Karaoke player with built-in web remote client
[ О приложении ]

Karapulse is a Linux karaoke player supporting CDG/MP3 as well as video files.
It provides a self-served web application that singers can use with their phone to search for and queue their favorite songs.

Once installed you'll need to index your songs collection.
This can take a while if you have a lot of songs but needs to be done only once.
To do so run the following command with the directory containing your songs ($HOME/karaoke in the example):

flatpak run --command=karapulse-manage-db org.karapulse.Karapulse add-dir $HOME/karaoke
