EQs?
And how would I save the sound in a higher-quality format?
First, let's talk format.
What program are you using to record your audio? You're probably saving the audio as an MP3 before putting it in the video, so what quality of MP3? 192 kbps? 96 kbps? 128 kbps? Those options should be changeable if you're using a half-way decent program to record, either when you're saving the file, or when you're making a new file. Fool around with the options and see if you can find anything that lets you adjust quality. You want at
least 192 kbps. More if possible. Failing that, and if you have the hard-drive space, trying just saving it in Windows PCM wav (Uncompressed WAV). No quality loss, but the files are pretty big.
Secondly: EQ.
EQ is short for Equalizer. You'll see it in all sorts of music play-back programs like Windows Media Player and Winamp. A graphic equalizer will let you change the dB (Or, basically, volume) of different parts of the audio range with a file. Basically, it allows you to adjust the high, medium, and low end of the audio frequency. Even more basically, it means you can increase or lower the bass (Low end), treble (High end), and...the mud (Mid range). Learning to adjust these to make your voice pop out like a pro is a 'must'. Any audio producer worth anything will know the value of proper EQ-ing.
Here is an example I threw together at work:

Adjusting the levels across the range can make all sorts of different audio effects, from the barely noticeable to the drastic. The trick is using it properly to maximum effect.
