This asset ships with complete audio functionality.

As the river is generated the spline’s slope and the amount of turbulence (Geometry section: displacement) is anaylized.

• If a section has some turbulence it is considered Rapids
• If a section is a slope is it a Cascade
• Otherwise it is a Stream

In the project you’ll find a default Audio Profile that defines the sound clips and properties for these 3 types.

You can of course use your own audio clips here. Or use a different profile for different rivers.

River Audio Manager

This component is required, as it handles the runtime pooling of Audio Source components.

Create one through GameObject->Audio->River Audio Manager

At runtime it:

• Polls all active river segments
• Checks if the Audio Listener is entering or leaving its audible range
• Assigns Audio Source component to it, and sets up the appropriate audio clips
• Or releases Audio Source component used by it back to the pool

In play mode you’ll see the audible segments draw as yellow surfaces.
