ffmpeg cut audio file


To cut audio from a big audio file we can use ffmpeg.

In following example I am trying to cut audio from input.mp3 file. Here I am cutting audio from 30th second to 50 seconds.

ffmpeg -ss 00:00:30.0 -t 00:00:20.0 -i input.mp3 -acodec copy -vcodec copy -async 1 output.mp3


-ss to starting time

-t to number seconds/minutes/hours after starting time.

-acodec copy will make output.mp3 with same properties (bitrate) as input.mp3
