The Tenacity Manual


Welcome to the Tenacity Manual! This manual details everything about Tenacity, from general concepts to the very technical details of how something works.

Tenacity is a free and open source audio editor forked from the popular audio editor Audacity. Tenacity is licensed under the GNU General Public License version 2 or later. It contains the following features:

  • Recording from audio devices, real or virtual.

  • Support for importing from and exporting to a wide range of audio formats, extensible with FFmpeg.

  • High quality audio processing, including up to 32-bit float audio support.

  • Extensibility with support for plug-ins, providing support for VST 2, LADSPA/LV2, and AU plugins.

  • Support for scripting in the built-in scripting language Nyquist, or in Python, Perl, and other languages with named pipes.

  • Editing arbitrary sampling and multi-track timeline.

  • Accessibility including editing via keyboard, screen reader support and narration support.

  • Tools useful in the analysis of signals, including audio.

Tenacity does not have a single application when it comes to audio processing. Musicians recording real instruments can make a song in Tenacity, podcasters can edit their episodes in Tenacity, and even academic researchers can analyze signals using Tenacity. We don’t intend to focus Tenacity on a single area of audio processing, but rather, we intend to focus Tenacity over audio processing in general, including the aforementioned applications. Therefore, we intend to focus this manual on all possible use cases and applications of Tenacity.
