Loudness is a C++ library with Python bindings for modelling perceived loudness. The library consists of processing modules which can be cascaded to form a loudness model.

To build the C++ library you will need:

• libsndfile1-dev >= 1.0.25
• libfftw3-dev >= 3.3.3
• zlib1g-dev >= 1.2.8

To build the Python bindings you will need:

• swig >= 3.0.0
• python-numpy-dev

cd build make sudo make install

The library interface is entirely based on the fantastic AIM-C: https://code.google.com/p/aimc/
