Audacity is my go-to program when I need to edit audio on my system. It is a comfortable to use Open Source application with a feature set that is rivaling commercial sound editors. The developers of Audacity have just released Audacity 2.0 to the public.
The new version as usually is available for all supported operating system, that is Microsoft Windows, Apple Macintosh and Gnu/Linux, and as a source code download. Audacity 2.0 replaces all previous versions of the program, especially version 1.2.6 and 1.3.14, the previous release versions of the audio software. The 1.2.x versions were the stable versions of the program, while 1.3.x beta versions.
Windows users who want to install the new version need to pay attention to the installation process. If they are upgrading to 2.0 from earlier program versions, they need to download and install the latest version of the LAME mp3 encoder for MP3 support.
The developers note that the Windows installer will replace a 1.2.x installation of Audacity, but install alongside 1.3 beta versions. They therefor recommend to uninstall 1.3 versions prior to installing Audacity 2.0.
