Description Returns true if this currently playing.Signature boolean isPlaying() Returns boolean: the current play state Related play ( )pause ( ) FilePlayer Example /** This is an example of how to use a FilePlayer UGen to play an audio file. It support all of the same formats that AudioPlayer does, but allows you to insert the audio from the file into a UGen chain. FilePlayer provides all the same methods that AudioPlayer does for controlling the file playback: play(), loop(), cue(int position), etc. <p> Press any key to pause and unpause playback! <p> For more information about Minim and additional features, visit http://code.compartmental.net/minim/ <p> author: Damien Di Fede */ import ddf.minim.*; import ddf.minim.spi.*; // for AudioRecordingStream import ddf.minim.ugens.*; // declare everything we need to play our file Minim minim; FilePlayer filePlayer; AudioOutput out; // you can use your own file by putting it in the data directory of this sketch // and changing the value assigned to fileName here.
