Like other players based on MPV (SMPlayer, ...), please allow passing arguments to MPV so that is possible to add audio or video filters. As an example, boosting the center audio channel, which is a very common audio feature in Windows players, is possible via this method, otherwise we can't add those custom features in Haruna on our own. (e.g of filter for boosting center audio channel: lavfi=[pan=6c|c0=c0|c1=c1|c2=2.0*c2|c3=c3|c4=c4|c5=c5] ) SOFTWARE/OS VERSIONS Linux/KDE Plasma: 6.1 lts KDE Plasma Version: 5.27.9 KDE Frameworks Version: 5.111 Qt Version: 5.15.11
You can with custom commands. https://haruna.kde.org/blog/2024-05-21-interacting-with-mpv/
