I have a years worth of sermons from my local church and they would like to add a 30 second trailer to each sermon. Something like “Thanks for listening to this sermon from xx church located in xx, we would like to invite you…”
Anyways, I am searching for a program that will add the trailer on every single mp3 in a subdirectory without messing up the ID3 tags.
Is there something like that? I have seen a few that will do this manually, but that would take a lot of time with 4 services a week.
