Inhaling whistle that starts at a high pitch, descends, and then ascends to a pitch higher than the start. Recorded on an at2020 condenser microphone with a behringer um2 interface in a homemade recording booth.
A recording that sounds like two people laughing with a rather creepy vibe. They have a slight pitch difference. It's actually a recording of me laughing, doubled and changed pitch.
