Lol, after reading a lot of these answers I have to chime in on this. To the OP, the BEST compression is knowing how to use your voice and mic. Also get the BEST mic that fits your style that you can afford. Condenser mics are NOT always the best choice. Knowing when to back off and when to punch in the vocal dynamics is a must! Mastering this will lesson your need for compressing the hell out of your vocals. The 1st thing I do with vocal tracks, and I mean the VERY 1st thing is EQ them.
some ideas for EQing....
ADDING freqs, look at adding around 1-2K, 7K
boxy is usually heard in the 200-500 range. In the case you want to add, I start with a wider q filter .... 2.4-1.4, add a good boost, maybe 6 dB
sweep the frequencies between 1-2K slowly to find the growl in the voice
go back and forth until it doesn't stand out against the rest of the voice.
when I find it I start sharpening the filter and readjust the freq
Now I have the growl, I add sparkle with the 7K. depending on the room it was sung in I will either use a bell filter or a low pass
If the room is hot and shiny (hard walls) I low pass above 10K or so. Then I add a boost at 7K
The initial comp is at 12:1. The comp is very transparent and you can add goobs of comp without hearing it ...
Spend a good amount of time listening to the raw track without processing.
Recording and mixing vocals is an art to itself. Takes a lot of time and practice to achieve the desired effect you are seeking.
My vocal chain is usually set as follows
De-Esser, Compression, EQ, Reverb. If I want a nice warm sound I'll add some saturation in there is well.
Another rule of thumb to remember (though all rules are made to be broken...lol), if you can hear the reverb on the vocals then chances are you are using too much, unless of course that is the desired effect you are shooting for
