The EmptyLatentAudio node creates an empty latent tensor for audio processing. It generates a blank audio latent representation with a specified duration and batch size, which can be used as a starting point for audio generation or processing workflows. The node automatically calculates the appropriate latent dimensions based on the audio duration and sample rate.

Inputs

ParameterDescriptionData TypeRequiredRange
secondsThe duration of the audio in seconds (default: 47.6)FLOATYes1.0 - 1000.0
batch_sizeThe number of latent images in the batch (default: 1)INTYes1 - 4096

Outputs

Output NameDescriptionData Type
LATENTReturns an empty latent tensor for audio processing with the specified duration and batch size. The tensor has a shape of [batch_size, 64, length], where length is calculated from the audio duration and sample rate. The output also includes metadata indicating the type is “audio” and a temporal downscale ratio of 2048.LATENT
