Converting FLV to MP3 If you plan to convert the FLV to an audio only file format, I recommend using WinFF. The software is free and reasonably easy to use. The process is a simple three steps: 1) After downloading and installing WinFF, launch the application and select the FLV file or files you want to convert to MP3. 2) Choose the MP3 (audio only) option from the Choose Format to Convert to… menu. 3) Pick a Destination folder to save your file(s) and click Start Converting. The default settings for MP3 output from WinFF is 64kbps 22050Hz audio, which is acceptable for voice audio. Import the finished MP3 into your iTunes Library when you’re done and put it on your iPod.
