Rendering with a triangle waveform
This class shows how a simple score can be rendered as an audio file using a triangle waveform.
To hear the result download the MP3 file below.
WaveformExample3.mp3 [104K]
Lets have a closer look.
import jm.music.data.*; import jm.JMC; import jm.audio.*; import jm.util.*; // this class introduces triangle wave public class WaveformExample3 implements JMC { public static void main(String[] args) { new WaveformExample3(); } public WaveformExample3() { // make a jmusic score Phrase melody = new Phrase(); for(int i = 0; i < 24; i++) { Note n = new Note((int)(Math.random() * 12) * 2 + 60, QUAVER); melody.addNote(n); } Score score = new Score(new Part(melody)); // set up audio instrument Instrument wave = new TriangleInst(44100); // for jMusic 1.1 or earlier put the instrument in an array // Instrument[] ensemble = {wave}; // render audio file of the score Write.au(score, "WaveformExample3.au", wave); // for jMusic 1.1 or earlier substitute the line above with // Write.au(score, "WaveformExample.au", ensemble); } } |
