How to cut off the first few seconds of several tracks at once?

Question

Sound processing

There are about 100 mp3-nis in the language learning course, and everyone has a 6-second musical insert at the beginning. I want to remove it, otherwise the brain will boil from it after 3 days of study.
I don't want to edit each file manually either. I assume that there is simply a solution in three buttons.

Answer 1

for %n in (*.mp3) do ffmpeg -ss 6 -i %n -c:a copy "out/%~nxn" команда для нескольких файлов.
