Welcome to Geiss HDR, a music visualizer.

Select your audio source:

(easiest) <-- start here
(easy) ...or line input
(medium)
(hard) ...or window, or screen

Tips:

- To play your own mp3 files or folders, just drag and drop them onto this window.

- Don't try to use 'microphone' for music coming from this device; it won't pick up the music well, since microphones are placed to minimize feedback.

- To capture the audio from a browser tab or window, or your whole screen, on Mac OS, you might need to (just once) go to System Settings -> Privacy & Security -> Screen & System Audio Recording, then under 'System Audio Recording Only', enable it for 'Google Chrome'. If 'Google Chrome' does not show in the list, click the + symbol and add 'Google Chrome.app', then enable it.
