Use ffmpeg to separate audio and video. First check properties of videofile see if your audio is aac or mp3 and write in accordingly below.

ffmpeg -i musica_celestial.mp4

Para extraer el audio:

ffmpeg -i musica_celestial.mp4 -vn -acodec copy audio_musica_celestial.aac

ffmpeg audio format conversions:

https://linuxconfig.org/ffmpeg-audio-format-conversions#h1-3-1-ac3-to-mp3

Convert aac to mp3 with ffmpeg:

ffmpeg -i audio.aac -acodec libmp3lame audio.mp3

Cortar o unir mp3

sudo apt-get install mp3wrap mp3splt

Now you can merge two mp3 files (let's say 1.mp3 and 2.mp3) by typing:

mp3wrap merged.mp3 2.mp3 1.mp3

note that the merged.mp3 will start with 2.mp3 and finish with 1.mp3

You can split mp3's now by typing:

mp3splt merged.mp3 0.0 1.2 3.4

this will split file merged.mp3 into two parts:

00:00 - 01:02 01:02 - 03:04

where xx:xx represents minutes:seconds.
