How do I join multiple audio files into one with regular delays in between using FFMPEG?
I have the following audio files in my folder:
01.mp4 02.mp4 03.mp4 04.mp4 ... 27.mp4
They’re all audio-only files. I want to use FFMPEG to concatenate them with a 3-second spacing/silent pause in between each track. The files are of different lengths btw. I have tried to use
ffmpeg -i "concat:01.mp4|02.mp4|03.mp4|04.mp4|05.mp4|06.mp4|07.mp4|08.mp4|09.mp4|10.mp4|11.mp4|12.mp4|13.mp4|14.mp4|15.mp4|16.mp4" -filter_complex "[0:a]apad=pad_dur=3[aout]" -map "[aout]" output.mp4
but it only copied
01.mp4 with an added 3-second silence at the end.
How can I achieve this in Windows cmd Command Prompt, preferably in one line?
