Hi everyone! As I said in my first post , I am not a programmer, but rather an amateur. I tried to write my crafts in different languages, but I started with Java. Most of all from the Java family, I liked the JavaFX platform. More precisely, a bunch of JavaFX + FXML, where we write the logic in the controller, and describe the graphical interface in a separate fxml file. The radio is just written using this bundle.
The JLayer library is used for playback. The built-in class MediaPlayer for some reason refused to work for me. Recording and playback are done in separate streams. For the sake of experiment, I tried to start playback in the main thread of the application. I got a tightly frozen interface. I got the same thing when I tried to write in the main thread.
