ComfyUI-TangoFlux

ComfyUI Custom Nodes for "TangoFlux: Super Fast and Faithful Text to Audio Generation with Flow Matching". These nodes, adapted from the official implementations, generates high-quality 44.1kHz audio up to 30 seconds using just a text promptproduction.

Installation

1. Navigate to your ComfyUI's custom_nodes directory:

cd ComfyUI/custom_nodes

2. Clone this repository:

git clone https://github.com/LucipherDev/ComfyUI-TangoFlux

3. Install requirements:

cd ComfyUI-TangoFlux
python install.py

Or Install via ComfyUI Manager

Check out some demos from the official demo page

Example Workflow

Usage

Models can be downloaded using the install.py script

Manual Download:

• Download TangoFlux from here into models/tangoflux
• Download text encoders from here into models/text_encoders/google-flan-t5-large

(Include Everything as shown in the screenshot above. Do Not Rename Anything)

The nodes can be found in "TangoFlux" category as TangoFluxLoader, TangoFluxSampler, TangoFluxVAEDecodeAndPlay.

If you are on low VRAM, try enabling offload_model_to_cpu in TangoFluxSampler.

The audio output of the TangoFluxVAEDecodeAndPlay can be used as audio input for theComfyUI-VideoHelperSuite VideoCombine node. (This will not sync audio to the video)

TeaCache can speedup TangoFlux 2x without much audio quality degradation, in a training-free manner.
