It is the time to look for a fork due to recent changes to the Audacity privacy policy (GitHub issue New privacy policy is completely unacceptable! #1213), Contributor License Agreement, and telemetry implementation.

There are two notable Audacity forks: Tenacity and Audacium.

Tenacity

GitHub repository: https://github.com/tenacityteam/tenacity
Official website: https://tenacityaudio.org

Tenacity is an easy-to-use, cross-platform multi-track audio editor/recorder for Windows, MacOS, GNU/Linux and other operating systems and is developed by a group of volunteers as an open source software that respects user privacy.

Audacium

GitHub repository: https://github.com/SartoxOnlyGNU/audacium
Official website: https://audacium.seb1g.live

Audacity fork without Telemetry and with new features.

Sneedacity

GitHub repository: https://github.com/Sneeds-Feed-and-Seed/sneedacity
Official website: https://sneedacity.org

A free, privacy-respecting, audio editor.

Additional notes

There is a lot of heat right now, keep a cool head.

You need to compile these applications, but this is a simple and straightforward process (see BUILDING.md file) which is the same in both cases.
