Place it just before a reply, comment or reveal appears, then follow it with Pop Sound Effect once the new item is on screen. Use it once per scene, early in the edit, and save a second alert for the next arrival so each one keeps its impact.
关于此声音
This is a short notification chime, just under two seconds long, built around a bright electronic tone that rises and settles quickly. It gives a light, reassuring feeling, like a friendly tap on the shoulder that says something new has arrived without startling you. It works as a clear signal for a message, email or alert, cutting through speech while staying gentle enough for repeated use.
