The clip is listed on a user-generated soundboard under the name Helo, with K. Steinbach credited in the title, but no wider source work, show or release is attached to it in the available information. That makes it best understood as a small online audio clip rather than a line from a known film, series or game. Its appeal comes from the same place as many short greeting sounds: it is instantly recognisable as a hello, easy to drop into an edit, and short enough to repeat without losing its timing.
