SquareWave 📅🅕🅝

Documentation

Class name: SquareWave
Category: FizzNodes 📅🅕🅝/WaveNodes
Output node: False

The SquareWave node generates a square wave pattern based on specified parameters such as phase, amplitude, and translations. It's designed to create distinct, square-shaped oscillations for various applications in signal processing and waveform generation.

Input types

Required

phase
- Defines the period of the square wave. A higher value results in a longer period between wave peaks.
- Comfy dtype: FLOAT
- Python dtype: float
amplitude
- Determines the height of the square wave peaks. A larger amplitude results in taller peaks.
- Comfy dtype: FLOAT
- Python dtype: float
x_translation
- Shifts the wave along the X-axis. This can be used to adjust the starting point of the wave.
- Comfy dtype: FLOAT
- Python dtype: float
y_translation
- Shifts the wave along the Y-axis, adjusting the baseline level of the wave.
- Comfy dtype: FLOAT
- Python dtype: float
current_frame
- Specifies the current frame or point in time for which the wave value is being calculated. This allows for dynamic wave generation over time.
- Comfy dtype: INT
- Python dtype: int

Output types

float
- Comfy dtype: FLOAT
- The primary output of the wave calculation, representing the wave's value at the current frame.
- Python dtype: float
int
- Comfy dtype: INT
- An integer representation of the wave's value at the current frame.
- Python dtype: int
