Something like this might work:   Is there a something that can detect audio for the app inventor.  

however you have a huge problem; App Inventor apps currently cannot work as a service (run in the background) so when the phone is 'awake' this technique might work, however when the phone goes to sleep, it will no longer respond.

However, you cannot " record a sound, check if the sound is the same as a saved sound the trigger an action".. unless you develop a very sophisticated extension.

Here are some ways you might be able to do this with Android Studio    https://www.google.com/search?q=clap+java+code&oq=clap+java+code&aqs=chrome..69i57.3087j0j7&sourceid=chrome&ie=UTF-8  by building an extension or coding your Project using Android Studio.
