I had a Java based app. that used Java Sound to tap into the sound flowing through the system to make a trace of it. It worked well on my own (Windows based) machine, but failed completely on some others. It was determined that in order to get it working on those machines, would take … Read more
I prefer this way in Java 8: CountDownLatch syncLatch = new CountDownLatch(1); try (AudioInputStream stream = AudioSystem.getAudioInputStream(inStream)) { Clip clip = AudioSystem.getClip(); // Listener which allow method return once sound is completed clip.addLineListener(e -> { if (e.getType() == LineEvent.Type.STOP) { syncLatch.countDown(); } }); clip.open(stream); clip.start(); } syncLatch.await();
If you’re using the Java Sound API, you can set the volume with the MASTER_GAIN control. import javax.sound.sampled.*; AudioInputStream audioInputStream = AudioSystem.getAudioInputStream( new File(“some_file.wav”)); Clip clip = AudioSystem.getClip(); clip.open(audioInputStream); FloatControl gainControl = (FloatControl) clip.getControl(FloatControl.Type.MASTER_GAIN); gainControl.setValue(-10.0f); // Reduce volume by 10 decibels. clip.start();
Well, the simplest answer is that at the moment Java can’t produce sample data for the programmer. This quote is from the official tutorial: There are two ways to apply signal processing: You can use any processing supported by the mixer or its component lines, by querying for Control objects and then setting the controls … Read more
Here is the barebones code: import java.io.File; import java.io.IOException; import java.io.SequenceInputStream; import javax.sound.sampled.AudioFileFormat; import javax.sound.sampled.AudioInputStream; import javax.sound.sampled.AudioSystem; public class WavAppender { public static void main(String[] args) { String wavFile1 = “D:\\wav1.wav”; String wavFile2 = “D:\\wav2.wav”; try { AudioInputStream clip1 = AudioSystem.getAudioInputStream(new File(wavFile1)); AudioInputStream clip2 = AudioSystem.getAudioInputStream(new File(wavFile2)); AudioInputStream appendedFiles = new AudioInputStream( new SequenceInputStream(clip1, clip2), … Read more
How can I detect silence when recording operation is started in Java? Calculate the dB or RMS value for a group of sound frames and decide at what level it is considered to be ‘silence’. What is PCM data? Data that is in Pulse-code modulation format. How can I calculate PCM data in Java? I … Read more
As mentioned, Java Sound does not support MP3 by default. For the types it does support in any specific JRE, check AudioSystem.getAudioFileTypes(). One way to add support for reading MP3 is to add the JMF based mp3plugin.jar1 to the application’s run-time class-path. That link is known to be less than entirely reliable. The Jar is … Read more
