libsoni: A Python Toolbox for Sonifying Music Annotations and Feature Representations

libsoni is an open-source Python toolbox tailored for the sonification of music annotations and feature representations. By employing explicit and easy-to-understand sound synthesis techniques, the toolbox offers functionalities for generating and triggering sound events, enabling the sonification of spectral, harmonic, tonal, melodic, and rhythmic aspects. Unlike existing software libraries focused on creative applications of sound generation, the toolbox is designed to meet the specific needs of MIR researchers and educators. It aims to simplify the process of music exploration, promoting a more intuitive and efficient approach to data analysis by enabling users to interact with their data in acoustically meaningful ways.

See the API documentation for a detailed view of the provided functions in libsoni.

Installation Guide

We outline two primary methods for setting up libsoni using pip and setting up a dedicated environment.

Method I: Installing with pip

Utilize Python's package manager, pip, for a straightforward installation of libsoni:

pip install libsoni

Note: We advise performing this installation within a Python environment (such as conda or a virtual environment) to prevent any conflicts with other packages. Ensure your environment runs Python 3.7 or higher.

Method II: Setting Up a Conda Environment

Alternatively, you can create a conda environment specifically for libsoni by downloading this repository and installing the library in development mode. This approach not only installs libsoni but also includes necessary packages for running the demo notebooks with jupyter. One way to achieve this would be using the following commands:

conda create -n libsoni python=3.11 flit
conda activate libsoni
flit install --symlink --deps all

Running Example Notebooks

To explore libsoni through example notebooks:

1. Install libsoni: Prior to cloning the repository and running the notebooks, ensure libsoni and its dependencies are installed (as described above).
2. Clone the repository: Download the libsoni repository to your local machine using the following git command:

git clone https://github.com/groupmm/libsoni.git

3. Install Jupyter: If not already installed via the conda environment setup, install Jupyter to run the notebooks:

pip install jupyter

4. Launch Jupyter Notebook: Start the Jupyter notebook server by executing:

jupyter notebook

This will open a browser window from where you can navigate to and open the example notebooks.
