Yes, that's the long version and it tends to tilt toward Windows (right-click this and that). Do you have an existing web site? Who authored it?
This is my Sound Tests and Clips web site.

If you click on any of those clips, the browser will try to play them live. If you right-click (or Control-Click on a Mac) the system will offer to download them. There's no flipping windows or rippling rainbows or auto launching whatever. It's pretty simple.
I'm not a beginner, but I did write all that in Notepad. I did not use a multi-hundred dollar web authoring program.
The Audacity instructions should get you through actually producing an MP3 sound file (best compatibility world-wide) and then you need a program that can post work to your web site. As a separate event, somebody needs to write some internet HTML code to make the sound file visible.
I have a number of test sound files that are dangerous. They exist on my site, but there are no pretty pictures to click on to get them. You have to know where they are posted ahead of time. The point of this is that posting a sound clip so one person can use it and making it commonly visible to the whole world are different steps.
Notes on posting files:
-- Audacity preferences should be reset for 44100, 16-bit, Stereo. Audacity doesn't come that way automatically. You can get oddball MP3 files if you don't do that.
-- Post multiple files. "PasterRasmussenFirst_20_Minutes.mp3" PasterRasmussenSecond_20_minutes.mp3, etc. Trying to manage a 90 minute performance in one go is not good.
-- Keep to surgically correct filenames. Upper and lower case letters, numbers, underscore, and dash. That's it. No spaces. No other characters. The filenames in the above example are correct.
-- File Extensions. Do you have Windows set to show you file extensions? This will be a lot less confusing if you do that. My Computer > Tools > Properties > Folder Options > Show File Extensions of known file types.
So give us an idea what you already have and we'll fill in the holes.
