Audio visualizer

Make a music visualizer video in four steps

1. Choose an audio file (MP3, WAV, M4A, FLAC, OGG, or the soundtrack of a video), or load the short original sample song.
2. Pick a style, a shape (16:9 for YouTube, 9:16 for Shorts, Reels and TikTok, 1:1 for a square post), colors and a background. Add a title and artwork if you like.
3. Press play to watch the live preview. Set a start and end time to export only part of the track.
4. Press Export video. A progress bar shows how far the render is, and you can cancel at any time. Download the MP4 when it is done.

How the visualizer turns sound into pictures

For every frame of the video, the tool looks at a short window of the audio around that moment (2,048 samples, about 46 milliseconds) and measures how much energy sits in 64 frequency bands spaced like musical octaves, from the low bass at 40 Hz up to 16 kHz. Each band is scaled against the loudest moments of your own track, so a quiet acoustic song moves as much as a loud electronic one. Bars rise instantly when a note hits and fall back over about a tenth of a second, which keeps the motion readable instead of flickering. The oscilloscope style draws the actual sound wave of that moment, and the particle style speeds its particles up with the bass, so kick drums push them outwards.

Exported frame by frame, not screen-recorded

Many browser visualizers record the screen while the song plays, so the export takes as long as the song and drops frames whenever the computer is busy. This one renders each frame offline with an exact timestamp and passes it to the video encoder built into your browser (WebCodecs), together with the original audio. The result is a smooth 30 or 60 fps video whose picture matches the sound exactly, and on most computers it finishes faster than the song plays. The live preview uses the same drawing code, so what you see while it plays is what you get.

Formats, sizes and speed

The tool exports an MP4 with H.264 video and AAC audio when your browser can encode them, which is what YouTube, Instagram, TikTok and most editors expect. Where a browser cannot encode H.264 (some Linux builds of Chromium, for example) it exports a WebM with VP9 or VP8 video and Opus audio instead, and says so. Landscape videos are 1920 × 1080, vertical ones 1080 × 1920 and square ones 1080 × 1080, or 720p if you need a faster export. In our test on an Apple M2 laptop in Chromium, 30 seconds of 1080p video at 30 fps took about 7 seconds, at 60 fps about 13 seconds, and at 720p about 4 seconds. A phone takes longer and may need 720p for long songs. One video can be up to 10 minutes long, because the finished file is held in memory before you download it.

Your music stays on your device

The song is decoded, analysed and encoded inside this browser tab. It is not uploaded, and AudioClover never receives the audio, the artwork or the file name. Check that you have the rights to the music and any image before you post the video: a visualizer does not change who owns the song, and platforms may still match it with Content ID.
