Precompiled versions of the application for various operating systems are available for a fee. Per the developer's website: If you want the convenience of using our ready-to-run version and/or for support from Ardour developers and experienced users, we ask that you pay something for this. If you don't want to pay for a ready-to-run version, then you'll need to get the source code and build it yourself. We do not provide assistance with this process and particularly on Windows and macOS this can be challenging and take a long time. Also, for Windows, there are no instructions.
