At about 1.2 seconds, this clip is already compact enough for quick triggers and usually needs no trimming. Download the MP3 to keep it available offline, import it into your preferred soundboard, or assign it as a ringtone or notification tone if your device supports custom audio. Headphones reveal the stereo movement most clearly. When placing it over speech, lower the level enough to preserve the words without hiding the knocks. For a more ordinary alternative, keep a door knocking sound nearby, or pair it with a Discord notification for chat pranks.
