I tried to listen to this sermon a few times at work but even in near perfect silence it was hard to hear so I took it into Adobe Sound Booth and raised the volume and equalized the audio.
Here's the link, feel free to download it and upload it here:

The sound quality is good now and I should be able to listen to it at work. :-)
Peace!
