Pre-built packages for Windows, macOS, Linux and FreeBSD are available at



fre:ac is distributed in two variants, an .exe file containing a setup wizard or alternatively a .zip archive that contains just the application without an installer. If you downloaded the .exe installer, simply run it and the setup wizard will guide you through the installation process creating start menu icons that will run fre:ac. If you downloaded the .zip package, please extract/move the contents to a location of your choice and run freac.exe to start fre:ac.


fre:ac is distributed as an Apple Disk Image (.dmg) file. To install it, open the .dmg image and drag the fre:ac application to a location of your choice like the desktop or the Applications folder. Then double click the application to start fre:ac.

Alternatively, users of the package manager MacPorts may install fre:ac using the following command:

sudo port install freac


fre:ac is available as a Snap, Flatpak or AppImage package. The Snap and Flatpak versions can be found and installed from the respective app stores. Please note that these versions run in restriced environments and might offer limited functionality. The AppImage package must be marked as executable after downloading using the following command:

chmod a+x freac*.AppImage

The AppImage can then be executed to start fre:ac.


fre:ac is distributed as a .tar.gz archive. Please extract the contents to a location of your choice and execute the freac binary to start fre:ac.


fre:ac depends on the BoCA audio component framework and the smooth Class Library. Please build and install those first.

Development packages for the following libraries need to be installed in order to build smooth, BoCA and fre:ac:

  • For the smooth Class Library: libbz2, libcurl, libfribidi, libgtk+3.0, libjpeg, libxml2
  • For the BoCA component framework: libcdio, libcdio-paranoia, libexpat, libpulse (Linux only), liburiparser
  • For fre:ac itself: libudev (Linux only)

When the dependencies are met, run make followed by sudo make install for smooth, BoCA and fre:ac respectively.

You should then be able to run fre:ac using /usr/local/bin/freac and the command line interface using /usr/local/bin/freaccmd.
