One handy utility that everyone needs nowadays is a software program that can extract audio, sound, or background music from home movies, YouTube videos, or any other video file. In this article, I'm going to give step-by-step instructions on how to use a program called Eahoosoft Audio Converter. Using this nifty little application, you can extract audio from AVI, MPEG, MPG, FLV, DAT, WMV, MOV, MP4, and 3GP and save them into MP3 format or WAV and AC3 format also!
Now, we take extract mp3 from flv video files for example!

Select Audio supported AAC, AC3,MP3, WAV as the output file format for the selected files from the open "Profile" drop-down list
Step 3. Set audio parameters
You can see Audio parameters contain sample rate, channels, encoder, and bitrate.
Step 4. click "Convert" button to start conversion
