Description
Define the audio input for the analyzer.
Examples
import processing.sound.*; FFT fft; AudioIn in; int bands = 512; float[] spectrum = new float[bands]; void setup() { size(512, 360); background(255); // Create an Input stream which is routed into the Amplitude analyzer fft = new FFT(this, bands); in = new AudioIn(this, 0); // start the Audio Input in.start(); // patch the AudioIn fft.input(in); } void draw() { background(255); fft.analyze(spectrum); for(int i = 0; i < bands; i++){ // The result of the FFT is normalized // draw the line for frequency band i scaling it up by 5 to get more amplitude. line( i, height, i, height - spectrum[i]*height*5 ); } }
