Which Visualizer Style Should You Use?

How Does an Audio Visualizer Work?

An audio visualizer measures how loud each pitch in the music is, many times a second, and turns those measurements into shapes. This one takes a slice of your song 30 times a second and splits it into frequency bands, from deep bass to sparkly highs, using a maths trick called a Fourier transform.

• Bars and mirror: each bar is one band, so the kick drum moves the bars on the left and cymbals move the ones on the right.
• Circle: the same bands wrapped around your cover art, with the circle swelling on every kick.
• Wave: no bands at all, just the shape of the sound wave itself, like an old oscilloscope.

The preview and the download use exactly the same maths, so what you see while it plays is what you get. When you export, your browser draws every frame and encodes the video itself, which is why your song never has to be uploaded anywhere.

What Size Should a Visualizer Video Be?

HD looks sharper on big screens. 720p makes smaller files, exports faster and uses less memory, so it's the better pick on a phone and plenty for TikTok and Reels.

Is This Audio Visualizer Really Free?

Yes: no sign-up, no watermark, no limit on how many videos you make. It costs nothing to run because your own browser does the work. Comparing options?
