Schedule Smoothing

Documentation

• Class name: SaltScheduleSmoothing
• Category: SALT/AudioViz/Scheduling/Filter
• Output node: False

Provides a method to smooth a given schedule list by applying a smoothing factor to each element, effectively filtering out rapid changes and creating a more gradual transition between values.

Input types

Required

• schedule_list
  • The list of schedule values to be smoothed. This list represents a sequence of numerical values that will undergo smoothing to reduce abrupt changes.
  • Comfy dtype: LIST
  • Python dtype: List[float]
• smoothing_factor
  • A factor determining the degree of smoothing applied to the schedule list. A higher value results in a smoother transition between schedule values.
  • Comfy dtype: FLOAT
  • Python dtype: float

Output types

• schedule_list
  • Comfy dtype: LIST
  • The smoothed list of schedule values, where each value has been adjusted according to the smoothing factor to create a gradual transition.
  • Python dtype: List[float]

Usage tips

• Infra type: CPU
• Common nodes: unknown
