Analyze, visualize and process sound field data recorded by spherical microphone arrays.
The sound_field_analysis toolbox (short: sfa) is a Python port of the Sound Field Analysis Toolbox (SOFiA) toolbox, originally by Benjamin Bernschütz. The main goal of the sfa toolbox is to analyze, visualize and process sound field data recorded by spherical microphone arrays. Furthermore, various types of test-data may be generated to evaluate the implemented functions.
The package is pure python and PEP8 compliant (except line-length). Please expect things to be slow for now and for the API to break, as the development is still very much ongoing.
We use Python 3.5 for development. Chances are that earlier version will work too but this is currently untested.
The following external libraries are required:
You can simply install sfa through pip (pip install sound_field_analysis).
We highly recommend the Anaconda python environment. Once installed, you can use the following steps to create a new environment with the sfa toolbox.
- Create a new environment: conda create --name sfa numpy scipy plotly
- Activate this environment: source activate sfa
- Install from pypi: pip install sound_field_analysis
Soon, you may also install directly from the conda-forge channel using conda install -c conda-forge sound_field_analysis.

The sound_field_analysis toolbox is based on the Matlab/C++ Sound Field Analysis Toolbox (SOFiA) toolbox by Benjamin Bernschütz. For more information you may refer to the original publication:
