File Timestamp Monitor

I want to monitor a text file and when its timestamp changes play a sound. I first though of doing this with Task Scheduler, but I don't see a way to directly monitor a file timestamp with Task Scheduler. I do see that this can be done with PowerShell, although I am uncertain if I can just start a PowerShell script and have it run all time time or if it's something that needs to be managed with Task Scheduler. The other option I'm looking at is Autohotkey, which would be helpful since I might want to actually look in the file to see what the event was that case the timestamp to change.

Just asking for general feedback on the best way to do this, or if there might be something else.

Win 10 Home (17763)

This does what I wanted.

Code:

#singleinstance force
#persistent
filepath= C:\FileToMonitor.txt

settimer, check_date, 60000 ; every minute

check_date:

FileGetTime, current_modified , %filepath%, M
if (prev_modified = current_modified)
{
return
}
SoundPlay C:\Windows\Media\Ring01.wav

prev_modified = %current_modified%
return
