How To Choose the Right Vocal Effects VST for You


  1. Assess Your Needs


Before selecting one of the best vocal plugins, determine your specific requirements.


Are you looking for pitch correction, formant shifting, vocal harmonization, or creative vocal effects?


Determining your needs before you take the plunge can save you some real frustration.


  1. Budget


Vocal effects VSTs come at various price points.


Some are free, while others require significant investment.


Establish a budget that suits your needs and prioritize plug-ins that fit within that range.


  1. Compatibility


Ensure that the VST you choose is compatible with your DAW and your operating system before purchasing.


  1. Ease of Use


Consider plugins with intuitive and user-friendly interfaces, especially if you’ve never used a vocal VST plugin.


Advanced Vocal Effects Techniques


Once you get acclimated with these Vocal Effects VSTs, it’s time to get extra creative!


Try out these advanced techniques to blow the competition away.


  • Layering Effects


Combining multiple effects, such as reverb, delay, and chorus, can create unique and rich vocal textures.


Experiment with different combinations and settings to achieve the desired sound.


  • Parallel Processing


Instead of applying an effect directly to the vocals, create a separate auxiliary track with the effect and blend the dry and wet signals.


This technique allows for more control over the balance between the processed and unprocessed vocals.


  • Automating Effects


Use automation to vary the intensity of an effect over time, adding dynamic changes to the vocals.


For example, automate reverb levels to create a sense of depth and space in specific sections of a song.


  • Creative Modulation


Employ modulation effects, such as chorus, flanger, or phaser, to add movement to the vocals.


Experiment with different modulation settings and speeds to achieve the desired effect.


  • Formant Shifting


Alter the vocal’s formants to change the character of the voice.


This can create gender-swapping effects, robotic sounds, or subtly change the vocal’s timbre.


Final Thoughts


Remember that the key to achieving the best vocal effects is experimentation… and, of course, finding the perfect vocal effects plugin for you.
