### Installing PyWorld with setup.py

Source: https://github.com/jeremycchsu/python-wrapper-for-world-vocoder/blob/master/README.md

This command installs pyworld using the setup.py script. It provides options for installing without root access and tracking the installation directory.

```Shell
python setup.py install
```

--------------------------------

### Installing PyWorld with setup.py (record)

Source: https://github.com/jeremycchsu/python-wrapper-for-world-vocoder/blob/master/README.md

This command installs pyworld using the setup.py script and records the installation directory to install.txt.

```Shell
python setup.py install --record install.txt
```

### Building PyWORLD from Source using Bash

Source: https://github.com/jeremycchsu/python-wrapper-for-world-vocoder/blob/master/README.md

These commands detail the steps to build PyWORLD from source, including cloning the repository, updating submodules, installing dependencies, and installing the package. It assumes git and pip are installed.

```bash
git clone https://github.com/JeremyCCHsu/Python-Wrapper-for-World-Vocoder.git
cd Python-Wrapper-for-World-Vocoder
git submodule update --init
pip install -U pip
pip install -r requirements.txt
pip install .
```

--------------------------------

### Installing PyWorld with setup.py (user)

Source: https://github.com/jeremycchsu/python-wrapper-for-world-vocoder/blob/master/README.md

This command installs pyworld using the setup.py script in user mode, useful when root access is not available.

```Shell
python setup.py install --user
```

--------------------------------

### Installing PyWorld with pip

Source: https://github.com/jeremycchsu/python-wrapper-for-world-vocoder/blob/master/README.md

This command installs the pyworld package using pip. It is a safer method and allows for easy uninstallation.

```Shell
pip install .
```

--------------------------------

### Installation Validation using Bash

Source: https://github.com/jeremycchsu/python-wrapper-for-world-vocoder/blob/master/README.md

This snippet validates the PyWORLD installation by running the demo script. It assumes the user is in the root directory of the cloned repository.

```bash
cd demo
python demo.py
```

--------------------------------

### Building PyWorld extensions in-place

Source: https://github.com/jeremycchsu/python-wrapper-for-world-vocoder/blob/master/README.md

This command builds the pyworld extensions in-place, allowing you to use the library directly from the source directory without installing it globally.

```Shell
python setup.py build_ext --inplace
```

--------------------------------

### Installing PyWorld on Mac with pip

Source: https://github.com/jeremycchsu/python-wrapper-for-world-vocoder/blob/master/README.md

This command installs pyworld on macOS, setting the deployment target to 10.9. This may be necessary to resolve compatibility issues.

```Shell
MACOSX_DEPLOYMENT_TARGET=10.9 pip install .
```

--------------------------------

### Installing PyWorld in editable mode with pip

Source: https://github.com/jeremycchsu/python-wrapper-for-world-vocoder/blob/master/README.md

This command installs pyworld in editable mode using pip, creating links to the source directory instead of copying files.

```Shell
pip install -e .
```

--------------------------------

### Feature Conversion using PyWORLD in Python

Source: https://github.com/jeremycchsu/python-wrapper-for-world-vocoder/blob/master/README.md

This snippet shows how to convert speech into features (f0, sp, ap) using the default arguments of the pw.wav2world function. It requires the pyworld library and takes an audio signal (x) and sampling frequency (fs) as input.

```python
# Convert speech into features (using default arguments)
f0, sp, ap = pw.wav2world(x, fs)
```

--------------------------------

### Uninstalling PyWorld with pip

Source: https://github.com/jeremycchsu/python-wrapper-for-world-vocoder/blob/master/README.md

This command uninstalls the pyworld package using pip.

```Shell
pip uninstall pyworld
```

--------------------------------

### Matplotlib Agg Backend Import

Source: https://github.com/jeremycchsu/python-wrapper-for-world-vocoder/blob/master/README.md

This snippet imports matplotlib and sets the backend to 'Agg'. This is needed in some environments (e.g. remote Linux server) to avoid display issues.

```python
import matplotlib
matplotlib.use('Agg')
```

--------------------------------

### Vocoder Functions using PyWORLD in Python

Source: https://github.com/jeremycchsu/python-wrapper-for-world-vocoder/blob/master/README.md

This snippet demonstrates how to use PyWORLD's vocoder functions to extract speech parameters (f0, sp, ap) and synthesize speech. It requires the pyworld library and takes an audio signal (x) and sampling frequency (fs) as input.

```python
import pyworld as pw
_f0, t = pw.dio(x, fs)    # raw pitch extractor
f0 = pw.stonemask(x, _f0, t, fs)  # pitch refinement
sp = pw.cheaptrick(x, f0, t, fs)  # extract smoothed spectrogram
ap = pw.d4c(x, f0, t, fs)         # extract aperiodicity

y = pw.synthesize(f0, sp, ap, fs) # synthesize an utterance using the parameters
```
