Extract audio from YouTube video, Round 2

Almost everytime when I was invited to play drum set at Sunday service, the worship leader would send out the corresponding YouTube links for the songs that we were going to play, so that we could get used to the arrangement.  This is particular important to me as a drummer.  Unlike other parts that has score or tabs written on paper , I didn't have any drum score, so I relied on what I heard from the audio of the YouTube videos.

Up until now I was using Firefox and Downloadhelper to download those YouTube video into flv files, and then extract out the audio part (usually in mp3 format) using FLVExtract.  That workflow needs to be changed as I just found out that the video downloaded by Downloadhelper are all mp4 instead of Flv.

NO problem though, as I found need tool to deal with the problem.  There's a open source freeware called Yamb that act as the extraction front end, and then there is MP4Box as the extraction engine.  Once I set everything up, I can extract the aac files from the video, and continue listen to the audio part while I am driving.  Problem once again solved.
