FLV (Flash Video) is primarily a video file format developed by Adobe Systems. While it can contain audio, it is not exclusively an audio file format. However, if you need to convert FLV files to WAV format, you can easily do so using an online FLV to WAV converter. These online tools allow you to extract the audio component from FLV files and convert it into the WAV format, which is suitable for various audio editing or playback purposes.
