comfyui-dreambait-nodes

A collection of forks, QoL nodes, and utilities for ComfyUI.

Nodes Overview

Aspect Pad Image For Outpainting

A node to calculate arguments for the default ComfyUI node 'Pad Image For Outpainting' based on justifying and expanding to common SDXL and SD1.5 aspect ratios.

Load Media

Loads media from various sources with advanced options for sequence handling.

• Supports images, directories, videos, archives (zip/tar/7z), and URLs.
• Smart sorting options including visual similarity-based ordering.
• Seamless loop creation with loop_first_frame.

Multi Min/Max

A node that finds the minimum or maximum value among multiple inputs. Forked from Impact Pack's MinMax node, extended to support up to 8 inputs. Accepts any comparable type and returns the min/max value of the same type.

String Item Menu

A context selector that extracts an item's index from a list of delimiter-separated strings.

TextPlusPlus

Combines text with optional prepend, append, and override operations.

NumberPlusPlus

A node to perform arithmetic operations on a number, including pre-addition, multiplication, and post-addition. It also provides formatted string outputs for the number, its integer representation, and a boolean indicating if the number is greater than 0.

NumberRemap

A node to remap a number from one range to another.

BoolPlusPlus

A node to handle boolean operations with additional features.

SwitchDuo

A node that switches between two outputs based on a boolean value. Supports overriding the boolean value with an optional input.

ListItemSelector

A node to select an item from a list based on a given index.

ImageFrameBlend

A node to blend frames of an image sequence.

Image Resize Face Aware

A fork of ComfyUI_essentials' Image Resize node with added face detection capabilities:

• All original resize methods (stretch, keep proportion, fill/crop, pad)
• New 'crop to face' method that detects faces, crops to them, and resizes
• New 'crop to face (keep_size)' method that produces a square crop centered on the largest detected face without resizing

Uses OpenCV's DNN face detector for reliable face detection, falling back to center crop if no face is found.

Text Line Select

A node to select specific lines from a text input based on line numbers, with an optional random toggle.

Text Lines To List

Converts multi-line text input into a list, with each line as a separate item.

List Item Extract

Extracts a specific item from a list at the given index, with options for handling out-of-range indices.

MusicGen

A node that generates music using Meta's MusicGen model based on text prompts. This is a fork of comfyui-sound-lab's musicNode, modified to conform to ComfyUI's standard AUDIO format for better integration with the core audio workflow.

Features:

• Text-to-music generation using any MusicGen model:
  • Basic models:
    • small (300M parameters): Fastest, good for testing
    • medium (1.5B parameters): Balanced performance
    • large (3.3B parameters): Highest quality
  • Melody models:
    • melody: Base melody-conditioned generation
    • melody-large: High quality melody-conditioned generation
    • stereo-melody: Stereo melody-conditioned generation
  • Stereo models:
    • stereo-small: Basic stereo generation
    • stereo-medium: Better stereo quality
    • stereo-large: Best stereo quality

Inputs:

• Required:
  • model: Choose from available MusicGen models
  • prompt: Text description of the desired music
  • seconds: Duration of generated audio (1-1000 seconds)
  • guidance_scale: How closely to follow the text prompt (0-20)
  • seed: Random seed for reproducible results
  • device: CPU or auto (uses GPU if available)
• Optional:
  • audio: Input audio for melody-conditioned models (ignored by non-melody models)
  • melody_guidance_scale: Controls how closely melody models follow the input audio

The node outputs audio in the standard ComfyUI AUDIO format, compatible with audio preview and save nodes.

Models are stored in ComfyUI's models directory under 'musicgen/[model_name]' and are downloaded automatically when first selected. You can also manually place model files in these directories if you've downloaded them separately.

Available Nodes

Audio Processing

Normalize Audio

comfy Professional-grade audio normalization using broadcast standards (BS.1770-4) with true-peak limiting.

Inputs:

• audio: AUDIO format input
• target_lufs: Target integrated loudness (default: -14 LUFS for streaming)
• true_peak_limit: Maximum true-peak level (default: -1 dBTP)
• normalize_type: Choose between LUFS or peak normalization

Output:

• Normalized AUDIO

Example usage:

1. Connect your audio source to the NormalizeAudio node
2. Choose normalization type:
   • LUFS: For streaming/broadcast (measures perceived loudness)
   • Peak: For sample libraries or technical applications
3. Set target levels:
   • Streaming: -14 LUFS, -1 dBTP
   • Broadcast: -23 LUFS, -2 dBTP
   • Sample Library: Peak mode, -0.3 dBTP
4. Connect to output nodes

Technical Details:

• Uses BS.1770-4 standard for loudness measurement
• True-peak limiting prevents inter-sample peaks
• LUFS measurement considers perceived loudness
• Handles silence and very quiet audio gracefully
