The clip runs for about 15 seconds, giving you enough repeated beeping to use as ambience or trim into a shorter reaction cue. Download the MP3 once to keep it available offline, then select a compact section if your phone allows custom ringtones or notification tones. Its sharp upper frequencies can compete with speech, so lower the file when placing it beneath dialogue. For a more exaggerated mistake sequence, follow the final beep with a censor beep or an error sound rather than stacking every effect at once.
