Place this clip after a close-up of a trade menu or an item offer on screen, before your reply line. Follow it with a vine boom sound for a rejected deal, or a bell ding sound effect when the trade finally succeeds.
About this sound
This short clip is the Minecraft villager voice, a brief nasal hum lasting just over half a second. It feels deadpan and mildly unimpressed, like a merchant weighing up a trade without saying a word. The sound comes from Minecraft, where villagers make this noise while wandering and trading with players.
