## Installation


### Using PyPI

The latest stable release is available on PyPI, and you can install it by saying
```
python -m pip install librosa
```

### Using Anaconda

Anaconda users can install using ```conda-forge```:
```
conda install -c conda-forge librosa
```

### Building from source

To build librosa from source, say 
```
python setup.py build
```
Then, to install librosa, say 
```
python setup.py install
```
If all went well, you should be able to execute the following commands from a python console:
```
import librosa
librosa.show_versions()
```
This should print out a description of your software environment, along with the installed versions of other packages used by librosa.

📝 OS X users should follow the installation guide given below.

Alternatively, you can download or clone the repository and use `pip` to handle dependencies:

```
unzip librosa.zip
python -m pip install -e librosa
```
or

```
git clone https://github.com/librosa/librosa.git
python -m pip install -e librosa
```

By calling `pip list` you should see `librosa` now as an installed package:
```
librosa (0.x.x, /path/to/librosa)
```

### Hints for the Installation

`librosa` uses `soundfile` and `audioread` to load audio files.

📝 Note that older releases of `soundfile` (prior to 0.11) do not support MP3, which will cause librosa to fall back on the `audioread` library.

### `soundfile`

If you're using `conda` to install librosa, then audio encoding dependencies will be handled automatically.

If you're using `pip` on a Linux environment, you may need to install `libsndfile`
manually.  Please refer to the [SoundFile installation documentation](https://pysoundfile.readthedocs.io/#installation) for details.

### `audioread` and MP3 support

To fuel `audioread` with more audio-decoding power (e.g., for reading MP3 files),
you may need to install either *ffmpeg* or *GStreamer*.

📝*Note that on some platforms, `audioread` needs at least one of the programs to work properly.*

If you are using Anaconda, install *ffmpeg* by calling

```
conda install -c conda-forge ffmpeg
```

If you are not using Anaconda, here are some common commands for different operating systems:

- ####  Linux (`apt-get`): 

```
apt-get install ffmpeg
```
or
 
```
apt-get install gstreamer1.0-plugins-base gstreamer1.0-plugins-ugly
```
- #### Linux (`yum`):
```
yum install ffmpeg
```
or


```
yum install gstreamer1.0-plugins-base gstreamer1.0-plugins-ugly
```

- #### Mac: 
```
brew install ffmpeg
```
or

```
brew install gstreamer
```

- #### Windows: 

download ffmpeg binaries from this [website](https://www.gyan.dev/ffmpeg/builds/) or gstreamer binaries from this [website](https://gstreamer.freedesktop.org/)

For GStreamer, you also need to install the Python bindings with 

```
python -m pip install pygobject
```
