🎙️ Microphone Audio Driver

Version: 0.1.3 Author: F1dg3t

📌 Description

The Microphone Audio Driver addon allows you to drive any rig property (such as bone rotation, shape key values, or custom properties) in real-time using microphone input.

Perfect for:

• Reactive animations
• Voice-driven facial rigs
• Audio-visual performances
• Real-time feedback in scenes

⚙️ How to Use

1. Access the Addon Panel

• In the 3D Viewport, open the Sidebar (N key)
• Switch to the MAD tab

2. Configure Your Setup

• Microphone: Select your microphone (e.g., BlueSnoball, MicrophoneArray, etc.)
• Target Object: Use the eyedropper to choose the object with the driven property
• Data Path: Enter the property path, such as:

pose.bones["funny_hinge"].rotation_euler[0]

• Volume Scale: Multiply the volume sensitivity
• Default Value: Baseline value when there's no sound
• Update Interval: Refresh rate in seconds (e.g. 0.05 for 20 FPS updates)

3. Start Audio Driver

• Click Start Audio Driver to begin updating the property in real-time
• Watch your rig respond to your voice or environment

4. Stop Audio Driver

• Click Stop Audio Driver to release the microphone and stop updates

🛠️ Troubleshooting

• If nothing responds, check your microphone device is correctly selected.
• Make sure the data path is correct and the property is keyable. (Full data path is not required)
• Blender restricts some updates from threads — this addon safely queues UI updates via the main thread loop.

💻 MacOS Builds

• MacOS has been showing issues with platform specific sounddevice wheels, so a separate version can be found on GitHub Releases.
