Black Kite Particle with Bird Call (VRChat)

Overview

This is a black kite (tonbi) particle asset with call sounds.
It is recommended for adding a subtle accent to natural sky environments.

The distinctive “pi-hyororo” call sound was recorded on location at Kikuna coast in japan and is based on real field recordings.
This asset is designed for VRChat worlds.

Features

• By default, around 10 black kites fly across the sky.
• Call sounds play at random intervals between 20 and 60 seconds, selected from two different call variations.
• The playback interval can be adjusted via Udon properties.
• Sounds are played as 3D audio from the approximate position of each black kite and move and rotate along with their flight paths.
