# AbsCosWave 📅🅕🅝
## Documentation
- Class name: `AbsCosWave`
- Category: `FizzNodes 📅🅕🅝/WaveNodes`
- Output node: `False`

The AbsCosWave node generates a wave pattern based on the absolute value of a cosine function, modulated by parameters such as phase, amplitude, x_translation, and max_value. It's designed to create dynamic, visually interesting waveforms for various applications.
## Input types
### Required
- **`phase`**
    - The phase parameter controls the periodicity of the wave, affecting how frequently the wave pattern repeats over a given interval.
    - Comfy dtype: `FLOAT`
    - Python dtype: `float`
- **`amplitude`**
    - Amplitude determines the height of the wave peaks, influencing the overall intensity of the wave pattern.
    - Comfy dtype: `FLOAT`
    - Python dtype: `float`
- **`x_translation`**
    - X_translation shifts the wave pattern along the horizontal axis, allowing for adjustments in the wave's starting position.
    - Comfy dtype: `FLOAT`
    - Python dtype: `float`
- **`max_value`**
    - Max_value sets the upper limit for the wave's value, capping the peak height and affecting the wave's amplitude.
    - Comfy dtype: `FLOAT`
    - Python dtype: `float`
- **`current_frame`**
    - Current_frame represents a specific point in time or sequence, used to calculate the wave's position and shape at that moment.
    - Comfy dtype: `INT`
    - Python dtype: `int`
## Output types
- **`float`**
    - Comfy dtype: `FLOAT`
    - The first element of the output tuple, representing the calculated wave value in its precise form.
    - Python dtype: `float`
- **`int`**
    - Comfy dtype: `INT`
    - The second element of the output tuple, providing an integer approximation of the wave's current state.
    - Python dtype: `int`
## Usage tips
- Infra type: `CPU`
- Common nodes: unknown
