Record your vocal with the best quality microphone available. Match different mics to different voices if you have a choice, using your ears as your guide. Adjust the microphone, the singer, and the position of both in your recording space to achieve the best sound. Set your recording level as high as you can without distortion.
Add or remove frequencies to the vocal track as needed to adjust the recorded result using the Sonitus equalizer built into each track. Things to address may be slight nasal sounds, sibilance (harsh "ess" sounds) or thinness of the vocal. Additions and subtractions at this stage should be small, a few decibels (dB) at each problem frequency, unless you are attempting a special effects vocal.
Use pitch correction software next, if it is available, to correct any performance issues. If you recorded multiple takes of your vocal, consider making a composite of the best pieces of each take, or simply use a word or phrase to correct pitch, if a plug-in is not available.
Add compression or limiting to help even out the level of the vocal and help it cut through backing tracks. SONAR has several built-in compressors, limiters and dynamics processors, depending on your version.
Apply reverb, delay or both to the vocal to give it a sense of space. Plate, and small to medium room presets are a good place to start. When you have the preset you like best chosen, adjust parameters, particularly pre-delay and duration, to match the time delay to your performance.
