An accessible music visualizer
Every control is reachable from the keyboard, state changes are announced to screen readers, motion follows your system preference and a flash guard limits strobing. None of it is a paid tier, because there is no paid tier.
Who this is for
- People who navigate by keyboard or with a screen reader
- Anyone who needs reduced motion or less flashing
- Teachers and venues with an obligation to accommodate
Operable from the keyboard
H hides and shows the interface, Space plays and pauses, the arrow keys change scene, 1–9 jump straight to one, M turns on the microphone, K starts the keyboard instrument and ? opens the shortcut list. The controls are ordinary focusable elements with visible focus rings, not canvas-only hotspots.
Announced, not only drawn
A polite live region announces state changes — audio loaded, scene changed, recording started — so a screen-reader user knows what happened without seeing the canvas. The free-play panel announces the current octave and input state the same way, and the on-screen keys are real buttons with labels.
Motion and flashing under your control
Reduced motion starts from your operating system’s setting and softens beat shake, zoom pump and hype surges. Flash guard caps large brightness swings. Both are single toggles in Tune → Studio, and both apply to exports as well as to the screen.
How to do it
- Open BLOOB and press ? for the shortcut list
- Use H to hide or show the controls, Space to play, ← → to change scene, 1–9 to jump
- Open Tune → Studio and set Reduced motion and Flash guard as you need them
- Press M for the microphone, or K to play the keyboard instrument
Questions people ask about accessible music visualizer
Is it formally WCAG compliant?
It has not been audited. Keyboard operation, visible focus, live-region announcements, reduced motion and a flash limiter are implemented; if something is unreachable for you, report it with the speech-bubble button in the app and it gets fixed.
Does the picture have to be seen to be useful?
Not only. It is often used the other way around — as a way to see music. There is a separate guide for deaf and hard-of-hearing listeners.
Does it work with a screen magnifier?
Yes. The interface scales with browser zoom and becomes a bottom sheet on narrow screens.
Is any accessibility feature behind a paywall?
No. There is no paid tier at all, and there will not be one.
