Basic Vocal Recording Techniques and Tricks of the Trade

Before you record your next vocal track, take a moment to consider a few basic best practices which will improve any vocal recording. Keep in mind that once you get the performance down, you can always add effects or dirty up your track later, but starting with a clean track is always the best.

Good mic technique basically means you need be aware of two things. Firstly, understanding that each microphones diaphragm reacts with varying sensitivities to all the subtle variations in your vocal delivery. Secondly, developing the skill of being able to adjust your body position according to the dynamics of your performance.

For vocal performance that remain soft and intimate from start to finish, the singer should stay positioned just a few inches from the mic. For louder, full volume singing, stand back two or three feet and let loose. If your delivery requires a mixture of both, then you need to move in close and back off the mic as needed. Start getting used to doing this even if its just for a couple words or a short phrase.

Ideally, your mouth should be as close as possible to the mic without overloading the level. If you overload the level, two things can happen. You will either end up with digital clipping on your track, or in the case of super-sensitive mics, the mic itself with temporarily shut down. Both of the scenarios effectively ruin your recording. The easy remedy here is just to aim your mouth slightly off to the side or above the mic during loud bursts.

Mouth pop and lip noise can easily be rectified. Stage mics like the Shure SM57 and SM58 have a pop-filter kind of built in. Stage mics generally have a foam layer just behind the ball shaped mesh protective grid. Many musicians and engineers submit that these dampen om high end frequencies, and prefer the nylon stocking style O-ring pop-filters. Positioning one of these between the performer and the mic will effectively eliminate any uncontrolled blast of breath from overloading the mic.

Avoid recording annoying mouth noise. Its and easily avoidable situation that requires minimal effort to correct, and makes a big difference in the end. Ok, brace yourself, here it is: drink lots of water, or have your singer drinks lots of water. It will go a long way towards eliminating unwanted mouth noise, and a few extra trips to the bathroom is a small price to pay.

If you follow these simple rules, you will start with a nice clean vocal track. From that point you are free to add reverb and whatever crazy effects you can dream up without enhancing the unwanted noise when you’re trying to get at the meat. These simple practices will save you hours on Mr. Fix-it time in the end.
