GetAudioLatentSize - ComfyUI Built-in Node Documentation

Reads an audio latent and returns its length, audio channel count, and batch size, so those values can be reused without decoding the audio.

Reads an audio latent and returns its length, audio channel count, and batch size, so those values can be reused without decoding the audio. Use it to size noise masks or match audio and video lengths before sampling. The measured values are also printed on the node itself.

Inputs

Parameter	Description	Data Type	Required	Range
latent	The audio or audio/video latent to inspect. When the latent holds several streams, the audio stream is measured.	LATENT	Yes	-

Outputs

Output Name	Description	Data Type
length	The length of the audio latent, in latent cells rather than audio samples.	INT
audio_channels	The number of audio channels. Latents without an audio channel dimension report one channel.	INT
batch_size	The number of latents in the batch.	INT
