Place it at the exact beat a message appears on screen, then follow it with the WhatsApp Message Sound Button for the reply and the WhatsApp Bass Boosted Sound Button for a second interruption later in the same scene.
About this sound
This is a short two-and-a-half-second message notification, run through extreme bass boosting so the low end hits hard and the familiar ping feels suddenly enormous. It lands as a jolt, funny and slightly overwhelming, the kind of sound that makes everyone in the room look up at once, and it takes its cue from the standard WhatsApp message alert.
