System.Diagnostics.Process.Start(ProcessstartInfo) can execute any executable in a separate process and you can kill that process if you take reference of this process in your code. But you can not control that application(.exe) from your application. In your question what i guess that you want to do programming with Adobe Audion(Recording software). In that case you can not do it with just Process.Start method. You needed to download Adobe Audion sdk for programming. I see they have sdk download feature
You should rnd with that api and use it to your application and you can do what they exposed for you as api. Sorry i have no experiance on that sdk. So i do not help you about that sdk integration and programming. You should start rnd with that software site.
