EmptyAceStep1.5LatentAudio - ComfyUI Built-in Node Documentation

Complete documentation for the EmptyAceStep1.5LatentAudio node in ComfyUI. Learn its inputs, outputs, parameters and usage.

The Empty Ace Step 1.5 Latent Audio node creates an empty latent tensor designed for audio processing. It generates a silent audio latent of a specified duration and batch size, which can be used as a starting point for audio generation workflows in ComfyUI. The node calculates the latent length based on the input seconds and a fixed sample rate.

Inputs

Parameter	Description	Data Type	Required	Range
seconds	The duration of the audio to generate, in seconds (default: 120.0).	FLOAT	Yes	1.0 - 1000.0
batch_size	The number of latent images in the batch (default: 1).	INT	Yes	1 - 4096

Outputs

Output Name	Description	Data Type
LATENT	An empty latent tensor representing silent audio, with a type identifier of “audio”. The output also includes a downscale_ratio_temporal value of 1764, which is used for temporal downscaling in audio processing.	LATENT
