In this article we will look at a very easy way (in terms of software required) of extracting sound from a flash file (.flv). Please note that it might be done quickly, by using a sound converting software, but in case you only have the latest free version of 7-Zip, and just do not have anything better to do, try this out!

As we know, an FLV file is a container-format, which means the system inside it is similar to the one we use in archives, so the media files are converted into an archive. Therefore, you might want to open the file using a zipping software (I recommend 7-Zip), and explore the FLV file. There you will find two files (video’s name is myvideo), myvideo.video.flv and myvideo.audio.flv. Extract the audio file, and inside, you will find myvideo.audio.mp3!
