# helia_edge.layers.preprocessing.spec_augment

Signal-only spectrogram masking using the shared augmentation contract.

## helia_edge.layers.preprocessing.spec_augment.SpecAugment2D

`class` · `python`

```python
SpecAugment2D(
    freq_mask_param: int,
    time_mask_param: int,
    n_freq_mask: int = 1,
    n_time_mask: int = 1,
    mask_value: float = 0.0,
    **kwargs={},
)
```

Mask frequency (height) and time (width), independently per example.
