Capture the audio sounds of you knocking on a door, or a table, or some other material. Go for ordinary or go for strange (you know which we like).
If it helps, crank the Rolling Stones Can’t You Hear Me Knocking on your headphones (but no you cannot use that song as a Daily Create, you gotta create it yerself)

Yes. We hear you. Knocking. Who are you?
This might be a good time to try posting your audio files to Soundcloud
This Daily Create has been recycled from previously published ones:
