Uploaded Reverend Charley Lerrigo's sermon.
I used Mp3Gain to boost the volume of the mp3 file. Technically, I increased the mp3 gain from around 75 decibels to 95 decibels.

If you've already downloaded the earlier sermons to your computer or mp3 player you may want to re-download the louder versions. So far the only mp3 left to replace is Pastor Lynice's Easter sermon.
