Fixed sinusoidal signal addition.

## helia_edge.layers.preprocessing.sine_wave.AddSineWave

`class` · `python`

```python
AddSineWave(
    sample_rate: float = 1,
    frequency: float = 100,
    amplitude: float = 0.1,
    data_format: str | None = None,
    **kwargs={},
)
```

Add a fixed sine wave in training and inference.
