Lossless Cut with ffmpeg

As another addendum to my notes on image optimization, here is how to cut a piece of audio or video as losslessly as possible with just ffmpeg on the commandline.

In this example we want the piece of audio from 1:30 to 2:00.

fmpeg -ss "1:30" -i audio-full.m4a -c copy -t "2:00" audio-cut.m4a
