i have a "Player" class, which is supposed to manage my global music player. This also works so far. The class is at the bottom, if you have any suggestions for improvement, feel free to give it to us.
I want to start a second song while the current song ends. So a FadeIn into the next song and a FadeOut from the current song, which makes the song quieter.
My approach at the moment is that one song is running in the "waveOutDevice1" object and the second one is waiting in the second object. And as soon as the current song is about to end, the second WavePlayer starts. But I don't know how I can react to it, as soon as the current song is about to end.
Do you have an idea or suggestions? With kind regards
my Player class:
public class Player
