Flippy turns WAV into FLV for free: upload the WAV above and download it wrapped as FLV, sound untouched.
It sounds backwards, but WAV to FLV is a real need: plenty of platforms and tools only accept video, so Flippy re-packs your WAV audio inside an FLV wrapper. Nothing is re-recorded: the sound in your WAV crosses over untouched, and the FLV that comes out is built for nothing new: today it's mostly old downloads waiting to be rescued.
WAV is audio with nothing taken away: every sample intact, every megabyte accounted for. It was born in 1991, Microsoft and IBM, and its real weak spot is being carried around: it refuses to shrink.
FLV is a relic of the Flash era: the format YouTube grew up on, stranded when Flash died. The Flash Video container, typically holding old H.263, VP6 or early H.264 streams. That makes it the right destination when what you need is nothing new: today it's mostly old downloads waiting to be rescued.
Drop your WAV file into the flipper above, or click to browse for it.
Check the output format: FLV is already selected for you.
Hit Convert, give it a moment, then download your new FLV.
| WAV | FLV | |
|---|---|---|
| Born | 1991, Microsoft and IBM | 2002, Macromedia (later Adobe), for Flash Player |
| Type | audio · uncompressed | video · container |
| Best for | recording, editing and mastering, where every last bit matters | nothing new: today it's mostly old downloads waiting to be rescued |
| Weak spot | being carried around: it refuses to shrink | playing anywhere at all since Flash was switched off in 2020 |
| Typical size | about 10 MB per minute at CD quality: ten times the size of an MP3 | small files with dial-up-era expectations about quality |
| Plays on | Universal on desktops and pro audio gear; clumsy on the mobile web. | Almost nothing modern; VLC and converters are its retirement home. |
No. Wrapping audio in an FLV container doesn't touch the sound itself: it's the same stream in a different box.
About the same, plus a sliver of container overhead. The audio stream is unchanged; FLV just adds a video-shaped envelope.
Almost nothing modern; VLC and converters are its retirement home. That's the usual reason people leave WAV behind: FLV simply opens in more of the places that matter.
It scales with length and resolution: short clips finish in seconds, long HD videos can take a few minutes. Files auto-delete within an hour after.
