Is there an audio auto-leveler for Windows Media Encoder 9?

[Sin D]

I'm using Windows Media Encoder 9 to record and encode live audio during presentations. The issue I'm running into is that if I'm not paying attention to the audio gain on my soundboard, the input stream can be either too loud or too quiet (depending on who is speaking). Is there some sort of audio auto-leveler within WME9 that monitors these incoming audio streams for me so they don't max out while I'm out of the room?
