A binary version of Eisenkraut for Linux, OS X and Windows is provided through Bintray.
setting up and running
Eisenkraut uses the SuperCollider server as the audio playback engine. You need to install a recent SuperCollider 3 version to run this software. The recommended version is SuperCollider 3.6.3 or newer. On Linux Debian, you should be fine with
sudo apt-get install supercollider.
To launch Eisenkraut, you can use the
Eisenkraut.command shell script. On a Linux desktop system, you may copy
~/.local/share/applications in order to be able to place Eisenkraut in your desktop's application bar. Make sure you open this file with a text editor and change paths in the
Icon entries to match your installation location. Future versions will hopefully provide an automatic installation procedure to do that work for you. Installing the
.desktop file means you can open sound files directly from the desktop or file manager (Nautilus).
After launching Eisenkraut for the first time, make sure that the "SuperCollider Server (scsynth)" field in the audio preferences is pointing to the valid
scsynth.exe (on Windows) file! On OS X, newer SuperCollider versions "hide" the
scsynth command line tool inside the
SuperCollider.app bundle. So the correct path will be something like
Also note that, by default, the audio server is not automatically booted, so you need to press the "Boot" button in the main window to launch the server and be able to actually hear the sound file when playing it back. There is a preferences switch to enable automatic booting.
Eisenkraut can be build from source with sbt version 0.13. It requires Java 1.6, and library dependencies are currently included as jars in the
If you do not have or wish to install sbt on your system, a shortcut is to use the provided Unix (OS X and Linux) script
sbt which comes in the main folder. It may be invoked as
./sbt and will automatically download the correct
sbt-launch.jar version and place it in the main Eisenkraut directory, the first time it is executed.
To build on Linux or Windows:
$ sbt assembly
The result will be
Eisenkraut.jar. This should be double-clickable, and otherwise can be launched with
java -jar Eisenkraut.jar. The preferred way, however, is to use the
Eisenkraut.command shell script which will give the application more memory.
To build on OS X:
$ sbt appbundle
The result will be
Eisenkraut.app in the main directory.

A lot. Here are some suggestions:
- Still need to integrate FScape (more a job about FScape than about Eisenkraut)
- Finding a way to edit with simultaneous video display (might be a separate app synchronized through some kind of OSC transport)
- Optionally saving meta-information with the sound files (e.g. a separate XML file), like panorama settings, window bounds etc.
- Finishing sonogram functionality (needs decimation and must be editable)
- Improving SuperCollider interface and classes
- etc. etc.
