# augaudio
This package contains multiple simple audio data augmentations in order to increase/test the robustness of neural networks.
###### Original
###### Gaussian Noise
###### Pitch Shift
###### Time Stretch
###### Crush
## Installation
You can install this package via
`pip install augaudio`
## Usage
### Example usage:
```python
import librosa
import augaudio
import soundfile
y, sr = librosa.load('audio.wav')
augmented = augaudio.augment(y, 1, 4)
soundfile.write('augmented.wav', augmented, sr)
```
#### Directly access one of the augmentations:
```python
...
augmented = augaudio.GaussianNoise(y, 4)
...
```
#### Chain augmentations together:
```python
...
augmented = augaudio.GaussianNoise(augaudio.TimeStretch(y, 2), 4)
...
```
#### Iterate over augmentations:
```python
...
for augmentation in range(4):
for intensity in range(1,10):
augmented = augaudio.augment(y, augmentation, intensity)
soundfile.write(str(augmentation) + '-' + str(intensity) + '.wav', augmented, sr)
...
```
### Command Line Usage:
#### Single File:
`augaudio /path/to/audio.wav 0 5`
#### Complete Folder:
`augaudio /path/to/input 0 5 /path/to/output`
## Augmentations
| Augmentation | index | Description | negative intensity |
| --- | --- | --- | --- |
| Augmentations | -2 | Applies /multiple/ random augmentations | available |
| Random | -1 | Applies random augmentation | available |
| GaussianNoise | 0 | Applies gaussian noise to the audio data | n/a |
| PitchShift | 1 | Shifts the pitch of the audio data | available |
| TimeStretch | 2 | Stretches the time of the audio data | n/a |
| Crush | 3 | Crushes details by applying and reversing a pitch shift | available |
