About Audio to Video
Platforms like YouTube, Instagram and X don't accept plain audio uploads, so this tool wraps your audio in an MP4. Add a JPG, PNG or WebP cover image to show a still picture, or leave it out and get an animated waveform, peak-bar or scrolling-spectrum visual in your chosen color.
When it helps
- Uploading a song, beat or podcast episode to YouTube with its cover art
- Sharing a voice note or audio clip on social media as a video
- Creating a simple visualizer video for a music release
- Posting an audio-only interview where a video file is required
Tips
- With a cover image, the video uses a very low frame rate so the file stays small; the picture is kept up to 1920 pixels wide.
- Without an image, the visual is rendered at 1280 x 720. Waveform suits speech, Peak bars suits beats, and Scrolling spectrum shows frequencies.
- The wave color applies to the waveform and peak-bar styles.
- Long audio with an animated visual takes a while in WebAssembly; files must stay under 2 GB.
