Madlib's Techniques
So, you want to know how The Beat Conducter does it? Well, Remix asked him.

“We usually de-ess maybe 4 dB off of the vocals and then compress with a ratio of 8 to 1, which is pretty high,” studio engineer Dave Cooley explains. “But Madlib likes his shit loud, and it's mixed loud to begin with. He has a really cool ‘angular’ mixing style: Something is always sticking out.”
