Tenacity

What Tenacity is

Tenacity is a free, open-source multitrack audio editor and recorder developed by volunteers. It records from real or virtual audio devices and processes audio up to 32-bit float. Editing includes multitrack timeline work at arbitrary sample positions, keyboard editing, and support for screen readers and narration. It imports and exports a wide range of audio formats, with FFmpeg available to extend format support. Plugin options include VST, LADSPA/LV2, and AU; scripting includes Nyquist and named pipes for languages such as Python and Perl. Tenacity also provides signal analysis tools. The project describes uses including music recording, podcast editing, and academic signal analysis. It runs on Windows, macOS, Linux, *BSD, and Haiku, and is licensed under GNU GPL version 2 or later. Linux distribution options include Flatpak and AppImage, though AppImage-specific issues are unsupported. The manual notes that the track area is not hardware accelerated and can use substantial CPU resources. Project files may also grow unexpectedly large, and there are no input or output volume controls because the Mixer Toolbar was removed.
