How to Turn Audio Into Video

The Magic of WebAssembly

Usually, when you want to turn audio into video, you have to download bulky desktop software or upload your private audio files to a remote server. We do things differently.

Our tool uses a technology called WebAssembly to run FFmpeg (the industry standard video rendering engine) directly inside your Google Chrome or Safari browser. This means your files never leave your device.

Building the Visuals

Our audio visualization maker doesn't just slap a static image on a video. We use the Web Audio API to pre-analyze your track, mapping the amplitude (volume) to visual effects. When the drop hits in your song, the animated rainbow background pulses and breathes with the music.
