I have set up all adaptive bitrate by following this link

Finally , I have to do encode mp3 file with myself and apply to wowza. So I have encode one mp3 file through FFMPEG I used some Linux command for convert mp3 to lower bit-rate for encode manually. And put this files in wowza content folder

ffmpeg -i 54dd82e02a4eefbd0330aa95.mp3 -ab 128k 54dd82e02a4eefbd0330aa9548.mp3

Note For installation ffmpeg in linux found here some link
