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

ParameterDescriptionData TypeRequiredRange
secondsThe duration of the audio to generate, in seconds (default: 120.0).FLOATYes1.0 - 1000.0
batch_sizeThe number of latent images in the batch (default: 1).INTYes1 - 4096

Outputs

Output NameDescriptionData Type
LATENTAn 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
