No, Audacity is licensed as GPLv2+.

Audacity was bought in 2021 by Muse Group, and a few weeks later, they announced that they would introduce Google Analytics and Yandex-based “telemetry”. After strong criticism by the community, Muse Group backtracked, emphasized their commitment to the GPL license, dropped their plans to include Google/Yandex tracking, and instead opted for a self-hosted solution for bug reports and update checks. Both can be disabled, and some distributions disable them by default.

Still, a few forks emerged, Tenacity is the only one that is still actively being maintained. The last commit is from today, but their repository is at 16k commits, compared to 21k commit for Audacity, so it seems the two projects have diverged.
