 The [[https://manual.ardour.org/setting-up-your-system/the-right-computer-system-for-digital-audio/|Ardour manual]] has a interesting introduction about getting the right computer system for digital audio. Below that article there is also a (somewhat Windows oriented) [[https://www.youtube.com/watch?v=GUsLLEkswzE| video]] by Richard Ames, which could be helpful to get a idea which things are involved for this topic. Summary: lots of things are involved for a well performing real-time audio workstation. It's not simply a matter of buying a computer with massive CPU and memory power, as the coming sections on this page shows. The [[https://manual.ardour.org/setting-up-your-system/the-right-computer-system-for-digital-audio/|Ardour manual]] has a interesting introduction about getting the right computer system for digital audio.

 This way you can restore the original file in the case you made such a typo that the system has become unbootable. The procedure of recovering an unbootable system itself is beyond the scope of this Wiki but there are plenty of resources that explain this in detail. This way you can restore the original file in the case you made such a typo that the system has become unbootable.
