Our take
Ardour is overkill for trimming a podcast and exactly right for producing a record. It is a true DAW with the depth to rival commercial tools, and the project has been developed continuously since the early 2000s. That depth is also the warning: it is the steepest learning curve in this category, and it assumes you already understand audio routing and signal flow. Choose Ardour if you make music or do serious multitrack work. For quick edits and cleanups, Tenacity is the saner starting point.
