This repo contains 2 very simple scripts that call fmmpeg. You can use it to take a large audio file with multiple songs and split it by song using the silent pauses between songs. Currently it will separate small fragment files produced (little segments of silence or a short segment between songs) and move them to a separate folder called "junk".
Clone the repo:
git clone https://github.com/shawnschulz/audio_splitter.git
Make sure ffmpeg is installed:
sudo apt install ffmpeg
Next, it's easier to use the script through an alias (you can put in .bashrc or PATH if you'd like)
cd audio_splitter
alias audio_splitter=$(pwd)/auto_splitter.sh
alias mkv_to_aac=$(pwd)/mkv_to_aac.sh
Take your .mkv file from an obs download and convert it to an aac, then run the audio_splitter script
touch junk
mkv_to_aac filename.mkv
# When done a number of audio files will appear in your folder
audio_splitter filename.aac
