How to Convert FLV to WAV

Upload a FLV file
Step 1

Add an FLV video with audio

Choose one local FLV file in the online converter, or add your FLV files in UniConverter Desktop. The source must contain an audio track to produce useful WAV audio.

Choose WAV as the output format
Step 2

Select WAV for the audio output

Choose WAV if it appears in the online output list. In UniConverter Desktop, select WAV and review the available output settings; confirm a PCM option there if your editing workflow requires it.

Download the converted WAV file
Step 3

Convert and save the audio

Start the online conversion and download the WAV file, or convert your local files in UniConverter Desktop and save the results. The WAV contains audio, not the FLV video picture.

FAQs About Converting FLV to WAV

Add an FLV file that contains audio, select WAV if available, convert, and save the audio-only result. For editing that requires PCM WAV, check the current Desktop output settings for a PCM option.
No, converting to WAV cannot restore detail already lost in the FLV source audio. The result is limited by the source track and the export settings used.
The online converter offers a free, no-signup entry point for a quick one-off conversion. Confirm that FLV input and WAV output are listed in the current browser workflow before starting.
Yes, UniConverter Desktop supports batch conversion for multiple files. Treat the online converter as a one-off workflow, not a batch tool.
Choose WAV when you need an audio-only file for editing; choose a video output such as MP4 when you need to keep the picture. WAV extraction does not preserve the FLV video track.
