   hi Wendy,
   see the my code of converting mp3 convertor

   Hi,
   Please check the below code..

   import ws.schild.jave.*;

   import java.io.File;

   public class AudioConverter {
   public static void main(String[] args) {
   File source = new File("input.wav");
   File target = new File("output.mp3");

       // Set audio attributes for MP3
       AudioAttributes audio = new AudioAttributes();
       audio.setCodec("libmp3lame");
       audio.setBitRate(128000);
       audio.setChannels(2);
       audio.setSamplingRate(44100);
   
       EncodingAttributes attrs = new EncodingAttributes();
       attrs.setFormat("mp3");
       attrs.setAudioAttributes(audio);
   
       // Encode
       Encoder encoder = new Encoder();
   
       try {
           encoder.encode(source, target, attrs);
           System.out.println("Conversion completed!");
       } catch (EncoderException e) {
           e.printStackTrace();
       }
   }
   

   }

   check the maven dependancy..
