A snapshot is a representation of the current state of a session. In a nutshell, it’s like versioning your project by giving every version a meaningful, descriptive name. Even though it’s not really exposed to users, every session always has at least one snapshot which is whatever you have there at the moment.
Let’s say you recorded a song in your home studio and you are trying different arrangements to see which one works best. Instead of creating multiple sessions and copying files between them, you can make snapshots every time you think you have something worth preserving. At any point in time, you can save the current state of the session and switch to an earlier snapshot to compare your arrangements.
Ardour provides two commands in the Session menu to create a snapshot:
By default the program will name the new snapshot according to the current date and timestamp of your system. If you wish, you can change the name to one that more meaningfully corresponds to the session you are working on.
You can recall a saved snapshot via the Snapshots tab in the area on the right:
There you see a few snapshots that we created, and the my_session entry represents the original state of our session.
Click on any snapshot from the list to reload it.
Sometimes it is helpful to have a default starting point for new sessions, for example, for a setup that you use all the time when starting a new project. To learn how to do this, please continue to the next section called Saving a Template.
