Another application Ubuntu lacks is an editor for digital audio. Which admittedly makes sense, as not that many people need to edit digital audio on a regular basis. If you do need to edit audio files, however, the Audacity application is excellent. And it’s also available for Ubuntu.
To install Audacity, make your way to the Terminal window and type this command:
sudo apt-get install audacity
This will download and install Audacity and its dependencies from the Ubuntu repositories. Once finished, you can run Audacity by going to the Dash, searching for “audacity”, and clicking on the Audacity icon.
However, the default install of Audacity lacks the ability to export its projects as an MP3 file. To gain that functionality, you’ll need to install the LAME library, which gives Audacity the ability to encode MP3 files. Note that the ownership of the MP3 patents remain in some dispute, so there may be liability issues in using LAME. However, if you’re in the legal clear, you can use this Terminal command to install the LAME library:
sudo apt-get install libmp3lame0
This will gave Audacity the ability to export projects as MP3 files.
