Spatial Audio Mixing: A Practical Guide

Understanding Spatial Audio

Spatial audio places sound in a 3D environment, letting listeners perceive direction and distance. Formats like Dolby Atmos and Apple Spatial Audio each have distinct workflows.

Core Concepts

• Object-based mixing: Place sounds as objects in 3D space
• Bed channels: Traditional channel foundation (7.1.2 typical)
• Metadata: Position, size, and divergence per object

DAW Setup

Use Dolby Atmos Renderer or Logic Pro built-in Atmos tools. Route stems to object tracks and position them using the panner plugin.

Speaker Layout

Minimum recommended: 7.1.4. For professional work, 9.1.6 provides smoother overhead panning.

Mixing Tips

Keep dialogue anchored to center. Use height channels for ambience. Avoid placing critical elements directly overhead.
