Open your own browser-supported audio or start with the built-in pulse. Use Play, Pause, the timeline, ten-second seek controls, Loop, Mute, Volume, Orbit, Bars, Trace, and Fullscreen. Space toggles track playback, arrow keys seek, and M mutes. Your selected sound remains local to this browser session. Manual scrolling releases the guided ride without stopping the narration; choose Rejoin whenever you want the page to follow the voice again.
