**scikit-maad** is an open source Python package dedicated to the quantitative analysis of environmental audio recordings. This package was designed to
1. load and process digital audio,
2. segment and find regions of interest,
3. compute acoustic features, and
4. estimate sound pressure level.
This workflow opens the possibility to scan large audio datasets and use powerful machine learning techniques, allowing to measure acoustic properties and identify key patterns in all kinds of soundscapes.

## Operating Systems
`scikit-maad` seamlessly supports Linux, macOS, and Windows operating systems.
## Interpreter
`scikit-maad` requires one of these interpreters:
- Python >= 3.8 < 3.11
## Packages dependency
`scikit-maad` requires these Python packages to run:
- matplotlib >=3.6
- numpy >= 1.21
- pandas >= 1.5
- resampy >= 0.4
- scikit-image >= 0.19
- scipy >= 1.8
## Installing from PyPI
`scikit-maad` is hosted on PyPI. The easiest way to install the package is using `pip` the standard package installer for Python:
```bash
$ pip install scikit-maad
```
## Quick start
The package is imported as `maad`. To use scikit-maad tools, audio must be loaded as a numpy array. The function `maad.sound.load` is a simple and effective way to load audio from disk. For example, download the [spinetail audio example](https://raw.githubusercontent.com/scikit-maad/scikit-maad/production/data/spinetail.wav) to your working directory. You can load it and then apply any analysis to find regions of interest or characterize your audio signals:
```python
from maad import sound, rois
s, fs = sound.load('spinetail.wav')
rois.find_rois_cwt(s, fs, flims=(4500,8000), tlen=2, th=0, display=True)
```
## For advance users
### Installing from source
If you are interested in developing new features for `scikit-maad` or working with the latest version, clone and install it:
```bash
$ git clone https://github.com/scikit-maad/scikit-maad.git
$ cd scikit-maad
$ pip install --editable .
```
### Running tests
Install the test requirements:
```bash
$ pip install pytest
```
And run the tests:
```bash
$ cd scikit-maad
$ pytest
```

## About the project
In 2018, we began to translate a set of audio processing functions from Matlab to an open-source programming language, namely, Python. These functions provided the necessary tools to replicate the Multiresolution Analysis of Acoustic Diversity (MAAD), a method to estimate animal acoustic diversity using unsupervised learning (Ulloa et al., 2018). We soon realized that Python provided a suitable environment to extend these core functions and to develop a flexible toolbox for our research. During the past few years, we added over 50 acoustic indices, plus a module to estimate the sound pressure level of audio events. Furthermore, we updated, organized, and fully documented the code to make this development accessible to a much wider audience. This work was initiated by [Juan Sebastian Ulloa](https://www.researchgate.net/profile/Juan_Ulloa), supervised by Jérôme Sueur and Thierry Aubin at the [Muséum National d'Histoire Naturelle](http://isyeb.mnhn.fr/fr) and the [Université Paris Saclay](http://neuro-psi.cnrs.fr/) respectively. Python functions have been added by [Sylvain Haupert](https://www.researchgate.net/profile/Sylvain_Haupert), [Juan Felipe Latorre](https://www.researchgate.net/profile/Juan_Latorre_Gil) ([Universidad Nacional de Colombia](https://unal.edu.co/)) and Juan Sebastián Ulloa ([Instituto de Investigación de Recursos Biológicos Alexander von Humboldt](http://www.humboldt.org.co/)).
