How the studio works

The microphone measures sound volume and frequency; it does not recognize words or draw named objects. Sound creates moving, mirrored ink trails. Drag anywhere to make and smear marks. Tap the bell or play music without a microphone.

Microphone access needs an HTTPS page or localhost and your browser's permission. Some embedded HTML runners block it. Open the page directly if that happens. Audio and drawings stay in this page; nothing is uploaded.

Undo restores the last touch stroke or approximately two seconds of sound painting. Saving makes a PNG with paper behind the ink. Fresh paper clears the canvas.
