Free/Open-source Digital Audio Editors

A digital audio editor is a computer application for audio editing or digital audio manipulation. Usually, a digital audio editor allows the user to record and edit audio, mix multiple sound sources/tracks, apply simple or advanced effects or filters, playback sound, and convert different audio file formats and different sound quality levels.

Sound engineers, audio producers, and those involved in sound recording and reproduction are mostly using digital audio editors nowadays. I have here a list of well-known free/open-source digital audio editors for the music enthusiasts, professionals and non-professionals alike. I hope some of these applications will somehow help increase their productivity.
