What this is
An audio visualizer draws sound as it plays. This one listens to your whole song once before it starts, so every picture is tied to the exact second you hear: the spectrum, the beats, the loudness and how bright the sound is. It has ten modes, eight of them with a page of their own below, and it saves the result as a 1080p or 4K video with your song as the sound track.
How to use it
- Press Play the sample, choose a song of your own, or press Microphone.
- Pick one of the ten modes and one of ten looks, or drag your own colours along the gradient bar; Response sets how hard the picture moves.
- Save a PNG, or press Save video for a 1080p or 4K MP4 with the sound, wide, square or tall for Reels and Shorts, with a title if you want one.
Every mode has its own page:
Words: FFT · spectrum · frequency band
Common questions
Is it free, and is there a watermark?
It is free. Every mode, the microphone, your own songs and PNG pictures need nothing from you. The video is free too, in 1080p or 4K and for the whole song, however long; it asks you to sign in with Google first. There is no watermark on the video or the picture.
Is my song uploaded?
No. The song is read, drawn and turned into video on your own computer. Nothing is uploaded and the sound never leaves your machine; signing in only tells AIKIZI who is saving a video.
How do I save the visualizer as a video?
Press Save video. Pick a shape first if you like (wide 16:9, square, or tall 9:16), 1080p or 4K, and the part of the song with From and To. The page draws every frame at 60 frames a second, adds the song itself as the sound track and your title if you typed one, and saves an MP4 you can post anywhere. It takes about as long as the clip, often less.
Can I make a vertical video for Reels, Shorts or TikTok?
Yes. Under Video choose Tall 9:16 and the picture becomes 1080 × 1920 (2160 × 3840 at 4K); Square 1:1 is there too. Drag From and To to cut a 15 or 30 second clip, add a title, and press Save video. The preview changes shape with you, so what you see is what you get.
Why is the audio visualizer online and not an app?
Because a browser can now do the whole job. The drawing runs on your graphics card through WebGPU (WebGL2 where WebGPU is missing), and the video is encoded by the browser's own encoder, so there is nothing to install and no render queue.
