It sounds backwards, but audio to FLV is a real need: plenty of platforms and tools only accept video, so Flippy re-packs your audio audio inside an FLV wrapper. Where FLV accepts your audio's codec the sound crosses over untouched; where it doesn't, it's re-encoded once. The FLV that comes out is built for nothing new: today it's mostly old downloads waiting to be rescued.
A classic audio to FLV job: voice memos, downloads and session exports, bound for the odd legacy pipeline that still demands Flash video.
Whatever the recording, audio just wants to be heard: the trick is picking a shape that plays where you need it. It comes from wherever your camera, screen recorder or download made it.
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 audio 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.
Settings for audio to FLV: none to pick. Where the FLV container accepts your audio's audio codec, the stream is copied bit for bit; where it doesn't, Flippy re-encodes it once and leaves the levels alone.
| audio | FLV | |
|---|---|---|
| Born | wherever your microphone, DAW or download came from | 2002, Macromedia (later Adobe), for Flash Player |
| Type | audio · any format | video · container |
| Best for | any sound file: music, voice memos, podcasts, session exports | nothing new: today it's mostly old downloads waiting to be rescued |
| Weak spot | nothing in particular; the limits belong to whichever format it happens to be wearing | playing anywhere at all since Flash was switched off in 2020 |
| Typical size | anywhere from tiny voice notes to studio-sized masters | for video content, small files with dial-up-era expectations about quality; wrapping audio alone stays about the size of the audio |
| Plays on | Depends entirely on the format it lands in. | 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 audio behind: FLV simply opens in more of the places that matter.
Seconds for most audio files: there are no pictures to encode, so wrapping the audio as FLV is nearly as fast as copying it. Both files auto-delete within an hour.
