, samples, 0, width),
map(waveform.data[i], -1, 1, 0, height)
);
}
endShape();
}
Thanks for the tip. I’ve already added a few more lines of code to declare a smoothing factor to smooth out sudden changes in amplitude, just like in this example of Peak Amplitude, but nothing has changed
import processing.sound.*;
SoundFile sample;
Waveform waveform;
Amplitude rms;
float smoothingFactor = 0.25;
float sum;
int samples = 100;
float r;
float g;
float b;
float a;
float diam;
float x;
float y;
void setup(){
size(1000, 1000);
background(0);
smooth();
sample = new SoundFile(this, "Maroon 5 - Nobody's Love.wav");
sample.loop();
rms = new Amplitude(this);
rms.input(sample);
waveform = new Waveform(this, samples);
waveform.input(sample);
}
void draw() {
r = random(255);
g = random(255);
b = random(255);
a = random(255);
diam = random(15);
x = random(width);
y = random(height);
noStroke();
fill(r,g,b,a);
ellipse(x,y,diam,diam);
strokeWeight(1);
waveform.analyze();
sum += (rms.analyze() - sum) * smoothingFactor;
float rms_scaled = sum * (height/2) * 5;
beginShape();
for(int i = 0; i < samples; i++){
// Draw current data of the waveform
// Each sample in the data array is between -1 and +1
vertex(
map(i, 1, samples, 0, width),
map(waveform.data[i], -1, 1, 0, height)
);
}
endShape();
}
Good afternoon,
I am very confused with this question of mine and I cannot solve it, can someone help me? I am really upset, because I have to deliver this work tomorrow. I was really grateful
I also have to meet a deadline tomorrow morning for work.
That is life.
Don’t waste time (yours or ours) with negative emotions that will impact your progress.
sum += (rms.analyze() - sum) * smoothingFactor;
float rms_scaled = sum * (height/2) * 5;
This is smoothing your peak amplitude over time and you are NOT using rms_scaled any where in the code.
You could use this to move a straight line up and down in place of the ellipse in the example.
If you want to smooth the data in waveform.data you should do it in the loop on that data.
I was able to adapt the smoothing code to do this in the loop on the waveform.data and then plot smoothed_data vs x.
