Editor In Chief Paul White replies: You don't say what kind of mic you're using but some dynamic models with harsh presence peaks can sound somewhat nasal. However, any halfway decent mic should be able to deliver a good, balanced vocal sound with little or no EQ or other processing. The trick is to get the sound as good as you can at source before thinking about processing, though the following guidelines on EQ may be useful if your voice itself is really the source of the problem.
The standard technique for identifying the offending frequency range is simply to set up a narrow-band EQ boost and sweep it across the frequencies until you find the spot where the nasal 'honk' is most pronounced. You can then place an EQ cut at this frequency, which is likely to be in the 800Hz to 1.5kHz range. Once you've found the right frequency, increase the Q to narrow the cut band until the honk just starts to come back, then reduce the Q slightly again so that you're making an EQ cut that's no wider than is really needed to get the job done. It's also a good idea not to use more cut depth than you actually need, as too much EQ is nearly always detrimental to the sound.
However, room acoustics can also cause honkiness so make sure that the room you are recording in is fairly dead-sounding. You can reduce room coloration by hanging a duvet behind your singing position to dampen any reflected sound bouncing back and into the mic. Moving slightly to one side or to just above or below the mic can soften the sound of the vocal slightly and the best way to judge this is to monitor through headphones while you sing, then move your head around until you find the best position.
