Audio Reactivity Settings

Refer to Audio Reactivity Settings for in-depth information about the user interface.

First Steps: Getting Started with Audio Reactivity

Attach the microphone to the Lightform device

• LF2+ has a built-in microphone on top of the device, so there's no need for an external USB microphone.
  • You can use an external USB microphone if you prefer. When using an external USB microphone, the built-in microphone is disabled.
• LF2 requires an external USB microphone.
  • An external USB microphone is not provided with the LF2.
• LFC Kit uses the included camera's built-in microphone.

Tested and supported USB microphones

• Samson Go Mic
• Logitech BRIO
• Sound Adapter / Dongle
• You may try to use an untested USB microphone. Lightform technical support is unable to provide help or recommendations with untested microphones.

For some other options, here are some microphones that customers have confirmed work with their devices, but are not officially supported or tested by Lightform: 

• USB Conference Mic
• Blue Yeti USB Mics

Next Steps: Publish a project and calibrate the microphone

Publish a project

If you haven't done so already, publish a project to the Lightform device. Your project must contain some visual content. All content types (Effects, videos, and images) can react to audio.

Calibrate the microphone

Your microphone must be calibrated to your surroundings in order for audio reactivity to work properly. First, turn off all the audio in your environment. This includes music playing from your sound system and all other sound sources. Then:

1. Click Audio Reactivity on the Control Page.
2. Enable the Enabled switch if it isn't already enabled.
3. Click the Calibrate Sound Levels button and wait a few seconds. While the calibration is in progress, sound bars will be displayed with a red background on top of your projected project.
4. Your microphone is now calibrated!

Test the microphone

To quickly test your microphone, after following the above calibration steps, enable the Show Test Sound Bars switch. Sound bars will appear on top of your projected project. Snap your fingers, speak, or play music on your sound system. The sound bars will animate as audio is processed.

• Increase the Gain Intensity setting.
• Perform the calibration steps one more time.

Finally: Adjusting Audio Reactivity

Apply Audio Reactive filters

1. Click Audio Reactivity on the Control Page.
2. Enable the Enabled switch if it isn't already enabled.
3. If this is your first time using audio reactivity, click the Reset Settings button, to ensure all settings are in a predictable state.
4. Enable at least one filter by checking the appropriate Filters checkboxes. For example, check Wiggle.
5. Adjust Gain Intensity as desired.
6. If this is your first time using audio reactivity, you should increase the Gain Intensity.

Other Tasks: Maintaining Your Audio Reactive Project

You can return to the Lightform Creator control page at any time to modify the audio reactivity settings of the published project on your Lightform device. You will want to do this when:

• You want different audio reactivity behavior - Modify the various Audio Reactivity settings.
• Your Lightform device has been moved or the audio environment has changed - Click the Calibrate Sound Levels button.

Common Questions

• Does my LFC Kit / LF2 have sound reactivity?
• Does LF2 support sound reactivity?
• I already have an LFC Kit, how do I get sound reactivity?
• Can I play sound from the LF2 to be reactive?
• Why can't I hear my video's sound from my device?
• What microphone do I need to use for sound reactivity with my device? 
• If I import my own media (images and video)- will they react to sound?
• Is the internet required for sound reactivity to work on my published project?
• Does the audio reactivity require a computer at the scene?
