Minim AudioPlayer length Description Returns the length of the sound in milliseconds. If for any reason the length could not be determined, this will return -1. However, an unknown length should not impact playback. Signature ```int length() ``` Returns int: the length of the sound in milliseconds Related AudioPlayer Example ```/** * This sketch demonstrates how to use the cue method of AudioPlayer. * When you cue, it is always measured from the beginning of the recording. * So cue(100) will set the "playhead" at 100 milliseconds from the beginning * no matter where it currently is. Cueing an AudioPlayer will not change the playstate, * meaning that if it was already playing it will continue playing from the cue point, * but if it was not playing, cueing will not start playback, it will simply set the point * at which playback will begin. If an error occurs while trying to cue, the position will not change. * If you try to cue to a negative position or try to cue past the end of the * recording, the amount will be clamped to zero or length(). * * Click in the window to cue to that position in the file. */ import ddf.minim.*; Minim minim; AudioPlayer groove; void setup() { size(512, 200, P3D); minim = new Minim(this); groove = minim.loadFile("groove.mp3"); groove.loop(); } void draw() { background(0); stroke( 255 ); for(int i = 0; i < groove.bufferSize() - 1; i++) { line(i, 50 + groove.left.get(i)*50, i+1, 50 + groove.left.get(i+1)*50); line(i, 150 + groove.right.get(i)*50, i+1, 150 + groove.right.get(i+1)*50); } stroke( 255, 0, 0 ); float position = map( groove.position(), 0, groove.length(), 0, width ); line( position, 0, position, height ); text("Click anywhere to jump to a position in the song.", 10, 20); } void mousePressed() { // choose a position to cue to based on where the user clicked. // the length() method returns the length of recording in milliseconds. int position = int( map( mouseX, 0, width, 0, groove.length() ) ); groove.cue( position ); }``` Usage Web & Application
