The Ubuntu Software Centre has an older version and downloading Audacity from the website gave me a folder that doesn't seem to have a binary to start the program. How do I install version 2.1.0 in Ubuntu 14.10?
You have to compile Audacity from source. The "README.txt" as part of the 2.1.0 package states that:
To compile on Linux, Mac OS X and other Unix systems, execute these commands:
./configure make make install # as root
Running these commands should install Audacity 2.1.0 onto your system providing you have the necessary dependencies to compile and install it. The Audacity Sourceforge page states that:
The wxWidgets library is required. Audacity 2.1.0 requires wxGTK 2.8.12. The libsndfile library is also required and is included in Audacity obtained from SVN. Installation of other libraries is optional.
CMake is required to build libsoxr which is now the Audacity default resampling library.
Ubuntu should already have the required dependencies for Audacity, however you need development packages in order to compile. You could do this manually using
apt-get install but because Audacity is already in the Ubuntu repositories we can run
apt-get build-dep audacity to install all of the required development packages for us.
Now all you need to do is configure, make, and install Audacity as described in the readme file.
Run these commands in a terminal
sudo add-apt-repository ppa:ubuntuhandbook1/audacity sudo apt-get update sudo apt-get install audacity
