I saw that threr really isnt much audio help here so, i deceided to write these

1)Transform... Amplitude... Dynamics Processing... "Vocal Limiter"
This will boost your mid-range and allow you and the beat to blend better at a lower vocal volume... caution... this will even out your sounds so your breathing will be magnified... you might want to edit your breaths down to 25% volume

2)Transform... Filters... Graphic Equalizer... "Vocal Presence (cut)"
This will clarify the mid-range on your voice so your shit can be bumped

3)Transform... Filters... FFT Filter... "Bass Cut"
This will take some of the unnecesary rumbling out of your voice and you will be more audible

4)Your choice of a light echo.

5)Make sure all sizable gaps in your verse (such as the intro and and end) are silenced

6)Make sure you strategically allign your acapella and the beat. To do so with as much precision as possible, zoom in closely and make the small moves necessary to perfect your production.

Cool Edit phone effect...

Effects>Filters>FFT Filter> you will see a few phone effects

My way:

Effects>Filter>Quick Filter> Old Time Radio x 2 (do it twice).

This is old school, but it works, and I still do it that way.
