Tips for Tracking/Mixing Rap Vocals, Part 2: Mixing the Lead

In case you missed it, check out Tips for Tracking/Mixing Rap Vocals, Part 1.

The other day, Shane from http://www.platinumgoldstudios.com/ and I got to sharing some techniques we use when tracking and mixing rap vocals/ad libs, and we thought we should make them public so you all could benefit as well. We’re not trying to be comprehensive here. We just want our share of the theoretical millions available for bloggers :-)


Okay, so you’ve tracked clean leads, now what do you do with them? In this post we’re going to addressed mixing techniques for standard leads only. We’ll talk about the doubles, ad libs, and special effects in later posts.


EQ
Slap on a High Pass filter to get rid of any low end rumble that may have been captured during tracking and/or to make room for the kick/bass. Just don’t kill the warmth and natural bottom end of the voice. Try somewhere between 75-120Hz. If the voice is too “thick” or “boomy,” a dip with a peak filter around the 150-300 Hz zone will probably be more effective than rolling off a bunch of low end. If there’s competition with a double, try pulling out around 300Hz to eliminate some of the thump. You’ll probably want to slap on a high shelf at about 8kHz or higher to bring out some clarity and presence (“air”). Sometimes you’ll need to dip as low as 4kHz. This can also make sibilance worse, however, so apply carefully and use a de-esser as needed. EQ other areas as needed to cut out junk and/or boost goodness. Be careful boosting around 2-4kHz. It’ll add presence, but at the expense of being harsh over time.

Parallel processing the lead is a great way to make it fatter while also preserving the dynamics that contribute to emotional impact. Try pulling out the lows on the squashed version so it doesn’t accentuate any mud or boom. Also try boosting the highs after the compressor on the squashed copy to bring back the clarity you might have lost after compression. If that’s not “in your face” enough, try out this “Vocal Exciter” trick courtesy Ill Will from http://www.phatassmixes.com/ (@IWStudios): http://www.youtube.com/watch?v=lYPdJjDg7UA

Reverb/Delay
Spit is usually dry, but try adding a tiny bit of short plate or medium-room reverb to help make the voice sound fuller. We’re talking percentages under 15%. A little goes a long way. Roll off the lows up to 700Hz if needed, and trim the highs down to as much as 8kHz. Long stereo delay (1/8,1/4, 1/2) has found its way into many current rap/pop hits and can be affective at times. To add interest, make the right side delay different from the left side (for example, an 1/8th note on one side and a 1/2 note on the other). Don’t overdo it, or it will sound comical or just confusing. Roll off highs if the delays compete with the lead. Go as low as 1kHz if needed. Roll off the low end of the delay if it’s muddying things up. Sending the delays to the reverb helps soften their impact as well. Adding a short delay (under 40ms) can also add some more weight to a voice. Just mix in the delay lower than the lead and try rolling off the highs so it doesn’t fight the lead in the clarity zone. Longer delay times (between 40-200ms) can also imitate a doubled sound as well, but is pretty static sounding after a while. Hard panning a delay or reverb in mono can be fun but isn’t very common. Whatever you do with delay, play with feedback time and adjust to the needs of the track. One repeat can work, but several are sometimes needed.

Heavy Metal
Blending in (parallel processing) some mild distortion can also liven up a voice and make it more interesting. Exciters can also work wonders. Limit the bandwidth of the hyped processing, however, so it doesn’t dominate. The goal is to add subtle texture, not deep-fry it into oblivion. Avoid adding too much crispiness or your listeners will unconsciously recoil halfway into the verse. Re-amping the original signal to a distorted amp can produce cool results as well, especially if you feel like you need some more "air" (in the mic sense, not in the EQ sense) around the distortion part.

Panning
Keep the lead panned dead center. There are times when you want the hard left/right doubled sound, but we’ll talk more about that when we get to hooks and doubles.

Style
Work with the producer and artist to determine what their vocal processing style should be. Your work may determine the sound of every other recording they make in the future. Many artists think there is something wrong with the mix when they just aren’t confident hearing the sound of their own voice. If they sound solid, supportively argue for less “cover-up” processing. If they really do suck, some kind of signature processing might be what they need to feel less embarrassed about their abilities. However, don’t process just for the sake of processing. A single dry line might be all that is needed (“Toot it and Boot it” anyone?)


The tips offered here are just possibilities. The strength of these tips depend on what’s currently in style and how “pop” the artist wants to be. Apply them only if needed, but don’t be afraid to experiment.


Happy Mixing!
