Bear with me, I'm a novice with this but searching on google doesn't help me (not simple enough).

I'm needing some sections of songs to load onto a sampler for presentations, room introductions etc. I've been told audacity is my friend when trying to make these samples but I just can't get started. I can load a song up, play it but that's about it

All I'm wanting is to take small samples from mp3's already on my computer - any advice ??
