Java程序将amr格式音频转成mp3格式

相信很多人都遇到amr格式的音频文件不能直接在网页播放的问题，有人使用QuickTime插件的辅助，以下介绍如何使用jave.jar包将amr格式的音频文件转成mp3格式，官方下载地址http://www.sauronsoftware.it/projects/jave/download.php，闲话少说，直接上例子

package com.nnbrightstar.lbtm.common.utils;

import it.sauronsoftware.jave.AudioAttributes;
import it.sauronsoftware.jave.Encoder;
import it.sauronsoftware.jave.EncoderException;
import it.sauronsoftware.jave.EncodingAttributes;
import it.sauronsoftware.jave.InputFormatException;
import java.io.File;

public class ChangeAudioFormat {
	public static void main(String[] args) throws Exception {
		String path1 = "E:\\Eclipse_Web\\lbtm\\webapp\\uploadFiles\\1395047224460.amr";
		String path2 = "E:\\Eclipse_Web\\lbtm\\webapp\\uploadFiles\\1395047224460.mp3";
		changeToMp3(path1, path2);
	}

	public static void changeToMp3(String sourcePath, String targetPath) {
		File source = new File(sourcePath);
		File target = new File(targetPath);
		AudioAttributes audio = new AudioAttributes();
		Encoder encoder = new Encoder();

		audio.setCodec("libmp3lame");
		EncodingAttributes attrs = new EncodingAttributes();
		attrs.setFormat("mp3");
		attrs.setAudioAttributes(audio);

		try {
			encoder.encode(source, target, attrs);
		} catch (IllegalArgumentException e) {
			e.printStackTrace();
		} catch (InputFormatException e) {
			e.printStackTrace();
		} catch (EncoderException e) {
			e.printStackTrace();
		}
	}
}
