### Audioperm
A python library for generating different permutations of audible segments from audio files. 

```console
pip install audioperm
```

#### Use:

* Silence Removal from Audio
* Audio / Speech augmentation
* Word segmentation
* Word level permutation generation
* Add new synthetic data for deep learning
* Speaker recognition, Speaker verification, Audio classification, Audio fingerprinting

#### Word segmentation

```python
from audioperm import AudioPerm
from audioperm.utils import save_audio

ap = AudioPerm("i_love_cats.m4a")
label = "i love cats"

words = ap.word_segments()
label_words = label.split()

for i, w in enumerate(words):
  save_audio(w, label_words[i] + ".wav")
```

```
cats.wav  i_love_cats.m4a  i.wav  love.wav
```

#### Word-level permutation

```python
import numpy as np
from audioperm import AudioPerm
from audioperm.utils import save_audio

ap = AudioPerm("i_love_cats.m4a")
ap.word_segments(return_words=False)
perm_sentences = ap.permute(n_permutations = 5)

for i, s in enumerate(perm_sentences):
  save_audio(s, f"perm_{i}.wav")
```

```
cats.wav	   i.wav       perm_1.wav    perm_4.wav
i_love_cats.m4a    love.wav    perm_2.wav    perm_0.wav  
perm_3.wav
```

#### `permutations` on multiple files

```python
from audioperm import read_audio, word_segments, permutations

ap = read_audio(["bangla_demo.wav", "i_love_cats.m4a"])
out = word_segments(ap)
perms = permutations(out, n_permutations = 5)
```

#### Fixed-length segments

* Generate fixed length audible segments (with permutation/augmentation)

```python
from audioperm import fixed_len_segments
fixed_len_segments("bangla_demo.wav", return_segments = False, save_path = "fls_out", save = True, segment_size = 0.5)
out = fixed_len_segments("bangla_demo.wav", return_segments = True, max_segments = 5, permute = True, save = False, segment_size = 0.5)
```
