Howdy, we (being SCP and WL) have our own audio player module courtesy of the great Woedenaz. You'll see it used in several of my articles, like this recent one you may remember.
.mp3 and .wav files are going to be your best bet for this, so if Noteflight allows you to export or render as one of those two file types, I would do that. Second thing is, you actually have to upload the file you want to use to the WL wiki. I'll admit it's a little bit of a clunky process.
Once you create a page, hit the Files button down where the other buttons are, like the Edit and History buttons. Then, click "Upload a file from your computer" and then do just that; upload your audio file. Once your sound shows up in the list of files under your article, click Info. Copy the full text string of the "Full File URL" into your clipboard, and hold onto it.
Enter editing mode on your article again, and add the following code where you want the audio module to go:
[[include :scp-wiki:component:audio-player-woed-source
|unique-name=
|audio-file=
|background-color=rgb(45, 70, 45)
|border-color=rgb(12, 12, 12)
|border-radius=0.313rem
|dropshadow-color=rgba(12, 12, 12, 0.15)
|text-color=rgb(250, 221, 98)
|icons-color=rgb(250, 221, 98)
|player-color=rgb(45, 70, 45)
|progress-color=rgb(151, 135, 80)
]]
Above, you see empty spots for Unique Name and Audio File. Unique name is unimportant, you can put anything you like there as long as it doesn't have special or code characters that will mess up the module.
For Audio File, don't leave a space after the equal sign, and paste that file URL you had in your clipboard from earlier.
Save your article, and after a moment, the length of the sound should show up on the player box in the article, and then you'll be able to play the sound.
Hope that made sense, and do feel free to DM me if it continues to give you trouble.
Best,

P.S. - Please also feel free to examine the file info and page source for that article I mentioned; or my Library Theme Songs gallery.
P.P.S - If you find you're unable to render your sounds to .wav or .mp3, I have the tools to quickly do so for Midi files. No promises on seeing my Wikidot PMs in any decent amount of time, but still.
