Description: In this tutorial, we dive into creating an audio spectrum effect in Unreal Engine 5.3 using Niagara. We’ll show how to link audio data with particle systems to make interactive effects based on sound, such as particle movement and size adjustments in response to audio frequencies.

---

Key Points:

• Intro to Audio Spectrum in Niagara: We start with a simple particle effect in Unreal Engine, linked to an audio spectrum. When the audio plays, particle movement is driven by the sound’s frequencies.
• Adjusting for Low Volume Audio: If you work with low-volume sounds, you can adjust parameters to make sure the effect still reacts to the audio. A demonstration shows how different audio types will trigger the effect.
• Creating a Custom Niagara Effect: A custom effect is created using the Taurus shape for particle emission, followed by disabling gravity to control particle behavior. Particle size and other attributes can be easily modified using the audio spectrum.
• Using the Scratch Pad with Audio Spectrum: The audio spectrum is accessed through the scratch pad in Niagara. We link it to particle size adjustments, allowing the size to scale dynamically with audio input.
• Connecting Audio to Particle Size: The tutorial walks you through setting up a float multiplier to modify particle size with audio intensity. This also includes steps on how to integrate this feature with other parameters like rotation.
• Audio-Driven Rotation and Scaling: Using the audio input to manipulate particle rotation and scaling is demonstrated, showing how you can create dynamic, responsive effects that sync with the audio.
• Fine-Tuning the Audio Effect: We explore advanced techniques like adjusting the frequency range, boosting values, and fine-tuning the audio spectrum response for better results.
• Improving Performance: Suggestions for increasing the number of particles and adding curl noise for better visual complexity are made. This also involves controlling particle behavior based on velocity.
• Customizing Audio Effects for Different Sounds: For different types of audio, adjusting the frequency range and intensity of the effect is necessary. We show how to tweak settings for optimal performance with louder beats or quieter sounds.

Additional Notes:

• You can experiment with the settings for different effects, including changing color, size, and velocity based on the audio’s intensity.
• When working with audio of different volumes, remember to adjust the frequency and intensity parameters to keep the effect consistent.
