Cropping mp3 files with FFmpeg

Today, I was trying to find a free app for cropping a mp3 sound file. And I found a simple one with CLI. The FFmpeg is a multimedia files handler and it is pretty complex. But to do this task we will use the following parameters:
  • -t chop after specified number of seconds
  • -ss chop until specified number of seconds
  • -acodec copy to maintain encoding and sampling rate
  • -i use file as input file
And the final command was something like this:

ffmpeg -acodec copy -y -t $start_at -ss $ends-at -i $inputfile.mp3 $outputfile.mp3
