Not just no, but Hell No!
Do not rely upon recording for anything – it's like hunting and pecking instead of typing and fraught with misspellings...
Recording can be useful for various things like recording clicks or menu selections – but you have to understand KM a bit – before you can tweak the results as necessary to do the right thing.
More specifically, watch for an audio file -> open a loudness meter app (if it isn't already running) -> load the file into the app -> perform any subsequent task I require based on the reading given by the app.
- How many files will be added to the watched folder at once?
- What app?
- What reading?
- How is the reading presented?
If you haven't read these they're worth a couple of minutes of your time.
