Latest commit 123d0fd Feb 27, 2018


We will focus on three independent problems. These are:

  1. Monaural source separation - Using source contrastive estimation (submitted to SiPS 2017).
  2. Removing a source (whose location is static) that is dynamic and loud.
  3. Multiple moving sources (i.e., the channel changes with time)
  4. Standoff distance acoustic enhancement (dynamic gain adjustment in low SNR)

This project will be primarily an analysis of cost functions (in supervised and unsupervised settings) that can be used in order to denoise and isolate signals. The resulting algorithms of interest will be a mix of cost function resembling ICA and simulated beamforming methods.

Source Separation

Source separation is currently on a branch that will not run in the current code base. We have released a previous version (release 1) that does accomodate for it. This can be run out of the box with two shell scripts:

  1. : Per the above comment, this will checkout the release that is able to run source separtion, provided you have cloned the original repository. Then it will compile a Dockerfile (that resembles the one currently in the repository.) This will download models from Dropbox, which take the most amount of time. Then, it will revert back to the master. There might be some tricks you need to do to get yourself back to the right git state. The docker container is called magnolia-demo-r1, for the first release.

  2. : This will actually run After you type in this command, go to your localhost at port 5000. (Type in localhost:5000 into your browser.)
