Download

Grab either the AppImage or the Debian package from the latest release.

AppImage — no installation needed, just make it executable and run it:

chmod +x Audionaut-*.AppImage
./Audionaut-*.AppImage

Debian package (Debian/Ubuntu and derivatives) — install with apt, which also resolves dependencies:

sudo apt install ./audionaut_*_amd64.deb

Grab the installer (Audionaut-<version>-Setup.exe) from the latest release and run it.

The installer is not yet code-signed, so Windows SmartScreen may warn on first launch — choose More info → Run anyway.
