Analogue input to create visuals

I'm attempting to play an analogue signal (a record player) through winamp so I can use the visual capabilities of winamp. I need the visuals to be in realtime so they are in time to the music so that I can use the visuals at parties with DJs playing. How can I do this?

This question has been asked at least 4 times in the last month. Use the search feature of this forum to locate one of them.

I guess even the *BRIGHT RED* text saying "Be sure to use the search feature of the boards before posting a new topic." doesn't work 🤪.
