Through the following code I can play and cut and audio file.
Is there any other way to avoid using a shutdown hook?
The problem is that whenever I push the cut button , the file doesn't get saved until I close the application
thanks
......................
void play_cut() {
try {
// First, we get the format of the input file
final AudioFileFormat.Type fileType = AudioSystem.getAudioFileFormat(inputAudio).getType();
// Then, we get a clip for playing the audio.
c = AudioSystem.getClip();
// We get a stream for playing the input file.
AudioInputStream ais = AudioSystem.getAudioInputStream(inputAudio);
// We use the clip to open (but not start) the input stream
c.open(ais);
// We get the format of the audio codec (not the file format we got above)
final AudioFormat audioFormat = ais.getFormat();
// We add a shutdown hook, an anonymous inner class.
Runtime.getRuntime().addShutdownHook(new Thread()
{
public void run()
{
// We're now in the hook, which means the program is shutting down.
// You would need to use better exception handling in a production application.
try
{
// Stop the audio clip.
c.stop();
// Create a new input stream, with the duration set to the frame count we reached. Note that we use the previously determined audio format
AudioInputStream startStream = new AudioInputStream(new FileInputStream(inputAudio), audioFormat, c.getLongFramePosition());
// Write it out to the output file, using the same file type.
AudioSystem.write(startStream, fileType, outputAudio);
}
catch(IOException e)
{
e.printStackTrace();
}
}
});
// After setting up the hook, we start the clip.
c.start();
} catch (UnsupportedAudioFileException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (LineUnavailableException e) {
e.printStackTrace();
}
}// end play_cut
