Need help with raw vocals

Producing a song and just need some help with some raw vocals. My singer did some vocal recordings in mix track and they seem a bit flat. Need some treble,is there an onboard eq in audacity? Im a guitarist so i dont know much about audacity features. I have a few tracks, instrument, effects, vocals and backing vocals and just looking to make the vocals a little brighter or tighten the whole thing up, make it sound like a mastered cd track. I know power tracks used to have a real audio tool that pretty much polished your end mix to make it sound tighter. Thanks

There is Effect > Equalization.

You can click and draw lines for emphasis, or switch to Graphic EQ and it will give you sliders like a music system.
