fre:ac audio converter

This quick tutorial is going to show you how to install the free ‘fre:ac’ audio converter in Ubuntu and manually create app shortcut to be able to launch it from Unity Dash, Gnome app launcher, or other app launcher.

fre:ac is a free audio converter and CD ripper works on Windows, Mac OS, Linux, and FreeBSD. It offers Linux packages but lacks application shortcut.

Download fre:ac:

First download the latest version of the audio converter from the link below:

Download fre:ac for Linux

Select download:

  • freac-yymmdd-linux.tar.gz package for 32-bit system.
  • freac-yymmdd-linux-x64.tar.gz package for 64-bit system.

Then extract it. In the case below, I downloaded the 64-bit tarball:

You can now launch the audio converter by run the executable file from its context menu:

Create app shortcut for fre:ac audio converter:

To be able to launch the software from Unity Dash, Gnome app launcher, or other app launcher, you have to manually create an app shortcut for fre:ac.

To do so, open terminal via Ctrl+Alt+T or from app launcher, and do following steps:

1. Move the source folder to /opt/ directory for global use by running command:

sudo mv ~/Downloads/freac-*-linux /opt/freac-linux

Input your password (no visual feedback while typing due to security reason) when it asks and hit Enter.

Then change the ownship via command:

sudo chown -R root:root /opt/freac-linux

2. Create a symbolic link to the executable file, so you can easily run command freac to launch the software:

sudo ln -s /opt/freac-linux/freac /usr/bin/freac

3. Finally run command to create and edit a .desktop file for the audio converter:

gksudo gedit /usr/share/applications/freac.desktop

And paste below lines into the file and save it.

[Desktop Entry]
Name=freac
GenericName=freac audio converter
Comment=fre:ac free audio converter
Exec=env LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/freac-linux/ freac %f
Icon=/opt/freac-linux/icons/freac.png
Terminal=flase
Type=Application
Categories=Audio;
MimeType=application/ogg;application/x-extension-mp4;application/x-flac;application/x-matroska;application/x-ogg;audio/ac3;audio/mp4;audio/mpeg;audio/ogg;audio/x-flac;audio/x-matroska;audio/x-mp3;audio/x-mpeg;audio/x-vorbis;

It’s important to add variable env LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/freac-linux/ to the value of Exec, or it won’t launch the software and output error:

freac: error while loading shared libraries: libsmooth-0.8.73.so.0: cannot open shared object file: No such file or directory

4. Finally launch fre:ac audio converter from app launcher (might need log out and back in) and enjoy!

How to Remove:

To remove fre:ac audio converter, simply remove the source folder, symbolic link, and app shortcut by running following command:

sudo rm -rf /opt/freac-linux /usr/bin/freac /usr/share/applications/freac.desktop

GIMP extra color palettes

GIMP, the popular free and open-source cross-platform image editor, now is available as Snap app for Ubuntu 14.04, Ubuntu 16.04, and higher.

GIMP has been made into the beta channel of Ubuntu Snappy Store for testing for days. Now the latest GIMP 2.8.22 is available in stable channel:

1. For Ubuntu 14.04 and Ubuntu 16.04 users that have not installed any Snap app, install snapd daemon first via command (open terminal via Ctrl+Alt+T):

sudo apt-get install snapd

Input your password (no visual feedback while typing due to security reason) and hit Enter.

2. Then install GIMP snap app either via command:

sudo snap install gimp

Or by using Ubuntu Software Center (need login):

The snap app can co-exist with the traditional GIMP package. So if you have both versions installed, you have to launch GIMP Snap app via following command since the app launcher opens the traditional one:

/snap/bin/gimp

How to Remove GIMP Snap app:

To remove the app, simply run command in terminal:

sudo snap remove gimp
