ComfyUI-AudioScheduler Introduction
ComfyUI-AudioScheduler is an extension designed to help AI artists integrate audio data into their creative projects. This extension provides a set of tools (nodes) that allow you to load audio files, analyze their properties, and use this information to control various aspects of your AI-generated animations or visualizations. By leveraging audio data, you can create more dynamic and synchronized multimedia experiences.
Key Features:
- Loading Audio Files: Supports MP3 and WAV formats.
- Amplitude Analysis: Reads and visualizes the amplitude of audio over time.
- Frequency Analysis: Performs Fast Fourier Transforms (FFTs) to analyze frequency components.
- Graphical Visualization: Generates graphs to preview amplitude and frequency data.
- Dynamic Text Prompts: Creates text prompts driven by audio amplitude changes.
How ComfyUI-AudioScheduler Works
ComfyUI-AudioScheduler works by breaking down audio files into their fundamental components and using this data to influence other media elements. Here’s a simplified explanation:
- Loading Audio: The extension can load audio files in MP3 or WAV formats.
- Analyzing Audio: It reads the amplitude (volume) and frequency (pitch) information from the audio.
- Visualizing Data: The extension can create visual graphs of the amplitude and frequency data.
- Controlling Media: This data can then be used to control animations, generate text prompts, or influence other visual elements in your project.
Imagine you have a piece of music and you want certain visual effects to sync with the beats or melody. ComfyUI-AudioScheduler can analyze the music and provide the necessary data to make this synchronization possible.

Frequently Asked Questions
- Q: Can I use other audio formats?
- A: Currently, only MP3 and WAV formats are supported.
- Q: How do I adjust the frequency range for analysis?
- A: Use the
lower_band_range
and upper_band_range
parameters in the relevant nodes.
- Q: What does normalizing amplitude do?
- A: Normalizing scales the amplitude data to a standard range, making it easier to compare and use in visualizations.
