When it comes down to vocals, the lower frequencies are important because they can both enhance and hinder.
For 100Hz+, these will provide power and body in your mix.
But anything below that frequency is going have an adverse effect on what’s happening with those aforementioned qualities – plus there’ll be noticeable plosives or microphone rumble (especially if you’re using a condenser). These things are going cause overall issues for not only yourself but also everyone else who has part of their sound coming from you as well!
This is a great guide on how to clean up your vocals!
To start, you should use an EQ and cut the frequency range of 100Hz.
This will reduce any unwanted noise in the lower end spectrum such as background interference or amplified frequencies from other sources like instruments that are playing at similar levels. Additionally, using natural phase options can help eliminate some problems with phasing if there’s too much cancellation going on when it interacts with another instrument played higher than this vocal track for instance.
