Important note: This is project is in pre-APLHA state, do not expect it to be usable in any form or shape.

  • It has bugs.
  • It does not do a lot of useful things.
  • There is no documentation.
  • And most importantly: the save format is not finalized and will change in incompatible ways, i.e. you will not be able to open your work from older versions.

This project is currenly only designed to run on Linux desktops. No effort has yet been made to make it run on anything else than Ubuntu 16.04 and 17.10 (which are the distributions used for development).

Getting Started

These instructions are not targetted at end users. There are not prebuilt binary packages, which you could just install, so you have to build from source. It is assumed that you're moderately experienced with software development on Linux.

First grab the latest source code:

git clone
cd noisicaa

Then install the deb packages that are needed to build and run it:

sudo apt-get install $(./listdeps --system --build)

For the first time setup, create a new virtualenv:

python3 -m venv ENV
. ENV/bin/activate
pip install --upgrade pip wheel

And populate it with a bunch of python packages that noisicaä uses:

pip install $(./listdeps --pip --build)

Now you should be ready to build it:

python3 build

There is currently no way to install it, so you can only run it from the build directory using


Everytime you open a new bash to work with it, you have to activate the virtual environment using

. ENV/bin/activate
