Sox：在mp3文件末尾修剪

Question

I'm struggling a bit with sox. I am trying to simply cut off 1.2 seconds of the end of a file. I know there is a trim function in sox, but I am not sure how to use it so it cuts off the exact time at the end? I know it works like this roughly:

sox input output trim <start> <duration>

However, the only solution I could come up with would be something like this (Pseudocode) :

sox input output trim <length of whole mp3 file -1.2 seconds> <1.2 seconds>

Answer 1

弄清楚了：

sox input output trim 0 -1.2
