EM algorithms for integrated spatial and spectral models.

Project description

Blind Source Separation (BSS) algorithms

Build Status Azure DevOps tests Azure DevOps coverage MIT License

Fork note : The original repo has been modified to allow a partial release of the evaluation utilities on PyPI under the name pb_bss_eval. All the credits goes to the original authors (see here).
As can be seen in the, only the evaluation sub-package can be installed and is released on PyPI. To install it, just run :

pip install numpy Cython  # required for pesq install
pip install pb_bss_eval

This repository covers EM algorithms to separate speech sources in multi-channel recordings.

In particular, the repository contains methods to integrate Deep Clustering (a neural network-based source separation algorithm) with a probabilistic spatial mixture model as proposed in the Interspeech paper "Tight integration of spatial and spectral features for BSS with Deep Clustering embeddings" presented at Interspeech 2017 in Stockholm.

  Booktitle                = {INTERSPEECH 2017, Stockholm, Sweden},
  Year                     = {2017},
  Month                    = {Aug}


Install it directly from source

git clone
cd pb_bss
pip install --editable .

We expect that numpy, scipy and cython are installed (e.g. conda install numpy scipy cython or pip install numpy scipy cython).

The default option is to install only the necessary dependencies. When you want to run the tests or execute the notebooks, use the one of the following commands for the installation:

pip install --editable .[all]  # Without a whitespace between `.` and `[all]`
pip install git+[all]
