I got a problem for my sound track. I got an X mp3 file and Y mp3 file. I want to make just one file with X goes first, then 20 minutes silent followed, then Y mp3 at the end.
Does anyone know how can I do it ? I only can find the mp3 cutter/ ripper, but not a joint tool to do it. Last, I have no idea how can I make a 20 min silent period in between X and Y. Te output should be just one file, all in one file.
