I use ffmpeg to transcode. To install ffmpeg, I used install_ffmpeg_ubuntu.sh from foreign brother icaliman. He also provided install_ffmpeg_centos.sh. If you cannot access it, please go through the wall. Oh, I mainly use AMR -> WAV (because Matlab can only process speech in wav format, and my homework happened to require Matlab, so I fell into the trap of ffmpeg).
