**完美解决个人微信音频amr文件与mp3格式互转**  
**1、安装gcc ffmpeg**  
wget http://downloads.sourceforge.net/lame/lame-3.100.tar.gz  
tar -zxvf lame-3.100.tar.gz  
cd lame-3.100  
./configure --prefix=/usr/local  
make && make install  
ln -s /usr/local/lib/libmp3lame.so.0.0.0 /usr/lib64/libmp3lame.so.0  
wget http://ffmpeg.org/releases/ffmpeg-3.4.1.tar.bz2  
tar -jxvf ffmpeg-3.4.1.tar.bz2  
cd ffmpeg-3.4.1  
./configure --prefix=/usr/local --pkg-config-flags=--static --enable-libmp3lame --disable-x86asm  
make && make install  
  
**2、安装/silk-v3-decoder**  
cd /usr/local/soft  
wget https://github.com/kn007/silk-v3-decoder/archive/master.zip  
unzip master.zip  
chmod -R +x /usr/local/soft/silk-v3-decoder-master/  
silk-v3-decoder/converter.sh 微信amr文章文件路径名 mp3  
  
**3、改造一个encoder脚本，decoder已经有了不用改造了**  
converter-encoder.sh(请拷贝以下脚本放到silk-v3-decoder-master目录下)

\# Link: https://github.com/kn007/silk-v3-encoder  
\# Usage: sh converter.sh silk\_v3\_file/input\_folder output\_format/output\_folder flag(format)  
\# Flag: not define ---- not define, convert a file

**4、用java调用脚本**  
private static String silkv3Path="/usr/local/soft/silk-v3-decoder-master/";  
  
/\*\*  
\* 将amr转成mp3，参考http://www.wityx.com/post/824\_1\_1.html  
\* @param coderPath  
\* @param amrfilePath  
\*/  
public static void converterDecoderMp3(String coderPath, String amrfilePath) \{  
if(StringUtils.isBlank(coderPath))\{  
coderPath = silkv3Path;  
\}  
String decoderCmd = coderPath + "converter.sh " + amrfilePath;  
exeCmd(decoderCmd);  
\}

\* 将mp3转成amr，参考http://www.wityx.com/post/824\_1\_1.html

\*/  
public static void converterEncoderAmr(String coderPath, String mp3filePath) \{  
if(StringUtils.isBlank(coderPath))\{  
coderPath = silkv3Path;  
\}  
String encoderCmd= coderPath + "converter-encoder.sh " + mp3filePath;  
exeCmd(encoderCmd);  
\}  
  
private static void exeCmd(String commandStr) \{  
BufferedReader br = null;  
try \{  
Process p = Runtime.getRuntime().exec(commandStr);  
br = new BufferedReader(new InputStreamReader(p.getInputStream()));  
String line = null;  
StringBuilder sb = new StringBuilder();  
while ((line = br.readLine()) != null) \{  
sb.append(line + "\\n");  
\}  
System.out.println(sb.toString());  
\} catch (Exception e) \{

\} finally \{  
if (br != null) \{
