Just read about it this morning on my mobile phone, but as a supporter of Ardour I had it since yesterday already – and installed it on both Linux and Windows:
I sat down with the guitar to record a bit with it, but got interrupted after 15 minutes or so – can’t always record with a microphone. But Ardour works as a charm, I’m using it since at least 2017 and couldn’t wish for anything else really.
A download of the binary file costs an amount of your own choice (starting at 1$/1€ I think), but it’s worth it. If you’re on Linux, you might have an older version from your repositories, or even this one from third party offerings like KXStudio and the likes.
Enjoy…
