The methods I discussed to download the audio from YouTube in Mp3 format does not apply to all the other video content hosting sites and portals out there. So what you can do is to download the video in FLV format from them and then extract the audio from it in Mp3 format.
Xed FLV Sound Extractor is a free portable tool that converts the FLV video into Mp3 audio file quickly. The whole extraction is fast and efficient.
Just load the FLV video and hit Extract. It will ask for the destination where you want to save the output file, select any and click Save.
Once the extraction is complete, it will automatically open the folder contain the output Mp3 audio file.
