What fast FLV-to-MP3 converter can you recommend?

I have Windows and I use Ffmpeg. This Windows video converter like all the above converters supports many video formats, AVI, MP4, iPod, PSP, 3GP (mobile phones), iPhone, WMV, ASF, MOV, QuickTime, MPEG, MPG2 etc. It lets you convert videos to your TV, website, mobile phone, iPod, iPhone, PSP, MP4 player and more with optimized presets. Also you can extract beautiful music from movies.

I use online tools for this purpose. I can share this article www.videoconverter.com/how-to-convert-flv-to-mp3.html how to convert FLV files to MP3 in three different ways – with SuperSpeed Video Converter, with freeware, or via an online conversion tool. I think it will help you.
