Audacity is a cross-platform audio editor that provides some of the same abilities as store-bought audio editing programs such as Peak Express. This program has more capabilities than merely cutting and copying files; Audacity also can record from an input source, which goes along with mixing multiple audio files together. This is the same type of utility that Audio Production Studios use, although they use a hugely expensive program called Pro Tools.
I downloaded the source and compiled it myself, but most of you should be able to download the packages. You can use a package manager such as Kpackage or Synaptic to install Audacity, if it is available for your distribution. You also can install the packages with apt-get or yum at the command line. Finally, you can download Audacity as RPM or DEB packages and install them locally at the command line. For more information on downloading Audacity, visit audacity.sourceforge.net.
