Muse Group's audio editor (3.7.8 on 2026-08-24). GitHub LICENSE.txt: the app is GPLv3; many files are GPLv2-or-later; docs are CC-BY 3.0. FAQ: it "will always remain free". Windows/macOS installers push MuseHub; "Download without MuseHub" links exist. This catalog already prefers tenacity for the telemetry/terms fork. Use Audacity if you need the Muse build. GPL covers the program. Edits inherit the source clip's license.

Version left as bare GPL-3.0 deliberately. The project says "licensed GPLv3" while noting most files are GPLv2-or-later, and VST3-related code constrains the combined work, so no single SPDX identifier is stated. Checked 2026-09-22.
