I suppose someone could make a plugin.
There is an easier alternative if you are lazy like me
.
The player is a free download.

Alternate to a plugin,
Download the player, get the code for the player you want there, then put the flash file and your mp3’s in a directory.
Make a custom field in your entries, I was original and named it mp3…
Put this in your template changing to match your player swf file:
{if mp3}
<object type="application/x-shockwave-flash" data="/foldername/emff_standard.swf?src=/foldername/{mp3}" width="110" height="34">
<param name="movie" value="/foldername/emff_standard.swf?src=/foldername/{mp3}" />
<param name="quality" value="high" />
You need flash or other alternative content here
</object>
{/if}
To make it easy to upload an mp3, use your file upload folder, make sure to put the flash file there.
Now anytime I upload or want to add an mp3 flash player to my posts for audio voice or music, I just type in the filename in the field and upload it if needed.
