EmptyLatentAudio Description

Generates empty latent audio tensor for audio processing tasks.

EmptyLatentAudio:

The EmptyLatentAudio node is designed to generate an empty latent audio tensor, which can be used as a placeholder or starting point for further audio processing tasks. This node is particularly useful when you need a blank audio canvas to apply various transformations or effects. By providing a specified duration in seconds, the node creates a tensor filled with zeros, representing silence. This can be beneficial for initializing audio data structures in machine learning workflows, ensuring compatibility with models that require specific input dimensions.

EmptyLatentAudio Input Parameters:

seconds

The seconds parameter specifies the duration of the empty latent audio in seconds. This parameter determines the length of the generated audio tensor. The value must be a floating-point number between 1.0 and 1000.0 seconds, with a default value of 47.6 seconds. Adjusting this parameter allows you to control the size of the latent audio tensor, which can be crucial for fitting the requirements of different audio processing tasks.

EmptyLatentAudio Output Parameters:

LATENT

The output of the EmptyLatentAudio node is a dictionary containing a tensor filled with zeros, representing an empty latent audio sample. The dictionary has two keys: samples, which holds the tensor, and type, which is set to "audio". This output can be used as a silent audio base for further processing or as an input to other nodes that require a latent audio format.

EmptyLatentAudio Usage Tips:

Use the seconds parameter to match the duration of the empty latent audio with the requirements of your audio processing pipeline.
Combine this node with other audio transformation nodes to create complex audio effects starting from a silent base.

EmptyLatentAudio Common Errors and Solutions:

Invalid value for `seconds`

Explanation: The value provided for the seconds parameter is outside the allowed range (1.0 to 1000.0).
Solution: Ensure that the seconds parameter is set to a value within the specified range. Adjust the value to be between 1.0 and 1000.0 seconds.

Device not found

Explanation: The node is unable to access the specified device for tensor operations.
Solution: Verify that the device specified in the node's initialization is available and properly configured. Check your system's hardware and software settings to ensure compatibility.
