Use the right microphone(s) Not using the right microphone can result in an awful vocal track, so make sure you are actually using the right one. Condenser microphones are what you’d normally see in studios, and probably what you should be using. Dynamic microphones work for some vocals and styles, but obviously not everything. Compare the two and use the one that fits your recording needs.
Record with good-quality cables If you want a high-quality recording, it’s ideal to invest in high-quality equipment. Cables do matter even though they may not matter as much as the microphone you’re using or the kind of pre-amp you have. They still have a say in the overall sound of the record, so don’t go cheap.
