You can keep any recording just as raw as you want. If you like the sound of the initial play-back, then just use that. No EQ (tone control) reverb (echo) compression (boosting the middle) or other effects are necessary. Some radio stations will choose not to play it because it'll sound somewhat strange (to them) alongside the rest of their output - but don't let that stop you!

The only thing you need to do is decide how loud each track, and each track, should be.

And by that I mean a) the relative volumes of your voice against the other instruments (and here you can just lean over and turn the other tracks up or down using the faders until you're happy) - and b) how loud each song or tune is alongside its neighbour.

For this you'll need to use a combination of your ears and whatever visual guide the studio has - ppl, vu etc - so that the listener won't have to keep lurching for the volume control.

But is there a another problem? When you say you liked the raw vocal - do you mean the sound you heard in your headphones when you actually sang, rather than the initial playback of the recording? Because if the playback was not to your liking, then the chances are that, as you sang, you were hearing your voice on the way IN to the recorder rather than on the way OUT. That suggests that he's using a good mic, but not a good recorder, so some frequencies are lost on the tape or disc.

But that's unlikely these days - so I assume you mean that you don't like the mix after he's fiddled about with the knobs for a while - in which case, see above.
