Trim and Fade audio files

[fabs68]

I'm trying to trim a list of audio files (45 seconds starting from 15 seconds) and then apply a fade-in/out of 3 seconds. By pressing the "Trim files" button and with the settings of the uploaded image I only obtain the trimmed files but there isn't the fade-in fade-out. Am I doing something wrong in the settings or is it possible only in two steps (Trim files + Sequential encoding)?

I wasn't able to get it to work through the interface, perhaps it's worth contacting the programs author about this,
but you can add the ffmpeg commands manually to get what you want

-vn -ss 00:00:15 -t 45 -c:a libmp3lame -b:a 224K -ac 2 -af "afade=t=in:st=15:d=5,afade=t=out:st=55:d=5"

Thank you very much, everything is working in the way you've suggested.
Can you also suggest me a good place where I could download a complete guide with all ffmpeg commands?
Thank you again for you help davexnet!
