Network Bending for ComfyUI

A custom node pack for ComfyUI that enables the creative manipulation of generative models. Allows you to corrupt, modify, and blend neural networks.

Features

• Add Noise: Inject Gaussian noise into model weights
• Scale Weights: Scale model weights up or down to amplify or dampen features
• Prune Weights: Remove small weights for sparsification
• Randomize Weights: Replace portions of weights with random values
• Smooth Weights: Apply spatial smoothing to weight matrices
• Quantize Weights: Reduce weight precision to discrete levels
• Layer Swap: Swap weights between similar layers
• Activation Replace: Replace activation functions
• Weight Transpose: Transpose weight matrices
• Channel Shuffle: Randomly shuffle channels in convolutional layers
• Frequency Filter: Apply frequency domain filtering
• Weight Clustering: Group similar weights together

Mix two models together with various blending modes:

• Linear Interpolation: Simple weighted average of weights
• Weighted Sum: Weighted sum with normalization
• Layer-wise Mix: Different mix ratios for different layers
• Frequency Blend: Mix models in frequency domain
• Random Mix: Randomly select weights from either model

Audio Processing Nodes

The package also includes comprehensive audio processing capabilities for Stable Audio models:

Audio VAE Nodes

• Audio VAE Encode: Encode audio waveforms into latent space
• Audio VAE Decode: Decode latent representations back to audio

Audio Latent Manipulation

• Audio Latent Interpolate: Smoothly interpolate between audio latents
• Audio Latent Blend: Blend multiple audio latents with various modes
• Audio Latent Manipulator: Direct manipulation of audio latent features
• Audio Feature Extractor: Extract specific features from audio latents

Audio Style Transfer

• Audio Style Transfer: Transfer style from one audio to another
• Audio Latent Guidance: Guide generation with reference audio
• Audio Reference Encoder: Encode reference audio for style transfer

Installation

Basic Installation

1. Clone this repository into your ComfyUI custom_nodes directory:

cd ComfyUI/custom_nodes
git clone https://github.com/DavidPiazza/network_bending.git

2. Restart ComfyUI

Audio Network Bending

1. Load an audio model (e.g., Stable Audio VAE)
2. Add audio processing nodes from the network_bending/audio category
3. Connect audio inputs either from file loaders or generated audio
4. Apply bending operations to the audio latents
5. Decode back to audio using Audio VAE Decode

Cross-Modal Bending

Apply image model bending techniques to audio models or vice versa for experimental results.
