The SoundTools alternative for when 14 styles run out

Credit where it is due

SoundTools is the cleanest free spectrum visualizer on the web. Open the page, drop a track, pick one of 14 styles, press Export Video, and a 1080p file with the audio baked in lands in your downloads. No account, no watermark, no limit. On the best-free-visualizer page on this site it ranks second, and it earns that.

If a bar chart or a glowing blob over your cover art is the video you want, use it and skip the rest of this page.

Where 14 styles stop

Fourteen styles is a menu, and menus repeat. The circular spectrum, the mirrored bars and the Lava Lamp scene look the same on your channel as on the next one, because the audio only changes a height or a glow. After a few uploads the look is recognisable, and viewers file it under “visualizer” and scroll on.

Groovalizer draws from 2,100+ presets written in the MilkDrop format and rendered by projectM, the open-source successor to Winamp’s visualizer. A preset is a scene in equations: the bass folds the geometry, the treble changes the colour drift, and a feedback loop turns last frame into this one. Two songs through the same preset make two different videos.

Here is the trade. SoundTools gives you a clean video with no strings. Groovalizer gives you a scene, exports it free at 720p with a watermark, and asks $4.99 for a clean copy or $14.99 a month on Pro.

Groovalizer vs SoundTools at a glance

SoundTools facts from soundtools.io/music-visualizer, September 2026. Groovalizer limits come from the plan table the app enforces.

Three things a spectrum tool cannot do

Change per section. Groovalizer’s Song parts give the intro, the drop and the outro a look each, with a soft cut between them. Play live. Live mode takes the microphone and fills a projector at 60 frames per second, cycling presets on a timer, with no account. Be edited. Every preset is a text file you can open in the built-in editor, change while it runs, and save as your own.

SoundTools does one thing well and stops. That is a virtue until you need the second thing.

Which one to open

Open SoundTools for a quick, clean, spectrum-style upload with a zero budget, or when you are on a phone and need a file today. Open Groovalizer when the visuals are part of the music, when the video has to change with the song, or when you want to run it on a wall at a show.

Both keep your audio on your machine. Preview Groovalizer with your own track first; it costs nothing and needs no account.
