Ardour 2.4.1 - Open Source Digital Audio Workstation

Ardour is an advanced audio software package for recording, editing and mixing audio signals. For example, if you have two or more sound recordings that you would like to combine into a song to be recorded on a CD, you can use Ardour's powerful mixing capabilities to improve or modify the tracks and then merge them into one signal. You can cut and paste sections of tracks to cover up imperfections, etc. Non-destructive editing facilitates unlimited undo/redo operations.

Ardour aims to provide an audio recording system with functionality and performance required by professional users. A flexible routing system makes it possible to connect "anything to anywhere," and can handle all physical I/O ports of your system. Ardour also supports various audio-for-video features, including video-synced playback and pullup/pulldown sample rates.

You can use the Ardour user manual to learn how to run the program and use its features. Download information is available here here.
