The LTXV Empty Latent Audio node creates a batch of empty (zero-filled) latent audio tensors. It uses the configuration from a provided Audio VAE model to determine the correct dimensions for the latent space, such as the number of channels and frequency bins. This empty latent serves as a starting point for audio generation or manipulation workflows within ComfyUI.

Inputs

Parameter	Data Type	Required	Range	Description
frames_number	INT	Yes	1 to 1000	Number of frames. The default value is 97.
frame_rate	INT	Yes	1 to 1000	Number of frames per second. The default value is 25.
batch_size	INT	Yes	1 to 4096	The number of latent audio samples in the batch. The default value is 1.
audio_vae	VAE	Yes	N/A	The Audio VAE model to get configuration from. This parameter is required.

Note: The audio_vae input is mandatory. The node will raise an error if it is not provided.

Outputs

Output Name	Data Type	Description
Latent	LATENT	An empty latent audio tensor with the structure (samples, sample_rate, type) configured to match the input Audio VAE.
