Delay audio for a few seconds at the start of audio files (using ffmpeg)

Question

I have been trying to get lots of wav files delayed by 2 seconds at the start using ffmpeg. And so far, even though I have read the manual, I was not able to get it working. Here is my command:

for %%A in (*.wav) do (
ffmpeg -i "%%A" -itsoffset 00:00:02 "%%~NA"1.wav )

And nothing is being changed. Files are simply getting copied. I also tried the same with mp3 files. I also tried mkv and avi (to make sure it was not a container writing issue), but it gives the same result also.

Command is same here and here, but it does not work. Please, help.

You must put -itsoffset BEFORE you specify input. So:

ffmpeg -itsoffset 00:00:02 -i "%%A" "%%~NA"1.wav
