ComfyUI Extension: ComfyUI · Egregora Audio Super‑Resolution

ComfyUI-Egregora-Audio-Super-Resolution Introduction

Welcome to the ComfyUI-Egregora-Audio-Super-Resolution extension! This powerful tool is designed to enhance your audio files by bringing them up to studio-grade sample rates directly within ComfyUI. Whether you're working with music or other audio content, this extension provides a seamless way to upscale and enhance your audio, making it sound clearer and more professional. It includes three main upscaling and enhancement nodes, along with a suite of integrated utility tools for denoising, upscaling, and evaluating audio quality. This means you can improve your audio without needing to create complex workflows, making it an ideal solution for AI artists looking to enhance their audio projects effortlessly.

How ComfyUI-Egregora-Audio-Super-Resolution Works

At its core, the ComfyUI-Egregora-Audio-Super-Resolution extension uses advanced algorithms to improve the quality of audio files. Think of it like a magnifying glass for sound—just as a magnifying glass can reveal details in a picture, this extension reveals the finer details in your audio. It does this through a process called "audio super-resolution," which involves increasing the sample rate of your audio files. This is akin to increasing the resolution of an image, allowing for more detail and clarity. The extension also includes tools for denoising and dereverberation, which help to clean up the audio by removing unwanted noise and echoes, much like how a photo editor can remove blemishes from a picture.

ComfyUI-Egregora-Audio-Super-Resolution Features

The extension offers a variety of features to enhance your audio:

• Audio Super Resolution (FlashSR): This feature uses a one-step diffusion upsampler to increase the sample rate of your audio, making it sound more detailed and vibrant. It's particularly music-friendly, ensuring that your tracks maintain their original quality while being enhanced.
• **Spectral Enhance (Fat Llama
• GPU/CPU):** This feature provides iterative spectral enhancement, which refines the audio's frequency spectrum. It can be run on both GPU and CPU, making it versatile and accessible regardless of your hardware setup.
• Integrated Utility Toolsets: These include tools for denoising (using RNNoise and DeepFilterNet), dereverberation (using WPE), and audio codec encoding/decoding (using DAC). Additionally, the Eval Pack offers tools for preparing and judging audio clips, measuring loudness, and more.

Each feature can be customized to suit your needs. For example, you can adjust the overlap seconds in the Audio Super Resolution feature to eliminate any ticks between audio chunks, or tweak the threshold value in the Spectral Enhance feature to achieve the desired level of enhancement.

ComfyUI-Egregora-Audio-Super-Resolution Models

The extension includes different models tailored for specific tasks:

• FlashSR Model: Ideal for upscaling audio to higher sample rates, this model is perfect for music and other high-quality audio content.
• Fat Llama Model (GPU/CPU): This model is used for spectral enhancement and can be run on either GPU or CPU, depending on your system's capabilities.

These models can be selected based on the specific requirements of your project, allowing you to choose the best tool for the job.

What's New with ComfyUI-Egregora-Audio-Super-Resolution

The extension is regularly updated to improve its features and performance. Recent updates include:

• v0.2.0: Introduction of the Enhance, Eval, and Null toolsets, along with a new installer and warmup processes to ensure smoother operation.
• v0.1.0: The initial release, featuring the FlashSR super-resolution node and the Fat Llama spectral enhancement nodes for both GPU and CPU.

These updates enhance the extension's capabilities, making it more efficient and user-friendly for AI artists.

Troubleshooting ComfyUI-Egregora-Audio-Super-Resolution

Here are some common issues you might encounter and how to resolve them:

• FlashSR Import Error: If you encounter an import error, try deleting the deps/FlashSR_Inference/ directory and restarting ComfyUI to re-bootstrap the extension.
• Missing FlashSR Weights: Ensure that the required weight files are placed in the models/audio/flashsr/ directory, or set the EGREGORA_FLASHSR_HF_REPO environment variable to point to a repository containing these files.
• CUDA/CuPy NVRTC Errors (Windows): If you experience errors related to CUDA or CuPy, install the necessary NVIDIA runtime wheels and ensure your CuPy installation matches your CUDA version.
• FFmpeg Not Found: Make sure FFmpeg is installed and added to your system's PATH to enable audio reading and encoding.
