Not only is compression on the vocals okay, it's standard practice. You definitely need to level out the soft and loud spots. Just don't overdo it. You need to maintain some of the dynamics to keep it sounding natural.
Thanks, Leadfoot.
So, what's a good rule of thumb for maintaining dynamics? What should the range be in decibels?
The reason I'm asking is that in William Edstrom Jr.'s "Mixing with Sonar" video tutorial series, he makes adjustments as small as one db when leveling the lead vocal track and to my way of thinking, that doesn't leave much room for dynamics. And this is a track where the vocalist was obviously going for dynamics in his performance.
