The focus seemed to be on the flaws in how others perceive us. I wanted to raise the issue of how how flawed our self perceptions can be. I think I could make a string argument that others perceive us more accurately than we perceived ourselves. Shoot, Facebook's software knows people better than they know themselves. But of course I may have misunderstood what you said and stand corrected.
(1) You can use embed code as you have done above. You may also use standard HTML markup code to insert audio directly, as shown below
<div id="audio" class="audioplayer" style="padding:10px;margin:10px;border-style:solid;border-width:1px;border-radius:5px;"><p>Listen to an Interview of Troy Johnson Interviewed by <a href="https://aalbc.com/authors/author.php?author_name=Lee+E.+Meadows">Lee E. Meadows</a> on Detroit’s WPON’s “Book Beat” February 4, 1999</p>
<audio controls>
<source src="https://aalbc.com/audio/troy.mp3" type="audio/mpeg">
Your browser does not support the audio element.
</audio>
</div>
As demonstrated below:

Your browser does not support the audio element.
So while this is possible the issue is where will you host your audio file? As you can see from the code above. My audio file is located here: https://aalbc.com/audio/troy.mp3
If you have a place to store the audio file (your website, maybe google drive, etc) you can use the code I provided above to insert your audio. Maybe google drive
(2) Promote Feature: is actually pretty powerful. It allows you to promote a post here across multiple social media platforms. It is better than most social sharing options in that you can customize the posting across that different platforms
(3) Probably but I'm have to research this.
(4) Cool. There are many features of this discussion forum software that I'm not familiar with. A couple of weeks ago I applied a major upgrade that improved the software and added new features including the concept of clubs, which are analogous to groups on Facebook. The developers of the software appear to be implementing many of the popular features available on social media (without the invasion of privacy)
