Complex Audio Fade

Complex Audio Fade is a beginner-friendly audio transition system designed for VRChat worlds using UdonSharp. It allows audio to smoothly fade in when the local player enters an area and fade back out when they leave.

Instead of music or ambient sounds suddenly starting and stopping, Complex Audio Fade creates clean and professional transitions between different sections of your world.

What It Does

When the local player enters a trigger zone, the assigned AudioSource begins playing and gradually fades up to the selected target volume.

When the player leaves the trigger zone, the audio smoothly fades back down. Once the volume reaches zero, the AudioSource automatically stops playing.

The system runs locally, meaning every player experiences their own independent audio transitions. One player entering or leaving an area will not affect another player's audio.

Possible Uses

Complex Audio Fade can be used for:

• Entering or exiting rooms
• Background music zones
• Ambient environmental audio
• Horror and Backrooms worlds
• Liminal spaces
• Indoor and outdoor transitions
• Tunnels and underground areas
• Secret rooms
• Event areas
• Shops, lounges, clubs, and apartments
• Storytelling areas
• Different sections of larger worlds

The system is useful anywhere audio needs to smoothly appear or disappear based on the player's location.

Easy to Set Up

Complex Audio Fade is designed so beginners can use it with ease. No programming knowledge is required for normal setup.

Simply:

1. Add the Complex Audio Fade component to a GameObject.
2. Assign the AudioSource you want it to control.
3. Add or assign a collider configured as a trigger.
4. Adjust the target volume and fade settings in the Inspector.

Once configured, the system automatically handles audio playback, fading, and stopping.

All supported customization is completed through the Unity Inspector. Buyers do not need to edit the included source code.
