Convert FLV to WAV.
Pull the soundtrack out of an old Flash Video file as uncompressed WAV for editing or archiving.
Archive the sound properly
If an old FLV holds a recording you want to keep, a WAV of the soundtrack opens in any editor today and in the years to come.
Edit without another loss
Decoding once to WAV means later edits and exports do not add another round of compression.
Size change
WAV is uncompressed, about 10 MB a minute for stereo.

Extracting WAV from FLV
This pulls the audio track out of your FLV and encodes it as WAV; the video is discarded. WAV is lossless, so the audio is kept faithfully.

Common questions
Is it free?+
Yes. Convert FLV to WAV free. No signup and no watermark. Free covers 10 server conversions a day, up to 100 MB a file. Pro removes the daily limit and raises the file limit to 2 GB.
Is my file private?+
Your file is uploaded to a private bucket, converted on our own engine, and auto-deleted after 1 hour. It is never sent to a third-party converter.
Will it sound better than the FLV?+
No. FLV soundtracks are usually MP3 or AAC. The WAV keeps exactly what they decode to, with no further loss, but cannot restore detail.
Is the video kept?+
No. Only the audio goes into the WAV. To keep the picture, use FLV to MP4.
