Place it as the base layer under the whole edit, then add a Classic Error Sound when a window fails and a Discord Notification when a message pops up, so the desktop moments land on top of the background.
このサウンドについて
This clip is a Windows background sound, an ambient bed drawn from the familiar computer setting its name points to. It works as a steady backdrop rather than a moment on its own, filling space without pulling focus. It feels calm and slightly nostalgic, like a quiet desk setup with a system running nearby, easing a scene rather than interrupting it.
