"Audacity is no mere virtual jukebox. Sure, it'll play music,
but what it's really there for is editing audio files -- everything
from MP3s you may have in your collection to recordings you make
yourself. The multitrack editor isn't what you'd call a pro-level
tool, but its healthy menu of effects and clean-up utilities makes
it an easy-to-use and effective app for the amateur soundsmith.
"Audacity, an open source multitrack audio editor, has versions
for Linux/Unix, MacOS and Windows. If all you do with audio files
is play them, then Audacity could be much more than you need. This
is not an application for organizing your music collection.
"It has no fancy search and play functions. Sure, you can use it
to listen to your music collection. But Audacity's main focus is on
importing and exporting audio files. Its toolset delves into the
realm of editing sound tracks in much the same way graphic editors
let you manipulate images"
