Audio Repeat

Documentation

  • Class name: SaltAudioRepeat
  • Category: SALT/AudioViz/Audio/Process
  • Output node: False

The SaltAudioRepeat node is designed for repeating an audio segment a specified number of times. It enables the creation of looped audio effects by duplicating the input audio according to the user-defined repetition count.

Input types

Required

  • audio
    • The 'audio' parameter is the raw audio data to be looped. It is essential for determining the base audio content that will be repeated.
    • Comfy dtype: AUDIO
    • Python dtype: bytes
  • repeat_times
    • The 'repeat_times' parameter specifies how many times the audio should be looped. It directly influences the length and content of the output audio.
    • Comfy dtype: INT
    • Python dtype: int

Output types

  • audio
    • Comfy dtype: AUDIO
    • The output is the looped audio, which is the result of repeating the input audio segment for the specified number of times.
    • Python dtype: bytes

Usage tips

  • Infra type: CPU
  • Common nodes: unknown
