LTXVAudioVAELoader - ComfyUI Built-in Node Documentation - ComfyUI

The LTXV Audio VAE Loader node loads a pre-trained Audio Variational Autoencoder (VAE) model from a checkpoint file. It reads the specified checkpoint, loads its weights and metadata, and prepares the model for use in audio generation or processing workflows within ComfyUI.

Inputs

Parameter	Description	Data Type	Required	Range
`ckpt_name`	Audio VAE checkpoint to load. This is a dropdown list populated with all the files found in your ComfyUI `checkpoints` directory.	COMBO	Yes	All files in the `checkpoints` folder. The list is generated at runtime.

The selected file must be a valid LTXV audio VAE checkpoint. The node keeps only the audio VAE and vocoder weights from the file and raises an error if the loaded model is not a valid VAE.

Outputs

Output Name	Description	Data Type
`Audio VAE`	The loaded Audio Variational Autoencoder model, ready to be connected to other audio processing nodes.	VAE
