What the Best Mac Program (hopefully free) to Enhance Audio?

I've been recording sermons by my mom at her church. The microphone isn't the best that I use isn't the best (I really can't afford to get a better mic), but I turn the MP3 into a video file and put in on iMovie to enhance the audio. It works, but it's a rather clumsy, hard drive consuming way to enhance the audio.

Without sounding like a dummy, is there an app for a MacBook Pro for enhancing MP3 audio directly? (Hopefully a free app?) I have Mac OSX 10.6.8.

Thank you.

First, try not to record in .mp3, but record in .wav format instead. If you're forced to record in .mp3, choose the highest bitrate possible, preferable 320 kbits/sec.

Then, to actually enhance the audio / reduce noise download Audacity. It has many useful filters which will suit your purpose.

When you're done enhancing the audio, don't save the audio again to .mp3. but rather save in uncompressed .wav. If you save to mp3, you'll be compressing the audio twice, and it will sound very poor / tinny, or like water is rushing through the sound.

If you've been able to record the audio in .WAV format first, it would be OK to save the final audio wavestream in 320 kbit mp3 instead of uncompressed .wav.

Are the sermons going through a speaker system? Are you just using a mic to pic up the audio from the speakers, or is there a way to patch in a feed directly from the audio mixer/amp?
