Following the link below you can listen to and control a short-wave receiver located at the University of Twente. In contrast to other web-controlled receivers, this receiver can be tuned by multiple users simultaneously, thanks to the use of Software-Defined Radio.
This doesn’t mean that you listen to others tuning the radio. You have free control over what you want to tune and listen to. Other than tuning the radio yourself, there’s also a chat room where people post stations that are operating/audible to the antenna (remember that you are listening to the reception of a physical short-wave radio and not an internet radio).
There is also the function to record the audio output and download it as a 16bit Wav file. I used some recordings in my 2019 release In Search of Shadows in the track Radio Receiver.

This little board is the brains of the system. It samples the whole radio spectrum and sends it to a PC, which is then where you listen to your radio station from.
