Frequently asked questions

Why does the browser ask for mic?
Web Audio needs permission to read audio for analysis; we don’t store recordings on our servers.
Echo in the room?
Point the mic away from speakers or lower volume to reduce feedback.
USB mic vs built-in?
USB interfaces usually give cleaner bass and less noise for visualization.
HTTPS requirement?
Most browsers require a secure origin for getUserMedia — use https://beatvisualizer.com or localhost for dev.
