Audio Waveform Video Generator
Upload an audio clip, pick a waveform style and background, and download an MP4 with an animated waveform synced to the sound - great for sharing a podcast clip, voice note or song snippet on social media.

Preguntas frecuentes
How long can the audio clip be?
Only the first 20 seconds of the audio are used for the video. This keeps the number of rendered frames - and your browser's memory use - reasonable, since every frame is drawn and encoded locally on your device.
What video sizes are supported?
Square (1:1), good for feed posts, and vertical (9:16), good for Stories and Reels. Both export at 720px on the shorter side.
Can I use my own background image?
Yes, upload an image and it will be used behind the waveform (cropped to fill the frame) instead of a flat color.
Is this processed on a server?
No, the whole thing runs in your browser: the Web Audio API reads the waveform data, a canvas draws each animation frame, and the same ffmpeg.wasm engine used by the Video to GIF tool encodes the frames and audio into an MP4. Nothing is uploaded anywhere.
