Trim audio file using python ffmpeg

Question

I am trying to simply input an audio file, trim the first 5 seconds and than output it into a directory. I am using jupyter notebook.
This is what i did:

import ffmpeg audio_input = ffmpeg.input('input.mp3') audio_cut = audio_input.audio.filter('atrim', duration=5) audio_output = ffmpeg.output(audio_cut, 'out.mp3')

I get no errors, but no results as well. I also noticed even if i enter a non-existent file name or path i still don't get any errors.

Did you try to convert the mp3 to raw PCM audio before cutting it ? I don't thing you can manipulate mp3 without decompressing it first. — dspr

I haven't tried that. Could you show me how it's done? I am pretty new to this. Or a reference would be helpful — Mehrudin Sabani

The first thing you should do is to convert your file to a .wav file (if you don't have an application for that there are plenty of websites doing that online) and try again with ffmpeg.input('input.wav) instead to see if the problem is really there. — dspr

Add a line of code: ffmpeg.run(audio_output)

import ffmpeg audio_input = ffmpeg.input('input.mp3') audio_cut = audio_input.audio.filter('atrim', duration=5) audio_output = ffmpeg.output(audio_cut, 'out.mp3') ffmpeg.run(audio_output)
