Alternate Quick Audio is a slick program that will allow you an easy way to record WAVs or MP3s, and more.

It also includes a stripped down to essentials audio converter, which supports several audio formats (AU, AIF, MP4, M4A, OGG, WMA, etc.). If you are looking for an extremely easy-to-use audio player/converter, then Alternate Quick Audio will fit the bill quite nicely.
