![]() After that, we get the Scanner object and take input from the user if the input is equal to stop, then we call the mp3Player.close() that calls the close() method of the Player class, and it stops the music. Now in the main() method, we initialize filename with the MP3 filename and then create an object of the MP3Player class with the filename passed in its constructor. ![]() To start the thread, we call the start() function of the thread. In the run() method, we call the play() function that comes with the Player class of the library. We do not want to block the main thread, so we create a new Thread() and call the run() method inside it. One thing to note is that the thread in which the audio is playing that thread gets blocked until the audio processing is completed. Byte Stream: FileInputStream, FileOutputStream Now we pass the bufferedInputStream object to the constructor of the Player class that returns an object. Since you just want to play the sound, you can use example I provide below: Look at the file:C:/image/song.wav, there is a file: keyword before your the directory declaration. We make a play() method that takes the mp3FileToPlay and pass it to the constructor of FileInputStream that converts the file to an InputStream and then we pass this InputStream object to BufferedInputStream that converts it into a BufferedInputStream. Then we generate a constructor of the class MP3Player and take the mp3FileToPlay String as a parameter and initialize the class variable. Play an MP3 File Using JLayerīelow, we create a class called MP3Player and two variables in which the first is the String that will hold the name and path of the MP3 file to play, and the second variable is the object jlPlayer of the class Player. The native libraries of Java do not allow us to play audio that is in MP3 format thus here we use two external libraries that demand minimal setup. Today we will have a look at the ways to play MP3 in Java. ejre1.7.0_04/bin/java -classpath jl1.0.1.jar javazoom.jl.converter.jlc Gill\ Scott-Heron-\ The\ Revolution\ Will\ Not\ Be\ Televised.mp3 -p out.wavįileName = Gill Scott-Heron- The Revolution Will Not Be Televised.Created: September-06, 2021 | Updated: October-17, 2021 Managed to decode a mp3 in less time than the runtime using Java SE Embedded 6 rm out.wav time. Takes 3 times more to decode than the runtime of the song. Time java -cacao -classpath jl1.0.1.jar javazoom.jl.converter.jlc file.mp3 -p out.wav I did some tests with JLayer1.0.1 on my RPI and it is slow: Afterwards copy the undecode file to another machine and see if the wav is ok. Should be a Sound Event defined in sounds.json (for example, entity. In Java Edition, must be a resource location. Should be a sound event defined in sounddefinitions.json (for example, ). Tip: Use the controls property to display audio controls (like play, pause, seeking, volume, etc, attached on the audio). In Bedrock Edition, it must be either a single word (no spaces) or a quoted string. Tip: This method is often used together with the pause () method. If it is less that the total runtime of the song you are in business. The play () method starts playing the current audio. So unless that decoder is seriously flawed it should work.Ĭan you do the full decode to a file? If yes measure the time it takes. So I'll post here:ġ-"Not enough CPU"- I used to do mp3 decoding by software in a Sparc Station with a 35MHz CPU. I do not have enough score to make comments. Java AudioInputStream The complete Java sound file application If you'd like the complete source code for this Java 'play sound file' application, along with the Ant build script that is used to build the application on a Mac OS X system, it's available here as my free, complete Java Mac (Swing) application.
