Purchasing SSL certificate for stream

My radio stations internet streaming server is http://audio-ice2.ibiblio.org:8000/wsoe.mp3. I need to change the stream from an HTTP to an HTTPS stream in order to work on our website. How do I go about doing this?

Your stream is available at https://audio-ice2.ibiblio.org/wsoe.mp3 already, so no certificate purchase is necessary.

Thank you so much I appreciate it. I couldn’t seem to find that link.
