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) 


 #!/bin/bash 

 # File: converter.sh 

 # Date: August 19th, 2016 

 # Time: 18:56:52 +0800 

 # Author: http://www.wityx.com/post/824_1_1.html 

 # Blog: https://kn007.net 

 # 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 

 # other value ---- format, convert a folder, batch conversion support 

 # Requirement: gcc ffmpeg 


 # Colors 

 RED="$(tput setaf 1 2>/dev/null || echo '\e[0;31m')" 

 GREEN="$(tput setaf 2 2>/dev/null || echo '\e[0;32m')" 

 YELLOW="$(tput setaf 3 2>/dev/null || echo '\e[0;33m')" 

 WHITE="$(tput setaf 7 2>/dev/null || echo '\e[0;37m')" 

 RESET="$(tput sgr 0 2>/dev/null || echo '\e[0m')" 


 # Main 

 cur_dir=$(cd `dirname $0`; pwd) 


 if [ ! -r "$cur_dir/silk/encoder" ]; then 

 echo -e "${WHITE}[Notice]${RESET} Silk v3 Encoder is not found, compile it." 

 cd $cur_dir/silk 

 make && make encoder 

 [ ! -r "$cur_dir/silk/encoder" ]&&echo -e "${RED}[Error]${RESET} Silk v3 Encoder Compile False, Please Check Your System For GCC."&&exit 

 echo -e "${WHITE}========= Silk v3 Encoder Compile Finish =========${RESET}" 

 fi 


 cd $cur_dir 


 while [ $3 ]; do 

 [[ ! -z "$(pidof ffmpeg)" ]]&&echo -e "${RED}[Error]${RESET} ffmpeg is occupied by another application, please check it."&&exit 

 [ ! -d "$1" ]&&echo -e "${RED}[Error]${RESET} Input folder not found, please check it."&&exit 

 TOTAL=$(ls $1|wc -l) 

 [ ! -d "$2" ]&&mkdir "$2"&&echo -e "${WHITE}[Notice]${RESET} Output folder not found, create it." 

 [ ! -d "$2" ]&&echo -e "${RED}[Error]${RESET} Output folder could not be created, please check it."&&exit 

 CURRENT=0 

 echo -e "${WHITE}========= Batch Conversion Start ==========${RESET}" 

 ls $1 | while read line; do 

 let CURRENT+=1 

 ffmpeg -i "$1/$line" -f s16le -ar 24000 -ac 1 -acodec pcm_s16le "$2/$line.pcm" > /dev/null 2>&1  

 $cur_dir/silk/encoder "$2/$line.pcm" "$2/${line%.*}.$3" -tencent > /dev/null 2>&1 

 rm "$2/$line.pcm" 

 [ ! -f "$2/${line%.*}.$3" ]&&echo -e "[$CURRENT/$TOTAL]${YELLOW}[Warning]${RESET} Convert $line false, maybe ffmpeg no format handler for $3."&&continue 

 echo -e "[$CURRENT/$TOTAL]${GREEN}[OK]${RESET} Convert $line To ${line%.*}.$3 Finish." 

 done 

 echo -e "${WHITE}========= Batch Conversion Finish =========${RESET}" 

 exit 

 done 


 ffmpeg -i "$1" -f s16le -ar 24000 -ac 1 -acodec pcm_s16le "$1.pcm" > /dev/null 2>&1  

 $cur_dir/silk/encoder "$1.pcm" "${1%.*}.amr" -tencent > /dev/null 2>&1 

 rm "$1.pcm" 

 [ ! -f "${1%.*}.amr" ]&&echo -e "${YELLOW}[Warning]${RESET} Convert $1 false, maybe ffmpeg no format handler for amr."&&exit 

 echo -e "${GREEN}[OK]${RESET} Convert $1 To ${1%.*}.amr Finish." 

 exit

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 

 * @param coderPath 

 * @param mp3filePath 

 */ 

 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) { 

 e.printStackTrace(); 

 } finally { 

 if (br != null) { 

 try { 

 br.close(); 

 } catch (Exception e) { 

 e.printStackTrace(); 

 } 

 } 

 } 

 } 

 public static void main(String[] args) { 

 String amrfilePath = "/home/1.amr"; 

 String mp3filePath = "/home/3.mp3"; 

 String coderPath = silkv3Path; 

 converterDecoderMp3(coderPath, mp3filePath); 

 converterEncoderAmr(coderPath, amrfilePath); 

 }
