Are these files only effective if listened to regulariky or would I be able to just listen to a file every once in awhile and still expect results (though over a considerably longer period of time)
Also if anyone could recommend some good sound recording/editing software that I could use to splice some of these files together so I don't have to sit through multiple inductions... Prefferably something free or a trial that doesn't have any restrictions that would get in the way too much
